Vibram FiveFingers Weather and Airport Update: keep your VFF's ON!

Ok, so on this ides of March (vale, Ceaser) yet another post about vibram fivefingers (previous one here), but what the heck. This is two surprises: airports and freezing cold streets.

COLD WEATHER - just add sox.
Much to my surprise, i've found that even in -1C, the Flows are great outside on pavement when paired with a pair of injinji sox. These were the temperatures i found myself experiencing in Indiana this past week when the temperatures dropped from 21C to below freezing. That my vff footwear still protected my toes from frost bite made me very happy.

One thing that is a bit of a challenge is the polar opposite of that kinda dry cold: up in Canada, the weather went from -20C (very dry veeeerrry cold) to +1. Slush resulted. Puddles with every ice melting step. This is not fun for flows - the toes will get wet as the gunk comes up over one's tootsies.

Take away: bare feet can do around 4C well; colder, just put your sox on in the flows and as long as it's dry, well you've just extended the wear life of free feet.

AIRPORT SECURITY
I've recently gone through 10 security checks in one week. Each time i had my vibrams on. Not once was i asked to take off the flows. Indeed, most security staff commented on how great they looked and how comfy. They took them to be sox, and i did not dissuade them. Maybe it helped that i had a pair of sneakers in the bucket (was carrying these around for the -15 weather).

Anyway, VFF's are fabulous for being on a plane - you just feel more stretched out and loose and comfy. best ever. way better than just sox. And now, here's one more EXCELLENT reason to wear them for travel.

I need cards with VFF links on 'em the number of times people in airports ask about 'em (by the way Vibram doesn't pay me a cent for promoting their foot ware; it's just the right thing to do).

So, go ahead, if you travel much, you'll be glad you have one less thing to manage after stripping down, pulling out a lap top, pulling out your liquids and all the rest. Keep your VFF's on (the flows do look the most sock like).

Vibram FiveFingers - Review 5 months on - New Body?

After five months of wearing vibram's fivefingers (vff) footwear pretty steadily anywheres indoors over the winter, and now again finally outdoors, a few things have happened: my gait has improved (i credit z health drills with free footing footwear like the vff's), but in particular
i don't like wearing shoes anymore - even sneakers. They feel - funny. And what's weirder still - heavy.

Since i wrote about how to fit vff's , it's been cold and wintery, or cold, wet and wintery, and i've been wearing the vff's mainly at the office and at home - not outside. And they've been great. They've been particularly super in long haul airline flights - so nice to wiggle toes, get a bit more comfortable and be able to go for an aisle stroll to stretch. I've been glad of the Injinji toe socks as liners for these to keep the feet a treat warmer, but the main thing is, these shoes induce positive change not just at the feet, but in overall being-in-the-bodiness. This enhancement/awareness may be in part because my feet are now connecting more with the world more of the time. That perhaps enhances or better enables the proprioceptors in my feet to say where they are in space. Also, because the foot is more free to move, a more natural and appropriate gate is coming back. It's a treat to ditch the orthotics. Why is wearing thin soled foot wear with toe pockets such a big deal?

Proprioceptioning the World through Sole(s)
One of the issues with shoes is that they separate us from the environment. Now most of us would see this as a good thing. For those who like their kodiaks or other steel-toed work boots for office attire, we fear something could drop on one's foot - a block of photocopier paper perhaps - and that would smart. And outside, there are hazards on our streets, we feel. Broken glass must be everywhere. We want to protect ourselves from that. That's what a thick sole provides. Or because these concrete roads and walks are SO unnatural, we want shoes with extra cushioning to protect ourselves from these surfaces. Similarly, standing on our feet all day, surely we want the best cushioning?

Everything affects everything?
The costs of each of these foot binding strategies is two fold: awareness and gait. If we wear padding we don't have to be so aware of moving around objects that might bump into us. If we don't have to watch where we put our feet and can be casual about our stepping - in fact step poorly because there are no consequences to our feet, does this lack of movement subtlety or envirnoment awareness start to impact the rest of our bodies?

Take gait: problems with gait in running - such as over pronation - are often addressed by orthotics - and artificial support placed in the shoe - rather than on thinking about the whole movement and improving the gait itself - as if gait can't change. Gait is not just something that happens in the foot. It's a whole body movement. If something is hinky in the foot, it will work its way up the chain through the rest of the body's connections with stride and each step we take. Orthotics (by way of example) also only focus on the foot as both the site of the problem and the solution. But what if the problem starts in the shoulders or the lower back and just manifests in the foot that seems to over pronate? So what does this have to do with thin soled shoes?

When our feet are in inflexible, well padded sneakers, say, we actually have less awareness of our gate - we are protected from it - that awful heal strike is counteracted in some respects by the Super Cushion, for instance.

What happens when we take off our shoes and run barefoot - outside. Most folks i've chatted with would not even contemplate going shoesless on sidewalks - never mind the oceans of rusty nails and broken glass, it's "the impact" of course that is feared.

And yet there are growing numbers of barefooting runners. Are they built differently than the rest of us?

Running Outside on Pavement without the Cushion
Here's where i've really noticed the change that z health and vff's hath wrought. I used to run alot of x-country. Now i occasionally run to work or home. When i first wore the VFF's and had my first run experience in them, ya it was a little funny - couldn't do the heel down at all without jarring myself silly - had to run up on the balls of my toes. But from what i read about gait and stride, that's not entirely "natural" either not to have the heal come into play.

Then the winter really kicked in and it became too cold to wear the VFF's to work. In the past few days, it's become warm enough a 7C to wear 'em again. And so i ran home - including a big down hill pounder that should really test heal work. And it was easy. Simple. Dare i say natural. Was not thinking about stride.

So intriguingly, at least to me, after walking around daily in VFF's *indoors* my stride is such that it's now easy to run outdoors. On pavement. In as near to barefeet as one's likely to get with some kind of foot covering.

Now i've been doing z drills to work on the over pronation that i have in my asymmetrical stride, and i'm looking forward to getting the improvement checked in a few months, but in the interim, i know that having barefoot like footwear has made it possible for me to be more aware of my stride - to feel the whole foot move. That awareness is both challenging to achieve in shoes, and then challenging to apply in shoes, since shoes are typically too ridgid to respond to the whole foot move.

Consequences are that the issues with my back are also finding greater relief.

So in the end, here's what i'm thinking: i had a z health assessment that helped me find appropriate drills to address my gait issues; i practice these drills. But i also practice walking. It's something most of us do every day, everytime we stand up to move to somewhere else. Where i work it's a long building. So walking from one end of the building to the other (90 secs) is a lot of steps. That's good practice. With the VFF's i can be far more aware of my feet - feel what they're doing across each joint. IT's very cool. Really. I feel like i am more in my body, more aware and just feel better as a result.

The down side - if it is a down side - is that i just reached a point the other day where i couldn't stand wearing my winter shoes anymore. They just felt heavy and it felt like my feet were all trussed up, and i just said ok that's enough. Lucky for me, i guess, the weather has turned sufficiently in the centigrade to allow me to wear a pair of VFF Flows. It felt quite daring the other day wearing them in the real world - onto the train platfrom, onto the train, walking around an unfamiliar city. But it was great. It was really great. My feet did not feel weighted down or tied it. It may be difficult to believe that one's feet *could* feel so encumbered by cross country goretex runners (what my winter "boots" are), but that's how it's been feeling.

I'm not quite sure what i'm going to do about some time i have to spend this coming week where it's currently -20C. Suck it up and wear the shoes, i guess, until Vivo gets its boot sizing worked out, and be glad it's only for brief jaunts.

Fashionistas
There have been a number of places where people have said "those look really comfortable - wish i could wear them, but i'd never get away with it where i work"- I wonder if that's true. If one could wear black pumps, why not black vibrams? or black crepe soled shoes, why not black vibrams?

Not that one has to wear VFF's - there are it seems a variety of thin soled shoes that many folks in the z community and other free-feet-is-best spaces suggest. My past 5 month experience has been with VFF's - i've enjoyed how light and easy they are to shove in my pack to get to work or take on a trip. I also like how my feet have adapted to learning how to be multi-jointed instruments again.

So, if you're contemplating freeing your feet, only half a year-ish on, at least in my experience, it's been entirely worth it. Recommended highly.

Carbs or Protein before Bed? Not what you think

Most of us have heard that having some slow digesting protein in our guts at night, making amino acids available for muscle repair after a hard day's training is a great thing.

We may likewise have been told to avoid carbs "they aren't necessary" i've heard one person write (yes i hear writing. all the time. creepy)

The thing is, some work around recovery suggests that it's just as important to get a good sleep - undisturbed and deep - for that growth hormone to release and do it's thing to. And guess what helps a good sleep? Yup. Carbs. Oatmeal and honey before bed, deeper sleep assured.

So, i'm gonna be looking into this further to get a handle on optimal ratios for best muscle/recovery blend...

Optimal Protein Blends - for carnivores and vegetarians alike

The following post offers some quick suggestions for tuning your protein types to optimize uptake depending on activity.

Carter Schoffer once explained to me why different kinds of proteins are a good idea, rather than using the usual Whey Protein Isolate by whatever company. The reason that has a lot to do with it (if i'm reflecting this correctly) is absorption rate matching to task.

After a hard training session when the muscles are crying out for amino acids, a fast digesting protein is a good idea. For vegans, gemma or pea protein seems to have the best profile. For dairy-ok folks, hydrolyzed whey has the best profile - better than isolate.

For protein during the day and over night, when you want to slow down the absorption rate, and have a more steady state feed of protein happening, slower absorbing proteins.
For vegans, hemp protein is a slow digesting source. Here's a resource comparing different protein types, too. (if that link goes awry, here's another).

For dairy-ok folks looking for anytime protein, casein/milk blends are a good idea. Especially if you follow Precision Nutrition's of protein and greens with every feeding, and need the convenience of say a Super Shake during the day, this second protein variant is great to have.

You can shop for protein powders that pre tin these particular blends. Or you can custom mix the blends you want at trueprotein.com (there's also a trueprotein.ca). There are several advantages to the TP approach. One of them is experimentation: you can order a pound of any kind of blend you'd like or any flavouring you'd like and not be stuck with a ton of it.

For instance, Luke Neilsen recommends this blend for a great anytime protein.
Milk Protein Isolate - 30%
Micellar Casein - 30%
Whey Protein Isolate Cold-Filtration -40%
It's recommended to include the aminogen protease and i prefer the BSL flavouring system but there again you can use any flavour/sweetener combo you'd like.

The price works out to 1-3 dollars a pound LESS than Metabolic drive, Evopro by Cytosport, or Propeptide.

Now if you do want to use pre-packed blend, i'd recommend bulknutrition.com (aka 1fast400.com) - they have excellent prices, good shipping, and frequent 10% off offers for returning customers. They're also very fast at responding to customer queries.

For the blends and customer service, TP is hard to beat. They also do some bulk supplements as well, so it's worth comparing prices regularly between bulknutrition.com and TP.

If you do order from trueprotein, you're welcome to use my discount code as well for 5% off your next order. The code is MCS110 - you'll enter it at the end of the order cycle.

Bones and Pistols: a start at B2D responses to readers' queries

This post provides a summary of what research suggests about what we can do to enhance bone strength - and especially when we can do it. It also includes a preliminary review of Steve Cotter's Mastering the Pistol DVD. All because of what b2d readers want to know :)

A little while ago, i asked b2d readers if there were any topics of particular interest to them they might like to know more about. Ron asked about Why Hardstyle (implicitly perhaps as opposed to GS?) - a part of a reply to that is in a recent post on early impressions of GS training which may or may not help Ron's quest.

One of the other queries was from supercat strongman Adam Glass on bone strength:
A few weeks back i posted a question relating to the subject of bone adaptation to stress- a law was recited back to me by several members. I would like to see some more information on bone growth-specifically how i can increase the resulting thickess and researched methods of enhancing bone strength.
I've been fascinated by bones ever since i had to study about bone formation for the CSCS certification. It's a topic i find rather overwhelming because SO MUCH is going on in bone. So rather than try to get into the intriguing complexities of bone development and growth, i've restricted myself to Adam's question.

A more detailed discussion of his question is over at geekfit. That seemed a more appropriate place for the article as it has finally given me something i've been looking for: an unequivocal imperative for desk jockeys in their 20's to get working out. Working out now for future ease from pain and disability may be about as exciting to think about as pension planning , but the results are in: bone loss is inevitable, and the best cure is prevention rather than treatment.

If you're interested in the topic, there's lots of detail and referenced research over at the article on geekfit, but let me quote the summary here:
While studies have mainly focussed on post-menopausal women, bone health - in particular bone mineral density - is a concern for both men and women. The best cure for bone loss is prevention rather than treatment, and the best approach for this prevention of inevitable bone loss is to bank it up with extra BMD work in childhood, youth and young adulthood. The best approach to do this loading is with resistive force work: power training, stop and start sports.

Nutrition is critical for bone building, but will not cause bone building any more than simply eating protein will cause hypertrophy. While we still don’t know what the optimal prescriptions are for optimal bone mineral density building, all the studies looking at this effect show that doing nothing is the worst approach; better to do some fast load bearing activities - but not over doing it, or one may have the opposite than desired effect with microfracturing the bones beyond repair.

Because of the critical effect of bone loss post our alas early peeking in life, it’s great to know that we can bank up bone for future benefit by using it regularly and vigerously - at least a few times a week. If you’re reading this, you’re not too young to start the deposit, no matter what gender. Use it or lose it seems to be increasingly a way of describing our entire physiological system, and that is certainly the case with our locomotive, protective, rather magnificent living skeletal system.
The Butt
Another topic posed by Jason was to write the next phase of the Bum as the Path to Sveltness . In that geekfit article i argued that since the butt hosts the largest muscle in the body, working it will have a big bang for the buck.

The Pistol and the Butt
As a preview to more descriptions of butt oriented effort, allow me to come back to the Issue i've been having with the Pistol. The pistol must be one of THE ULTIMATE butt working body weight moves, but i've been focusing on the weighted pistol. Adam gave me some great advice for slingshotting with a kb which i have tried with great pleasure and fried my legs too boot, and Irontamer David Whitely has volunteered to look at a video of my (pathetic attempt at) weighted performance. Rannoch suggested i look at Steve Cotter's Pistol DVD, and i owned a skepticism of any more sets of instructions. But then two things happened.

  1. after cold reflection i thought, my body weight pistols just suck too much: i don't "own" as the expression goes - the body weight pistol. So how get even heavier and do a weighted pistol. To me a weighted pistol is the bell is in the rack - not being used as a counter weight. Maybe no one else cares about that, but it's where i'd like to be. So i decided to get back to basics and focus on just getting more reps. back to the drawing board.
  2. i was at a recent event where the very rannoch recommended dvd was just sitting there, on sale. So dear reader, i bought one.
Another Pistol DVD?
Mastering the PistolWhat i am looking forward to doing is a detailed review of the dvd once i've had a chance to work through it to "master the pistol" - which by Steve Cotter's definition is 10 body weight pistols on each leg.

One may ask (as i did ) why one would need another Pistol DVD since there is already Pavel's most excellent Naked Warrior which teaches both the one arm push up and the pistol, and includes variants of each.

One may ask the same question about why would anyone do another kb instructional dvd after the excellent book/dvd "Enter the Kettlebell"? And this is rather the same question as why are there a dozen textbooks all teaching stats? Part of the answer may be that different teachers/writers/coaches convey the same topics in different ways, and at different times, different approaches may connect more effectively than at others.

Alternative Approaches
Right now, after working through some of the Cotter DVD, there is a certain appeal to the approach. Rather than working pistols by working the same move on progressively lower boxes, there are a series of supporting drills and levels in the DVD.

The DVD provides:
  • flexibility exercises
  • balance work
  • strength prep work
  • three levels of actual pistol practice prep
  • doing those 10/10 pistols
  • variations of pistols (including weighted)

Again, i'm not saying that one approach is better than the other. For my mental state right now, the Mastering the Pistol DVD seems a closer fit.

And here is where there may be a kind of philosophical difference between the two approaches. Cotter's focuses on drills and routines to build up the strength ultimately to execute the pistol as effortlessly as one might get up from a chair. In other words, the progression on the DVD implies that if you do all the preliminary levels, the end result will be the 10/side pistol.

Pavel's approach seems to be more about learning how to generate tension to succeed with movement. He does not quantify number of pistols done to master the move; rather he demos the types of moves that should be possible once the particular strength technique is mastered. The same technique is to be applied starting with the highest box necessary to do the move down to finally the fully in the hole bottomed out posture to do the move.

Naturally there is overlap between the two: Cotter uses progressively lower boxes as parts of his series, too, but again, there seems a philosophical difference especially with regard to the role of tension. That's not a bad thing; it's just different, and i think in a good way for me as a pistol trainee. I like more information.

To Boldly Go...
What i don't know is how Cotter developed his program, any more than i know how Pavel developed and tested his: did each of them test their approach out with 10 newbies to see what worked? Or did they just draw on their experience to say "this seems like a reasonable program to help build up the muscle skill necessary for this move." Dunno.

What i do know, is that, like having a couple texts on say statistics (and i have more than two because it's a topic that drives me crazy so the more insights i can get into ANOVA calculations the easier i breath) to get different material AND to get different perspectives on the same material, it seems there is much to learn from both.

So i'm flagging Cotter's program up as something that looks like an interesting plan to follow to build into the pistol - it even uses Adam's sling shot in level one (thought without the kettlebell :) ).

What it also confirms for me as i work through Level 2 is that, regardless of approach taken, it has been the right decision to get back to basics: to master the bodyweight pistol first - with perfect form for perfect reps (a focus in these moves) - before getting into the weighted variety. It may put off my Bete challenge, but c'est le gare.

This stepping back to perfect the bodyweight variant seems necessary. And as Pavel claims in the Naked warrior, doing the Pistol is a testament to strength, movement and agility, so why not get it right? Right now, it feels like Cotter's circling around and up to it program may be right for where i'm at.

I'll look foward to a more complete review when i'm done the progressions and see where that lands me relative to "mastery."
