The Advantage of an Office Door: A Work Up for a Carb Up
Yes work up: i am working up to a happy feeding time, knowing i'm not just eating cuz i'm a bit peckish; i'm refurbishing my muscles glycogen stores when they'll be happiest to receive them.
To achieve this today, i decide to do a 15:15 vo2max workout as per Viking Warrior Conditioning (reviewed here).
But then, mid workout, what happens? i start to feel a callus go - for those of you who do this kind of thing you know what i mean. I don't want a tear - i'm about to go away on a break and while i suppose that would be the ideal time to have a tear (if one must) i think i'd rather not. Band aids etc, no fun. Phooey.
So i do the a-typical smart thing and stop my vo2max work with a 12kg and transition gracefully into an on-the-fly adapted 8on 12 off session of swings for the next 11 minutes with a 24kg. Perfect form, perfect form. Every rep a perfect rep. My word, 12 secs post kettlebell seems much shorter post a kettlebell set than it does on the bike.
This protocol is based on one developed by Trapp and co for eliciting optimal fat burn in women of both athletic and not so athletic backgrounds. 20mins of 8/12 intervals seemed to be a sweet spot for fat burning.

The metabolic response to two different forms of high-intensity intermittent cycle exercise was investigated in young women. Subjects (8 trained and 8 untrained) performed two bouts of high-intensity intermittent exercise: short sprint (SS) (8-s sprint, 12-s recovery) and long sprint (LS) (24-s sprint, 36-s recovery) for 20 min on two separate occasions. Both workload and oxygen uptake were greater in the trained subjects but were not significantly different for SS and LS. Plasma glycerol concentrations significantly increased during exercise. Lactate concentrations rose over the 20 min and were higher for the trained women. Catecholamine concentration was also higher postexercise compared with preexercise for both groups. Both SS and LS produced similar metabolic response although both lactate and catecholamines were higher after the 24-s sprint. In conclusion, these results show that high-intensity intermittent exercise resulted in significant elevations in catecholamines that appear to be related to increased venous glycerol concentrations. The trained compared with the untrained women tended to show an earlier increase in plasma glycerol concentrations during high-intensity exercise.
As for the application of the above with a heavy kb, i can say after the 11th minute, it seems i may have found a way to test for a new max heart rate. Cuz that was higher than on a bike and not maximal. I was still standing. Hmm. On the fat loss, well i don't know. It's more effortful than on a bike. May try again with a 20kg, just to calibrate. Interesting enough to want to give it a go again.
Feeling very pleased to have done this work up.
Clean up; re-dress and regroup. Lunch becomes a happy happy thing. A definite re-fuel. Ideally if i'd been thinking straight i would have grabbed a lighter bell just to do some more cool down swings to get a bit more fat flamed off before it re-esterfies from sitting down again.
So what's the take away here:
- glad i've FINALLY gotten to a place where i can change an envisioned workout in order to keep working out, rather than obsessively have to stick with ONE routine because, who's keeping track again? oh? just me? right-o.
- doing short intervals with a heavy kb is an intriguing workout from both a cardiac and potential fuel burning perspective.
- remember to stash chalk at work, too: a few more minutes and that 24 would have been sailing out of the office towards the new building. Even though that's rather a pleasant thought - sort of like shooting a canon at an enemy battlement, the consequences would not be pretty.
- the snatch grip to avoid calluses in fast repeats is a skill to be learned - still
