Do you suffer from a lot of hand tears in training? If so, in addition to working on your technique and not being sloppy about programming, I heartily recommend three products to you for 2011 to keep you hand-healthy and in the game:
#1) Callous Shaver - $5
Even if your kettlebell technique is flawless, if you have callous build-up, snatches with a heavy bell is going to pull on the skin. Keeping your callous build-up under control will go a long way to avoiding tears.
2) Chalk - less than $5 a block
I've spoken with a lot of RKCs who eschew chalk, but here's the thing: friction + moisture = blisters, and blisters WILL tear. Work on your technique, do lots of reps, and use chalk to keep your hands dry. You don't have to cake layers of it on - a little will go a long way.
3) Burt's Bees Shea Butter Hand Repair Creme - $10
Use this at night before you go to bed - your dry hands will thank you.
