Nice stuff. I'm currently doing calisthenics every day for the last month. I was going to the gym prior to this for 6 months. I gain at least 6 pounds of muscles. I've begun to incorporate the sort of conditioning that you are doing in the recent days. I've been wanting a steel brush for a long time. So far I'm just kicking a steel pole and it's pretty brutal even with super small kicks. Now I want one steel brush more than ever.
