Got out the Enter the Kettlebell Workbook today. I've wanted to do it for weeks, but never did. I'd make excuses.
I figured with trying to do Jiu-Jitsu 2 days a week, and Tang Soo Do 2 days a week, I'd be in better shape.
Day 1, 16 kg was enough to make me take breaks. I'll be repeating this week, that's for sure. Going to have to try and do it early in the morning before work. After work is just a little too hard.
