I put in 5 days at the Martial Arts Academy this week, going just a little too long between rest days. It's a learning process, and I've resolved to take rest days a little more frequently.
I seem to be making progress in a variety of areas, from skill to weight loss. I've made it up to 30 sit-ups now, which is easily twice what I was able to manage a few weeks ago. And I'm making similar progress with push-ups, stretching, and other routine exercise elements.
My buddy Jay, who just got his kung fu green belt, wants me to get my taekwondo black belt so he can "kick my ass". We'll just see about that.
