Muscle Building Routine

I am a novice to Karate. I started Practicing Shorin-Ryu Karate about 9 months ago. I was grossly over weight when I started. At 41 years old, I was about 285 pounds. But I was good at denial. I thought I was strong, I thought I was healthy, but I wasn’t. I didn’t realize this until I signed my children up at karate and I was watching some of the young and old students at the dojo exercising.
