Prior to starting training to meet the BB physical requirements, I primarily just ran a bit and lifted weights. I was afraid that switching to more aerobic type resistance training (pushups, pullups, burpees) would result in my losing some muscle and strength gains. Now I only lift once a week and have been surprised to find that my overall strength has not declined and even improved a bit on some things like benchpress. Today was my lift day as I try to save my legs for tonight's Black Belt class at my local NJ school.
