Is 30 reps of a few dumbbell excercises heavy ? Most people call that semi aerobic.
I can barely manage 10 pushups on a 1' step for my arms, I am seriously weak. I hammer curl 30 lb, front curl 20 lb, and a few others with 15 and side lift 10lb and I can barely manage 10 reps in that, all the rest are 20-30 reps.
Most of that is done while walking.
Thanks.
Srinath.
