"At first I didn’t think Max-Stim would make any difference at such a low weight but it actually did. Had I done a straight 20 reps I would have slowed down toward the end as I got tired but in this case I was able to keep the concentric speed as fast on the last rep as the first." It is an amazing technique. "I wasn’t sure about the timing of the M-Time so at first I tried counting but that was screwing up my rep count." Yes, sometimes I have trouble with that as well. Once the weight starts getting heavy, I have better luck watch the clock.
