Strength and Physique

I was doing pushups tonight, and did 15 on my first set. Rested about 90 seconds, did another set and got 14 on my second, rested about another 90 seconds, then only got 10 on my last.  Why is it such a drastic drop? I notice this on a lot of my pressing exercises.  My Answer: This is actually normal.  What happens is that with higher repetitions, you accumulate a lot of lactic acid in your muscles.  This is the burning sensation that you feel.  The lactic acid interferes with your nerves, and as a result, you can't complete as many repetitions.  That's why there's a drastic drop in reps.  Once you hit that drastic drop in reps, it's time to stop performing that exercise.  More sets of that exercise just hamper muscle growth.

Alternate inverted rows with negative pull-ups.  This is where you prop yourself into the top position of a pull-up and lower yourself slowly, resisting the pull of gravity.
