Re: Resting between reps - is it necessary?
You should be resting 1 to 1.5 minutes between SETS, not reps. No rest period between REPS unless you need at adjust your grip or change weight.
Try and take about 8-10 seconds to complete each rep. 2-4 seconds on the "push" or "pull" part of the rep, hold 1 second at the "top," then 4 seconds on the return to the starting point. Wait about one second and then start your next rep.
If you are spending more time resting between sets than you are completing the reps, you are lifting too fast... slow down and maintain proper form.
