Resting times between breaks of Reps.

For working out, it can get really tough. Through all of the tension and stresses of the muscle, a human needs a break. It is always good to take a little break between reps in a workout, but they should not last to long, or that can result in an improper workout and possible injury. This also depends on what kind of weights you are using, or how many reps you are doing. The more weight with less reps, the longer the break. With less weights and more reps you will need less of a break.
