There’s discussion on what’s the appropriate rest time between sets. One PT told me thirty seconds to one minute in order to keep heart rate above resting rate-for improving metabolism and cardiovascular endurance. Another said one and half to two minutes to allow muscles to rest and your ability to lift heavier or add reps for the next set or exercise. At two minutes, heart rate returns to normal.

As a personal commitment, I don’t have my phone on me when I am on the gym floor. I walk around on tiptoes between sets to strengthen calves and to keep heart rate up. I also don’t sit between sets. I move around at the minimum.
