I am currently doing the explosive strength training journey and had a quick question. I was given a strength interval with 4 exercises and low reps (5 sets). However, the rest time was only 50 seconds. Is this not too short a rest time for a strength based interval. I was under the impression that strength intervals should have longer rest time (i.e approx 2 minutes or until heart rate normalizes) otherwise it would be training more endurance. Can anyone give some advise on this?
