For me, resting only one minute between sets for the same muscle group cause a massive dropoff in weight or reps. If I take a set to around failure and rest only minute, I can barely perform half the amount of reps I did in the previous set. To keep the rep amount the same, I have to reduce the weight by around 30%. Doing this does give a crazy pump and a ton of metabolic stress on the muscle, but I feel like it sacrifices load (weight) immensely.
Did they actually train with that little rest?
