You don’t think his time between sets should relate to the number of reps he’s using? He didn’t say what rep range he’s doing.
Personally I think if he’s using a rep range of 7 or greater, waiting too long (3+ minutes) between sets would defeat the purpose of that set. On the other hand if your talkng about 3 rep sets where your just worried about power, waiting 5 minutes may be good. Also mix it up time and range occasionally.
5 minutes might be ok, but I can see anything longer as too long. While he wants to do the most weight at competition or at a particular time, when training you don’t want to burn yourself out using a weight that it takes you 5 minutes to recover from week after week after week.
For the Ryan Kelly reference, I say this Powerlifters like to stress their heavy sets, with long ass rest periods but when you look at the true elite and their logs alot of them have hypertrophy type warm ups that most people tend to overlook. I remember seeing one guy’s log, I don’t remember who, and he did a set of 40 with a decent weight.
50 huh? Hope your using steroids…J/k. But you may seriously want to consider how often you go heavy (for your joints) I’m sure training at 50 is different than 20.
Sure, the amount of time needed to recover is going to change with different rep ranges and depending on how taxing the set was. But, if his main goal is strength (performance based), then I assumed that he was talking about using fiarly low reps. Even if he’s using a moderate rep range, or even a high rep range, I don’t see any problem in him waiting as long as he needs to maximize his performance.
