So what would be the "recommended" maximum rest time between sets or exercises? How much is bad and how much is good?
As they told me here, how much time you rest between sets/exercises doesn't affect hypertrophy/strength or whatever it may be. If that's so then it would never make sense to take less time to make your sets more "intense", given that you'll gain the same whether you train intensely or not and whether you take more time or not.
