@backnforth I prefer sets across and the last set is as many as possible. It's the simplest way and there is no overthinking or cheating with RIR. If I'm doing 3x8 and my last set I hit 8 reps or more then the next week I increase the weight.
@dearlyloved A bad night of sleep means the next day I will be weaker in the gym. Not sure how much it matters long term since I've never been a good sleeper and still made plenty of gains in the gym.
