Looks like we missed some direction, but we’ll be updating it.
It should tell you to take working sets to failure. Studies show that taking sets to failure is almost exponentially better than leaving a bunch of reps in reserve.
So if you’re doing a high rep set, but taking it to failure, they’ve seen similar gains in hypertrophy and even strength.
So the intensity between a 5 rep set and a 25 rep set should be the same if taken to failure.
One issue with high rep sets though is that you might end early because of pain rather than true muscular failure.
But if you’re lifting something 5 times that you could lift 10, then I’d just call that a warm up and wouldn’t count that in working sets.
