Less then a month from the worlds doing 3reps seems excessive imo...but hey I'm not his coach and I was just asking.
The sport is about lifting 1RM, not 3 singles with short rests. Would you have a thrower do 3 throws in short succession less then a month out from competition to improve their 1RM?
I agree through repetition of heavy lifts it will strengthen the body, but heavy singles would be more suited, not 3 heavy singles with short breaks. Why not have 3-4mins break and go heavier?
