I personally enjoy doing a set of 8. When I say I reach a new PR(bench or squat or DL) I usually just mean that I can finally do 8 reps of it. I could probably do pretty damn heavy weights if I did 1 rep max but I wonder: is it just a vanity thing like “look how much I can lift for 1 single rep” or is it actually something to help me increase my mass? Or would a 5 rep increase mass more?
It’s worth a try for me, I have been consistently going to the gym 2-4 days a week and I take a good monohydrate Creatine with plenty of water throughout the day. Whenever I do feel a bad rep/overly sensitive soreness, I take a 3 day break minimum. I’ll try some of the 1RM bench next time, I’ve actually not tried my 1RM for bench in months, it’s probably pretty decent by now
