Power lifting/muscle mass?

The aim of powerlifting is to lift as enough weight as possible on the three opposition lifts squats, bench presses, and deadlifts. Powerlifters aren't fundamentally concerned with how much muscle mass they have, provided their strength increases.

Assuming that you’re fairly new to lifting and not on drugs, you’d get the fastest progress training each body part at least twice a week, preferably 3x a week. Your muscles are only capable of growing for a maximum of about 48hours after a training session. If you only train a body part once per week, it will not grow for 5 days out of the week. If you train a body part more frequently, it will be growing constantly. Plus, the more frequently you perform an exercise, the better you’ll get at it and the stronger you’ll be. To get big, you HAVE to get strong.

Routines in which you train a body part once per week are for drug users who take drugs to allow their muscles to grow for longer after a training session and help them recover from the high volume. If you’re natural, you’d do much better with lower volume and high frequency.

You should follow a routine written by an expert like this https://forum.bodybuilding.com/showthread.php?t=15... or any other proven novice routine.

It would be better to focus on the compound movements of squats, deadlifts, bench press, overhead press and bent over barbell rows, and the assistance work for each.

Do three exercise each training session in either a push/pull/legs routine or another form of traditional powerlifting like the Starr model.
