Lifting very heavy weights a lot might raise the chance of getting hurt for fit men, because in one study, some guys got knee and shoulder injuries and had to stop, while others lifting lighter weights didn't get hurt.

Lifting heavy weights with fewer reps and longer breaks might cause more joint injuries than lifting lighter weights with more reps and shorter breaks, especially in young men who are already fit.

This study looked at two types of weight training for young men who already lift weights. It found a small hint that powerlifting-style training might help build more squat strength than bodybuilding-style training over 8 weeks, but the results aren't clear enough to be sure—bigger studies are needed.

If you do heavy weight training for eight weeks, your thigh muscles get stronger—no matter if you use a special band to restrict blood flow after your workout or not.

Lifting heavy weights with longer breaks between sets makes young men stronger faster than lifting lighter weights with shorter breaks, based on an 8-week study.

Drop sets don’t make you stronger than regular sets if you’re lifting moderate weights — but we don’t know if they’d work better or worse if you lifted really heavy weights.
