Full range of motion (fROM) resistance training yields trivial to small advantages over partial range of motion (pROM) for overall muscle hypertrophy, strength, power, and body composition outcomes.

For most people, full range of motion is the best default for building muscle and strength because it offers a slight edge. However, the difference is small. If you have an injury that hurts at full depth, partial range of motion is still highly effective and better than nothing. If you are a powerlifter or sport-specific athlete, train the specific partial ranges relevant to your sport, as strength gains are specific to the angle trained.
