If you're already fit and lift weights, whether you do partial reps with the muscle stretched or full reps, you'll gain about the same tiny amount of strength after 12 weeks.

The effects of lengthened-partial range of motion resistance training of the limbs on arm and thigh muscle cross-sectional area

Randomized Controlled Trial

Human

The study compared two ways of lifting weights — one using a partial range and one using the full range — in people who already train regularly. After 12 weeks, both groups got about equally stronger, meaning neither method gave a clear advantage.

Similar Assertions

No matter the order of exercises, people who were already trained got much stronger after 12 weeks of lifting — all groups improved a lot.

Lifting heavy weights for 10 weeks makes you stronger, no matter how long you rest between sets or how many reps you do, as long as you’re lifting around 80% of your max.

If you're already strong and you train your back with either short or full movements on the lat pulldown machine for 8 weeks, you'll get just as much better at doing more reps with the same weight—no matter which style you pick.

If you're already strong and you train your back with partial pull-downs that stretch the muscle at the bottom, you'll get just as strong at doing full pull-downs as someone who does full movements the whole time — meaning stretching the muscle really hard might be more important than moving through the full range.

If you're already trained in lifting weights, whether you use free weights or machines, you'll get about the same strength gains after 8 weeks—as long as you're lifting the same amount, at the same intensity, and moving through the same range of motion.
