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.

Lifting heavier weights for nine weeks made young men stronger in a max lift test than lifting lighter weights, even when both groups worked until they couldn't do another rep.

Lifting heavier weights with proper form was better than lifting lighter weights for building both muscle strength and size in men after 3 months of training.

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.

Lifting weights at different effort levels (from light to heavy) all made muscles bigger and stronger in men over 12 weeks, but the lightest effort wasn't as good as heavier ones.

Even though your body releases similar growth hormones after light workouts whether you rest a little or a lot, you still get stronger and bigger muscles either way.
