This claim says that taking short breaks during sets or dropping weight between sets are useful training tricks for certain situations.
Evidence from Studies
Supporting (2)
Community contributions welcome
Rest-pause and drop-set training elicit similar strength and hypertrophy adaptations compared to traditional sets in resistance-trained males.
The study looked at the same training methods as the claim and found they work well for building strength and muscle, just like regular training, so it supports the idea that they are useful options.
Strength And Muscular Adaptations Following 6 Weeks Of Rest-Pause Versus Traditional Multiple-Sets Resistance Training In Trained Subjects.
This study shows that rest-pause training works just as well as regular training for building strength and even better for muscle endurance and size in some areas, so it supports the idea that it's a useful method.
Contradicting (1)
Community contributions welcome
The study shows that rest-pause training makes people jump worse and feel more tired right after, which suggests it might not be a good method if you need to perform well quickly.
