The Claim
In young adult males, resistance training with matched volume produces significant muscle hypertrophy (≥4.7%) regardless of whether it employs high-load/long-rest or low-load/short-rest protocols, demonstrating that multiple training methods can effectively stimulate muscle growth.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If young men lift weights with the same total effort—whether they use heavy weights with long breaks or light weights with short breaks—they’ll still grow about the same amount of muscle. So, different ways of lifting can both work.

What the research says
1 studyStudy: Effects of rest intervals and training loads on metabolic stress and muscle hypertrophy
Both heavy lifting with long breaks and light lifting with short breaks made guys’ arms bigger, as long as they did the same total amount of work. So yes, different ways of lifting can build muscle just fine.
