Advanced resistance training systems do not produce a statistically significant improvement in muscle hypertrophy compared to traditional multiple-set training in recreationally trained adults aged 18–45, with a pooled effect size of g = 0.046, indicating that muscle growth is primarily driven by total volume, intensity, and effort rather than set structure.

When you lift weights, your muscles grow bigger mainly because of how much total weight you move and how hard you push yourself — not whether you do regular sets, drop sets, or rest-pause sets. Studies show that as long as the total volume and effort are the same, advanced training methods don’t make your muscles grow any larger, because the key signals for growth — sustained force on muscle fibers and buildup of metabolic by-products — are already fully activated by traditional training. The only thing advanced methods change is how strong you get, not how big your muscles become.
