If you do the same total number of reps and sets, fancy techniques like drop sets or rest-pause won’t make your muscles bigger than regular training—your muscles grow the same no matter how you...

In trained young men, performing resistance training once or twice a week for 10 weeks with a fixed volume leads to little increase in muscle size and no improvement in strength, indicating that further progress may require a change in training approach.

Even if you tweak your weightlifting routine—like lifting heavier, doing more reps, or resting longer—it won’t make your muscles grow bigger than a simple, steady progress plan, even if your body is making more muscle proteins.

Adding stretching between your weightlifting sets can help you build more muscle faster than just resting normally, without making your workouts take longer. Research suggests this method can lead to about 10.5% more muscle growth compared to 6.7% with regular rest over two months.

For men who regularly lift weights, muscle growth and strength gains can happen whether they do 12 or 20 sets per week, suggesting that how hard and how consistently they train matters more than the exact number of sets.

For people new to weight training, doing more resistance exercises per week is linked to greater muscle growth. For those already trained, increasing the volume of training does not consistently lead to more muscle growth than lower volumes, suggesting that training history affects how muscles respond to increased workload.
