The Claim
In novice lifters, training three times per week with at least three minutes of rest between sets results in similar levels of strength gain and muscle hypertrophy when comparing different repetition schemes (4x4 versus 3x8–12).
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.
For people new to weight training, lifting weights three times a week with at least three minutes of rest between sets leads to comparable increases in muscle size and strength whether they use heavier weights for fewer reps or lighter weights for more reps.
See the scientific wording
When training frequency is three times per week with at least three minutes of rest between sets, different repetition schemes (4x4 vs 3x8–12) produce similar strength and muscle hypertrophy outcomes in novice lifters.
When you lift weights with enough rest between sets, whether you use heavy weights for fewer reps or lighter weights for more reps, your muscles experience enough pull and buildup of metabolic byproducts to trigger the same internal signal that tells muscle cells to grow stronger and bigger.
What the research says
1 studyWhen people lift weights three times a week with enough rest between sets, doing heavy lifts with fewer reps or lighter lifts with more reps both help you get stronger in about the same way.
