High-load resistance training yields greater improvements in maximal strength compared to low-load training, although muscle hypertrophy can be achieved with a wide range of load intensities.
If your primary goal is maximizing maximal strength, prioritize high-load resistance training. However, if your goal is muscle growth (hypertrophy), you have flexibility and can achieve effective results with a wide range of load intensities, not just heavy weights.
GoodQualifiesHIGH confidence
Additionally, strength gains are notably greater with high-load compared to low-load training... This suggest that using heavy loads yields the greatest improvements in maximal strength, but muscle growth can be effectively achieved with a wide range of load intensities.

More from this paper
- Resistance training induces muscle hypertrophy primarily through increased muscle protein synthesis (MPS) mediated by mTORC1, resulting in a net gain of muscle protein when synthesis exceeds breakdown.Strong
- Combining resistance training with a high-protein diet (1.2–1.6 g/kg/day) significantly enhances muscle hypertrophy and strength gains compared to resistance training alone.Good
