The Claim

In physically active males, resistance training with constant intensity (8RM) and varied exercises results in greater strength gains compared to resistance training with varied intensity (6–10RM) and constant exercises, suggesting that exercise selection has a greater impact on neural adaptation than intensity fluctuations.

Cause and effect
1 study reviewed
In plain English

In physically active men, changing the exercises during strength training while keeping the weight constant leads to greater increases in strength than changing the weight while keeping the same exercises.

See the scientific wording

Resistance training with constant intensity (8RM) and varied exercises produces greater strength gains than training with varied intensity (6–10RM) and constant exercise, indicating that exercise selection may be more critical than intensity fluctuations for neural adaptation in physically active males.

Why this might work

When a person performs different exercises with the same weight, their nervous system learns to coordinate muscles more efficiently across multiple movement patterns. Each exercise stretches and loads muscle fibers in unique ways, activating different parts of the same muscle that were not fully used before. This repeated, varied stimulation trains the brain to send stronger and more synchronized signals to the muscles, allowing them to produce more force without needing to grow larger.

  1. Study: Changes in Exercises Are More Effective Than in Loading Schemes to Improve Muscle Strength

    Changing which exercises you do (like switching from squats to lunges) helped people get stronger faster than changing how heavy the weights were while doing the same exercise. So, mixing up movements beats changing weights for building strength.
