Quick takeaways

  • The analysis suggests that hypertrophy improves as proximity to failure increases, but other factors such as load and exercise selection also play a role in program design.
  • Proximity to failure at a given load does not have a meaningful impact on strength gains, as specificity of load is the primary driver.

Deep dives

Hypertrophy findings

The analysis indicates that hypertrophy improves as proximity to failure increases, with the best fit model showing a non-linear relationship. However, it's important to consider the limitations of the estimations made for proximity to failure and the uncertainty associated with the best fit curve. While the relationship is robust, the magnitude of the effect and the specific RIR values should not be overinterpreted. Positive outcomes can still be seen even at higher RIRs, indicating that proximity to failure is not the sole determining factor for hypertrophy. Other factors such as load, exercise selection, and individual differences must also be considered in program design.
