Following our discussion on Rate of Perceived Exertion (RPE), another equally valuable method to manage training load and optimize performance in CrossFit is Reps in Reserve (RIR). RIR, like RPE, is a self-regulated training tool that focuses on quantifying how many repetitions an athlete feels they could still perform before reaching muscular failure. Integrating RIR into CrossFit workouts can complement RPE usage, aiding athletes in achieving precise training intensities for maximal gains.
Reps in Reserve (RIR) is a concept that asks athletes to estimate the number of possible repetitions remaining in a set before they cannot perform another rep with proper form. It's important to remember these are quality-focused reps that are being quantified intrinsically. For example:
This method is highly effective in strength training, where managing fatigue and understanding one's limits are crucial for progressive overload without injury.
RIR allows athletes to adjust the weight or scale of an exercise according to how many reps they feel they safely have left in the tank. This tailoring can lead to better management of workout intensity and volume, crucial in a varied sport like CrossFit.
Using RIR can help prevent overtraining by ensuring athletes do not push to failure too often, which can be taxing on the nervous system and require longer recovery times.
While RPE measures effort and exertion, RIR provides a more specific measure related to fatigue and capacity. Both methods can be used together for a nuanced approach to training—RPE for assessing overall exertion and RIR for managing specific set and rep schemes. Pairing these efforts can improve your set-to-set efforts, leading to greater consistency and greater gains in the long term.
Incorporating RIR into CrossFit involves a few practical steps:
Reps in Reserve (RIR) is a powerful tool that complements Rate of Perceived Exertion (RPE) in fine-tuning the intensity and volume of CrossFit workouts. By integrating RIR into your training regimen, you can enhance both the safety and efficacy of your workouts, leading to sustained improvement and peak performance.
