A Humble Proposal: Factoring Percentage of Reps Into Reps In Reserve Calculations
RPE (ratings of perceived exertion) and RIR (reps in reserve) can be useful training tools for some sports where the goal is to train to failure or near failure, but there is no catch-all number that works for all exercises. Generally, RPE is used for managing heavy efforts of weight or reps, and not for exercises where training to failure or near failure would inhibit the continuation of training like working on endurance for running a marathon. Instead of static numbers, RPE/RIR can function as a percentage of total effort to be applied to a wider range of workouts.
The Rest Period Broscience Is Wrong
The old-school belief is that we needed to vary rest periods depending on how strength or endurance focused we wanted our adaptations to be, as well as how much metabolic stress we want to provoke. Recent research suggests otherwise.
No Load Exercise Part 3 - Bands, TRX, Endurance, and BFR.
In the past, I've covered what no load exercise is, and how to use it. However, I haven't covered how to transition out of it, or other tools you can use to get an effective workout while working around injury. One of the most useful options is exercise bands, which are easier on the joints.
