Myo Reps Calculator
Plan the activation set, short-rest mini-sets, effective reps, and stop point for a focused myo-reps sequence.
📌Myo-Reps Presets
Each preset fills a real myo-reps setup with exercise category, activation load, activation reps, RIR, mini-set size, mini-set count, rest breaths, and stop rule.

💡Myo-Reps Tips
Myo-reps training take one long set and breaks it into a cluster of mini-sets. Myo-reps training works because myo-reps training keep the muscles in tension without needing to take a rest between each sets. With myo-reps training, you will begin with an activation set.
The activation set is design to create fatigue in the muscles. Ensure that the activation set reach the point of muscle failure because if it does not, the myo-reps training will end up being similar to perform sets with short rests between them. The activation set is the most important part of myo-reps training because it primes the muscles to prepare for the mini-sets.
How Myo-Reps Training Works
The mini-sets will be the clusters of repetitions performed after the activation set. Instead of rest for two or three minutes between sets as is required of straight sets, you will only rest enough to take three to five breath between mini-sets. Taking these breaths will keep the metabolites in your muscles high, which will keep your muscles under stress.
The calculator will tell you how to structure your sets with the number of mini-sets and the number of repetitions you will do in each mini-set. The calculator will also use the category of the exercise because compound free weight will fatigue your body different than isolation cables exercises. The stop rule will tell you when to end your myo-reps training.
Once your repetitions drop by a certain amount or your repetition speed decrease, you will end your myo-reps training. If you continue past this point, you will be adding junk volume to your muscles that can potentialy lead to injury. The calculator will show you how many repetitions you will lose with the final set to ensure that your drop allowance for repetitions is realistic with the given load and exercise.
The load you use during myo-reps training is crucial to it’s success. Myo-reps training works best with moderate weight that allow you to perform approximately twenty repetitions with your activation set. If the load is too heavy, you will not have enough time to perform the mini-sets with your muscles not having reach failure.
If the load is too light, the muscles will not fatigue enough during your activation set. The reference tables on the page can help you find the best load for your exercises. Not all exercises are performed the same during myo-reps training.
Some exercises will allow you to perform more mini-sets with shorter breath counts between sets. This is because exercises like machine leg press will allow for more repetitions with less fatigue in your muscles. Exercises like the squat or the bench press will require longer breath counts to allow for the systemic fatigue in your muscles to dissipate and will allow for fewer mini-set to be performed.
To ensure that your results from myo-reps training are repeatable, you must use the same breath count throughout your training. If you take three breaths between the first and third mini-sets, you will not be performing your sets with repeatably. The consistency of the breath counts will allow you to compare the number of repetitions you can perform from one training session to the next.
It is important to separate the total number of repetitions from the effective repetitions in your myo-reps training. The activation set can require you to perform twenty-five repetitions, but only the last six or seven will be consider effective. These are the repetitions that create fatigue in your muscles.
The mini-sets will add to the number of effective repetitions because your muscles are already fatigue from the activation set. The calculator will separate these two to show you how many effective repetitions you are performing in total. Recovery is necessary after performing myo-reps training because the training creates more local fatigue than straight sets.
If you are performing myo-reps training three times a week on the same muscle group, you could potentially over-fatigue your muscles. Use the fatigue score generated from the calculator as a warning to ensure that you are not overdoing it with the muscle group you train. The main advantage of myo-reps training is that it allows you to perform a large amount of repetitions in a short amount of time.
Myo-reps training will allow you to reach the same amount of effective repetitions as performing forty-five minutes of straight sets. You will also not need to perform every set to failure. Myo-reps training allow you to increase the volume with the stop rule and breath counts.
