NOTES:
Weekly set volume positively correlates with muscle growth. However, there are diminishing returns beyond approximately 12-20 sets per muscle group per week with regular weight lifting (Robinson et al. 2024). But what if we are using variable resistance? How many variable resistance sets do we need, as volume and intensity are inversely related? If one can intensify the fatigue on one set, might it be equivalent to more than one standard weight lifting set? Yes. Here is how the formula works. A study of X3 versus weight lifting observed that one X3 set, with multiple fatigue points in diminishing range, showed the muscle growth equivalent of THREE sets with regular weight lifting. (Connelly et al. 2024). And from a standard set count volume perspective, if rest times between sets are shorter than 90 seconds, then the volume must be doubled, and this would apply to the type of rest-pause sets that Westside Barbell uses with X3. (Krieger, n.d.) So as an example. If one were to do a chest press with X3, using full diminishing range, then two rest-pause sets after this, you would count that as the volume of 6 regular sets, the first X3 set counting for three regular sets, then the second and third mini-sets as 1.5 each for a total of 6.

Ultimately now we have a way to equate variable resistance with volume suggestions in non-high intensity studies. So its all the same amount of work, the difference being, how much time to you want to spend doing it, and if you choose an extended time (high volume training), how much work can you handle while still having glycogen in your musculature?
Always consult with your physician before undertaking any form of exercise/diet regime.
