Do muscle micro-tears really cause muscle growth? 🤔 @MuscleandMotion

Uploaded April 2026 | Updated September 2026, 2 weeks ago

For years, many believed that muscle damage and micro-tears were the main drivers of hypertrophy. But research paints a different picture.

Muscle growth is primarily driven by mechanical tension, though metabolic stress can also contribute. 💪
In other words, soreness and muscle damage are not the goal of training.

$FRACTIONAL SETS 🤯 Are you actually counting your sets correctly? You log your chest sets during the bench press, but what about your triceps? A new meta-analysis by Remmert et al. highlights that during every compound lift, such as the bench press, shoulder press, or dips, the triceps play a meaningful role. They are not the primary movers, yet they still contribute enough to influence your total training volume. In other words, you might be training your triceps without even noticing. This is where the concept of Fractional Sets becomes important, as described in the paper: 👉 Direct set = an exercise that directly targets the muscle 👉 Fractional set = indirect work from a compound lift (approximately half a set) This matters because counting both direct and indirect work helps you reach the weekly training volume that actually drives results. What the researchers recommend: 💪Aim for 8-12 fractional sets per session to maximize hypertrophy, as gains tend to level off around 11 fractional sets. This doesn’t mean all sets must be fractional; combining direct and fractional work also works. For example, 5 direct sets + 6 fractional sets (equal to 3 full sets) give you 8 effective sets. ⚡For strength, about two direct sets per session appear sufficient before benefits begin to diminish. 🎯Match the exercise to the goal, since muscles respond differently to direct vs. indirect work.
