Surprising Findings
Pre-exhaustion didn't enhance target muscle recruitment despite the common belief it increases muscle activation.
It contradicts fitness influencers who promote pre-exhaustion for muscle growth, especially since EMG activity stayed the same.
Practical Takeaways
Skip pre-exhaustion if you're new to strength training—focus on compound exercises without extra fatigue to maximize reps and progress.

Doing single-muscle exercises first makes you tired, so you can build muscle with lighter weights on bigger exercises.
Doing a pullover exercise before a rowing exercise doesn't make your back muscles work harder than if you just did the rowing exercise by itself, at least for people who aren't trained.
When people who don't exercise much do a special warm-up called pre-exhaustion before rowing exercises, their shoulder muscle gets tired faster than if they didn't do the warm-up.
When people new to weight training exercise, their back and arm muscles show signs of getting tired over time, no matter how they warm up.
When people who don't exercise regularly get tired out before doing certain workouts, they can't do as many repeats afterward—about 25% fewer.
