But I'll still be burning out on 20 reps? Won't that trigger more muscle fibers?
I just know I built a decent chest in 8th grade only from push-ups lol.
trigger them, but through which energy pathway? mpk stress of contractile proteins from bodyweight exercises is only half-achievable at a sarcoplasmic stimulus range if you're extremely untrained and/or extremely heavy. otherwise, it won't even make a dent.
