Peripheral Fatigue
Peripheral fatigue occurs within muscles from metabolites, glycogen depletion, or damage, reducing force and often causing soreness.
Peripheral fatigue happens inside the muscle—metabolite buildup, glycogen depletion, or micro-damage—making fibers unable to produce expected force. It drives soreness, swelling, and weak reps late in sets.
Nutrition, sleep, and gentle blood flow aid recovery.
