• SS-31 + endurance training: why volume tolerance increases?

Better mitochondria mean less burnout overall

Energy lasts longer during hard sessions

Cells recover faster between endurance efforts

Muscles stay fresher deeper into workouts

More ATP means longer sustainable training

Recovery keeps pace with endurance volume

Recovery keeps up with training volume

Training feels sustainable not draining anymore

Volume climbs because fatigue ceiling rises

Energy systems stop falling apart early

Long sessions stop wrecking recovery

Training load feels easier to absorb

System feels supported not stressed

Work capacity climbs without extra strain
