In Martial Arts? The thing is you can cultivate more power unironically when you are younger than an older person, this is a fact. Younger people generally have much stronger capabilities than the older people. You can look up statistics yourself. You reach your peak around 20-25 years old athletics wise then at 30 upwards its downhill from there, your maximum reps and strength possibilities just down spiral.
