Their are great ways to develop power from
punching wall bag
explosive push ups and burpees
chin ups and pull ups
heavy bag and wall bag for conditioning and power...Get a heavy bag the weight of most of your opponents an eventually move up to 300....
Thats training...
The true way to gauge your power is to have a non-friendly competition where challenge someone like UFC or MMA...An if you can knock out most of your opponents then you have achieved knock out power...if you cant...then you dont go it...
To test rather or not you have a knock out power or killing power you have to first use it in real life...You know if you got heavy hands from actually fighting!
