Qi/Chi is real. it's a bioelectrical energy. can it shoot out hadouken's and the king i can't spell it wave from dragonball z - no. but there is something flowing in our body

can it add to a punch's power? i believe so, but it takes a lot of cultivation/time that may or may not be better spent on lifting weights or kettlebells

ultimately it's up to the martial artist/athlete/fighter to decide. in the west, most people have been brainwashed to think of qi/chi as dragonball z energy blasts, but it's not.
