I first saw this in the early 90s on a vhs. This was one of the films which got me inspired n pursue my profession of an instructor. Movies like these and Jackie Chan films were my staple diet during my growing days.
Revisited it recently n found this to be extremely dated out.
Those were the days when kung fu films used to have lots of sound/noises during a fight sequence.
We have trainers with wierd moustaches, wierd eyebrows n beards n funny ponytails.
The editing is a lil lousy.
After the initial fight scene it cuts abruptly. Then again during the last fight sequence it cuts abruptly.
Enoyed the training sequence those days but found it to be scientifically wrong n very lengthy now.
For the 1st chamber aka log rolling, strength, balance, and super fast footwork was required. Single leg squat wud have helped.
The space given was so less that there were chances of the head hitting the side walls.
Second chamber, dumbbell side/lateral raise was needed.
The training shown will definitely injure the rotator cuff big time.
For the 3rd chamber, more dumbell hammer curls n db reverse wrist curls were needed.
The training shown wud have caused carpal tunnel syndrome.
4th one was more of proprioception n eye coordination.
I don't advise the 5th one which is more like a football header n will cause neurodegenerative disease.
Szu-Chia Chen (horror film Hex) is there for few mins only.
