the problem with "normal" weight-machines is that you never have the same resistance over the whole exercise, so the exercise is somehow "ineffective". you can also not precisely control the amount of power used, what can be dangerous in terms of reinjury when you pull too hard. so there is this computer-controlled high-tech-machine that regulates the resistance so you need all the time the same power to pull/push. it also releases the resistance when i apply too much power... nice safety-mechanism! funny stuff this machine! how about such things to train with for climbing related muscles???
AND AFTER TRAINING... ;)
