With traditional strength training equipment, once you've completed the lift you're left in the dangerous position of having the full weight in the air - usually above your head. If you're lifting near your personal maximum, you may not have sufficient engergy left to bring the weight down safely. This is why Olympic lifters step out from underneath the weight after a lift and let it drop, and also why having a spotter when performing a bench press is a great idea. In Cormax equipment, it's all about the patented safety cylinder. This cylinder will prevent the weight from crashing down on you after your lift.
