Function Description
The primary function of the G7-S72 is to provide a controlled and effective workout for the hamstrings through a seated leg curl exercise. Users sit on the machine, position their legs against the pads, and then curl their legs backward against resistance provided by a weight stack. The design emphasizes proper biomechanics to ensure efficient muscle engagement and reduce the risk of injury.

- Weight Selection: Users are instructed to exercise using no more weight than they can safely lift and control. The selector pin must be completely inserted into the weight stack.
- Controlled Exercise: Exercises should be performed in a controlled manner, and the weight should be returned to its fully-supported start position.
- Safety Stops: If applicable, safety stops should be set to the appropriate height.
- Stability: The manufacturer recommends securing all stationary Matrix strength equipment to the floor to stabilize it and eliminate rocking or tipping over. This should be performed by a licensed contractor. If the equipment is not secured to the floor, resistance straps, ropes, or other means should never be attached, nor should the equipment be used for support during stretching, as this may result in serious injury.
- Rep Counter: The machine includes a rep counter, and users are reminded to remove the insulating sheet when installing it.
