To adjust a knee extension machine, you primarily need to adjust the range of motion and the seat to align your knee properly with the machine's axis.
Here's a breakdown:
- Adjust the Range of Motion: Set the starting point of the exercise (how far back your leg bends).
- Adjust the Seat: Position the seat so that your knee lines up with the axis (pivot point) of the machine. This ensures proper mechanics and reduces the risk of injury.
