What are the methods and precautions for using a leg stretcher?

The basic steps for using a leg stretcher are as follows:

1. Adjust the device. Adjust the seat height according to individual height and leg length to ensure comfortable support for the legs during movement.

2. Prepare posture. Sitting on a leg stretcher, place your ankles behind the mat, press your feet against the mat, and hook your toes. Sit straight, with your hips and lower back tightly against the seat cushion, raise your head and chest up and tuck in your abdomen, and hold the grip on the edge of the seat with both hands.

3. Stretch. When exhaling, use the quadriceps muscles to extend the legs to the maximum extent possible, keeping the rest of the body stationary and keeping the legs straight for 1 second. When inhaling, slowly lower the weight to the starting position, ensuring that the calf does not exceed a 90 degree angle.

4. Repeat the action. After completing a set of training, adjust the weight and training plan as needed, pay attention to controlling the movement speed, and ensure stable and controlled movements.

In addition, when using a leg stretcher, the following precautions should also be taken:

1. Ensure weight balance between the left and right feet, avoid knee injuries, and try not to lock or fully extend the knees when stretching your legs.

2. When pushing the platform away, the knees should remain slightly bent.

3. Warm up before use to prevent strain.

4. After use, pay attention to safety and etiquette, and do not litter or occupy other people's space.
