1. When preparing posture, pay attention to the body facing the equipment and put your feet in the middle of the pedal.

2. Abdomen and chest, legs are balanced.

3. Lower it gently in a controllable way to avoid the heavy block vibrating the base and damaging the instrument.

4. Knee flexion should not be less than 90 degrees, otherwise it is not conducive to leg extension and knee injury.

5. When descending, the thighs should not be too close to the body, so as to avoid overstretching the gluteal muscles and hamstring muscles, which is not easy to start with force, and it will also oppress the chest and abdomen and affect breathing.

6. Always keep your legs parallel, do not open or shake, and do not twist your body.
