空气自行车

A full-body cardio machine that challenges both upper and lower body in high-intensity efforts or steady-state conditioning.

Instructions:

1. Sit on the seat and adjust height so your knees are slightly bent at the bottom.

2. Grip the handles firmly and place feet on the pedals.

3. Push and pull with your arms while pedaling with your legs.

4. Keep your back tall and core engaged throughout.

5. Maintain pace or alternate sprints and recovery based on the goal.

Common mistakes:

• Relying only on legs (no arm push/pull)

• Slouching forward with poor posture

• Sprinting without pacing in long efforts
