Wall training is a simple and effective training method without equipment, which can help strengthen the chest muscles. Here are some ways to practice chest muscles with walls:

1. wall push-ups: stand about one arm away from the wall, put your hands shoulder-width on the wall, and bend your legs slightly. Bend your elbows and lean forward to do push-ups.

2. Push the wall: stand about one arm away from the wall, stick your arms straight on the wall, and bend your knees slightly. Bend your elbow slowly, move forward, and then straighten it again.

3. Wall sit-ups: Sit close to the wall with your knees slightly bent. Lean back, let your upper back and head land, and then slowly put away your body until you sit up straight.

Wall training can not only exercise chest muscles, but also abdominal muscles, back muscles and buttocks. These training methods need some time and practice to master, but they can be practiced anytime and anywhere without any equipment, which is very convenient.
