1. Put your hands on the ground, shoulder width apart, and stand firm with your feet. Lift your chest and hips, and push up when your chest is about to touch the ground. This is equivalent to knocking down the gym.

Put your feet on the windowsill, and the rest of the movements are the same as above, which is equivalent to flattening the barbell in the gym.

3. handstand push-ups had better stick to the wall, and do it after having a certain strength to avoid injury, which is equivalent to pushing down.

In addition, you can't just practice your chest, you should cooperate with it:

Abdominal sit-ups (suitable for muscle enhancement) and skipping rope (highly recommended) are because almost everyone has certain abdominal muscles, but they cannot be displayed because of excessive abdominal sebum. Excess sebum is reduced, and abdominal muscles will naturally appear sit-ups to increase muscles.

Pull-ups (the most important thing) are not the most classic back exercises.

You can stay at home. I wish you success ~
