Dumbbells, barbells, gym equipment and so on. Actually, I don't need any equipment to exercise my chest. I have equipment at home, but I don't need it. 3 to 5 groups of standard push-ups, each group doing 10 to 20, each group resting 1 min. Through the last flight of stairs are: key push-ups, lever push-ups and so on. Focus on push-ups means that one hand should be placed on an object as high as a blue ball, and the other hand should do push-ups normally. The lever push-up assistance is that one hand is placed on the ground and the other hand does push-ups normally. With the improvement of physical strength, I will recover my physical strength by going up a flight of stairs.
