[Dumbbell incline push to exercise the upper edge of the chest muscles] Adjust the stool to about 30 degrees with the ground, lie on your back on the stool, hold dumbbells in both hands, and the two dumbbells can be close together to maintain balance. 1. Turn your wrists, bend your elbows, open your shoulders, and slowly lower the dumbbells to fully stretch the chest muscles, but make sure you can continue to control the dumbbells. 2. Use your chest to exert force, lift the dumbbell until your arms are straight, and squeeze inward until the dumbbells touch each other, one up and one down.
