Lying Reverse Dumbbell Fly
Take the dumbbells and lie down on the bench. Place your legs wide to ensure good stability.
Lower your arms with dumbbells so that the palms look at each other. Bend them slightly and freeze in this position. Inhale and start raising the dumbbells to the sides.
Only your shoulder joint moves, keep a little angle in the elbow. When you feel that the chest muscles are already starting to stretch, lift the dumbbells even further.
Mistakes and Recommendations:
If you bend your arms, it means that the dumbbells are too heavy for you. Try to take lighter ones. Be careful, too heavy weight may hurt you!
You may round your chest in the lowest position of the movement. It increases the amplitude. But do not raise your shoulder blades!
