Incline dumbbell press:
Pick up the dumbbells off the floor using a neutral grip (palms facing in). Position the ends of the dumbbells in your hip crease, and sit down on the edge of an incline bench. To get into position, lay back and keep the weights close to your chest. Once you are in position, take a deep breath, and press the dumbbells to lockout at the top. Slowly lower the dumbbells under control as far as comfortably possible (the handles should be about level with your chest). Contract the chest and push the dumbbells back up to the starting position. Keep your back in the neutral position.
Before increasing the load, learn to perform the exercise in the right way.
Do not use inertia. Control all your movements.
Do not arch your back too much. Natural arching is enough.
Keep the distance between the dumbbells at the top position (about 15 centimeters).
Exhale when you lift the dumbbells.
