Lie on your back holding the dumbbells in a neutral position (palms facing each other).
Keep your elbows close to your torso and your abdominals tight throughout the entire movement.
Your legs can be bent at the knees or straight during this movement; keeping your legs straight is more challenging because you create a purely upper body lift with no assistance from the legs.
Press the dumbbells straight into the air, reaching for the ceiling, and pause at the very top of the press.
Control the weight back down to your starting position, not letting the elbows slam back into ground. Repeat.
