Dumbbell One Arm Floor Press
Lie on the floor holding a weight to one side, foot flat on the floor on same side, opposite hand bracing against the floor.
Bend the elbow to bring the weight into the air, palm facing your torso.
Press weight to above your shoulder, straightening the arm, but not locking it out. Turn the palm to face south on your body. This is your starting position.
Lower the weight until your elbow touches the floor, upper arm at a max 45 degree angle from your body.
Press the weight up, punching at the sky above your shoulder.
If you need to rest, rest in the top position with your dumbbell above your shoulder.
