The dumbbell floor press limits the range of motion you would achieve with a regular dumbbell bench press, but still targets the chest, triceps, and anterior delts. This allows you to build strength in the top portion of the lift and work on strengthening the shoulder stabilizers.
Pressing from the floor with neutral grip can take the stress off the shoulder joint
Can overload and focus on strength in the top half of the press, as well as the lockout.
Takes your legs out of the movement, giving all the responsibility to your core and upper body to move the weight efficiently and build strength.
