Floor Press

The floor press is much more difficult that a normal bench press for many reasons:

• It is not a common exercise technique and thus not well practiced nor taught.
• Because of it's simplicity it's been around much longer than the popular bench press.
  
• Floor press : Bench press :: Deadlift : Back squat. Normally for a bench press or back squat you would start the lift in the eccentric phase of the contraction, or the stretching of the muscle, and end with the more difficult part of contracting the muscle, also known as the concentric phase. Floor presses and deadlifts start with concentric (hard) part and end with the eccentric (easier)
  
• The range of motion is as if you were in the midpoint of a normal bench press.

Try it.
