One Arm Barbell Floor Press

🎯 Chest, Triceps🏋️ BarbellIntermediateCompoundShoulders (2°)

How to do the one arm barbell floor press

  1. Lie flat on your back with your knees bent and your feet firmly on the floor.
  2. Draw in your abs and contract your lats, and glutes.
  3. Have your partner hand you the bar and with your bicep parallel to the floor lift and extend your arm fully so it is straight.
  4. Return to the starting position.
  5. Complete reps and switch arms.

Muscles worked

Two muscle groups share the work: the pectoralis major, which drives the upper arm forward and across the body and the triceps brachii, which straightens the elbow, and through its long head helps pull the arm back at the shoulder.

Because more than one joint is moving, the work does not stay in one place: the deltoids stabilise the shoulder and add force at the top of the range.

How this movement works

The working muscles shorten as they drive the load away from you, and more than one joint changes angle to do it. Load spreads down a chain instead of sitting on one muscle, which is why a compound push handles more weight than any single-joint alternative — and why joint position, not the muscle, is usually what fails first.

It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.

What you need

A barbell locks both hands to one bar, so neither side can drift and the load climbs in plate-sized steps. That makes it the simplest way to add weight and the least forgiving thing to bail out of.

Difficulty

Listed at intermediate level. It assumes you already own the underlying pattern and can hold position under load — if the position breaks before the target muscle tires, drop back to a beginner variation until it does not.
