Barbell One Arm Floor Press
Barbell One Arm Floor Press Exercise Description
The Barbell One Arm Floor Press is a unilateral pressing variation performed on the floor to build pressing strength and control in the chest (pectoralis major), triceps, and anterior deltoid. Pressing one side at a time increases the demand on the shoulder stabilizers and the trunk to resist rotation, promoting balanced mechanics and awareness of bar path. The floor limits shoulder extension because the upper arm contacts the ground, which helps keep the shoulder in a safer, more controlled range compared with deep bench pressing. Expect a vertical forearm, a neutral wrist, and a slight elbow flare (about 30–45 degrees from the torso) for efficient force transfer. Because a single-arm barbell is inherently unstable, prioritize precise setup, a secure closed grip, and consistent tempo throughout the lift.

How To Do The Barbell One Arm Floor Press Exercise
‘- Set a rack so the bar rests above reach when lying down; use a spotter or safety bars.
– Lie supine with knees bent, feet planted, and eyes under the bar’s balance point.
– Slightly retract and depress the working-side scapula; keep ribs down and spine neutral.
– Grip the bar near its balance point with a full, closed grip; knuckles to the ceiling; wrist neutral.
– Place the nonworking arm on the floor out to the side for counterbalance and stability.
– Unrack with control, centering the bar over the mid-to-lower chest; forearm vertical.
– Inhale and brace; lower the bar until the upper arm lightly contacts the floor without bouncing.
– Keep the elbow angled 30–45 degrees from the torso; avoid flaring or tucking excessively.
– Press the bar straight up over the shoulder, reaching full elbow extension without hyperextending.
– Maintain square hips and shoulders; resist trunk rotation and bar sway.
– Re-rack with control, then switch arms using the same setup.
Barbell One Arm Floor Press Tips
‘- Set the rack so the bar rests just above your reach when lying down, and use a spotter or safety bars.
– Lie supine with knees bent, feet planted, and position your eyes under the bar’s balance point.
– Slightly retract and depress the working-side scapula while keeping ribs down and spine neutral.
– Grip the bar near its balance point with a full, closed grip and knuckles pointed to the ceiling.
– Keep your wrist neutral under the bar to maintain a stable, vertical forearm.
– Place the nonworking arm out to the side on the floor to provide counterbalance and stability.
– Unrack the bar with control and center it over the mid-to-lower chest with the forearm vertical.
– Inhale and brace before lowering the bar.
– Lower the bar until the upper arm lightly contacts the floor without bouncing.
– Keep the elbow angled about 30–45 degrees from the torso, avoiding excessive flaring or tucking.
– Press the bar straight up over the shoulder to full elbow extension without hyperextending.
– Maintain square hips and shoulders throughout, resisting trunk rotation and bar sway.
Barbell One Arm Floor Press Beginner Introduction
The Barbell One Arm Floor Press is a single-sided barbell press performed while lying on the ground, targeting the chest, triceps, and front of the shoulders. Because only one arm works at a time, the weight challenges the supporting muscles around the shoulder and the midsection, as the body resists tipping or twisting. This creates a pressing drill that not only builds strength, but also highlights any left–right differences in control or coordination.
During the exercise, the bar travels in a straight path over the chest and shoulder while the upper arm eventually meets the floor, naturally limiting how far the shoulder moves behind the body. This built-in stop encourages a more controlled range than deep bench variations. The bar is held with a secure, closed hand position and a steady rhythm, which helps refine balance and bar tracking. With the nonworking arm resting on the ground for support, the movement emphasizes stability through the torso, precise bar positioning, and smooth, deliberate reps on each side.
