One Arm Floor Press
Also works: Chest · Shoulders
A floor press done with one arm holding a barbell at its centre, palm turned in toward your torso. The floor stops your elbow before the chest can stretch, so the triceps finishes the rep — and balancing a long bar on one hand turns the whole thing into an anti-rotation drill for your trunk.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Use a lighter bar if the gym has one. A 20 kg Olympic bar balanced at its midpoint on one hand is already a serious ask before you add a single plate.
- Lie on your back with knees bent and feet flat, close enough to the rack or your partner that the handoff is short.
- Take a neutral grip at the exact centre of the bar, palm facing your torso, and have a partner hand it over — do not attempt to clean it into place yourself.
- Press the free hand flat into the floor beside you and push down through it to anchor that side of your ribcage.
- Set the bar directly over your shoulder joint, not over your face or your sternum.
Every rep
Breathing & tempo — Inhale on the way down, hold the brace through the pause, exhale hard as you lock out. Two seconds down, a one-second pause with the elbow on the floor, then press at speed.
Before you load it
- Always take a handoff and give the bar back to a partner at the end of the set. There is no safe way to bail a loaded barbell held in one hand while lying on your back.
- Stop the set the instant the far end of the bar starts tipping. A bar that rotates out of your palm falls on your head or your ribs, not on the floor.
Sets, reps & load
Where to start, and what to change when it stops being hard.
Start with an empty bar — 20 kg on one hand at the balance point is a full working set for most people. Six controlled reps per arm with 30 kg total is a solid intermediate marker. Add 2.5 kg only when both arms hit the top of the range with the shoulder blades flat and the far end of the bar dead level.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Press the free hand hard into the floor and squeeze that side's glute. If the ribs still twist, cut the load by a third — you are training rotation, not pressing.
Start with the bar alone and add no more than 5 kg at a time. One arm on a long lever will not hold anything close to half your two-hand bench.
Rest the elbow, count one full second, then press. If the pause makes the weight impossible, the bounce was doing the work.
Chalk or tape the exact midpoint and set your little finger against the mark every rep. Re-check it after the handoff — the bar usually shifts a few centimetres as it changes hands.
Why bother
Pressing from the floor removes the bottom third of a bench press. Your elbow lands before the shoulder reaches full extension, which cuts the stretch on the chest and hands the lockout to the triceps. That short, top-half range is exactly where most bench presses stall, and training it directly pays off.
Loading one side of a 2 m barbell puts a rotational torque through your torso that a dumbbell simply does not. Your obliques and lats have to fight the bar tipping and your ribcage twisting off the floor, all while the pressing arm balances a long lever on one hand. Half the difficulty here is not in the triceps at all.
Where it fits
Accessory work on a pressing day, 3 sets per arm, after your main bench. Be clear-eyed about it: a one-arm dumbbell floor press trains the same range with none of the balance circus. Use the barbell version when you want the anti-rotation demand or when the dumbbells in your gym stop at 30 kg.

Asked and answered
Why not just use a dumbbell?
For most people, you should. A one-arm dumbbell floor press trains the same shortened range with none of the balance problem. The barbell version exists for two reasons: the long lever adds a real anti-rotation demand through your trunk, and it lets you load past whatever your gym's heaviest dumbbell happens to be.
Does the floor press build a bigger bench?
It builds the top half of one. Stopping at the floor removes the stretched position where the chest does most of its work and concentrates the effort on the triceps-driven lockout. If you fail your bench near the chest, this is the wrong fix; if you stall mid-range, it is a good one.
How far should my elbow travel out from my body?
About 45 degrees from your ribs. Tucked hard to the side shortens the range and grinds the elbow; flared to 90 degrees puts the shoulder in the position it least likes under a one-sided load. Split the difference and keep it there for every rep.
Should the palm face in or forward?
In, toward your torso. The neutral grip is what makes a single hand on a long bar controllable at all, and it keeps the shoulder in a friendlier position. A pronated one-arm barbell press is a party trick, not a training movement.
