What is the Single-Arm Floor Press?

The single-arm floor press is a unilateral pressing exercise performed while lying on the floor. By using the ground for support, you create a stable base that provides clear feedback on your form. You press a single kettlebell with one arm while actively preventing your torso from rotating. The floor naturally limits the range of motion, stopping your elbow at a safe depth that builds strength without over-stressing the shoulder joint.

Benefits of the Single-Arm Floor Press

The unilateral load creates a significant anti-rotation challenge. As you press the weight, your body will want to twist toward the loaded side. Your core muscles, particularly the obliques, must work hard to keep your shoulders and hips flat on the floor. This builds anti-rotation strength that is crucial for stabilizing the spine during dynamic, real-world movements.

The floor press also minimizes shoulder impingement risk. By stopping the elbow at roughly 90 degrees of shoulder flexion, the movement avoids the deep, externally rotated position that can cause issues in a traditional bench press. This makes it an excellent choice for individuals with shoulder limitations or those looking for a joint-friendly pressing variation.

Functional Application

Real-world pressing is rarely symmetrical. Whether you’re pushing a heavy door with one arm, lifting yourself off the ground, or moving furniture, you often press with one side of your body while stabilizing with the other. The single-arm floor press directly trains this pattern, building unilateral strength and cross-body stability that transfers to everyday tasks. It also reinforces the fundamental pattern of getting up from the ground, a key indicator of functional independence.

Programming the Single-Arm Floor Press

• For Core Stability: 3 sets of 10-12 reps per arm. Focus on a controlled tempo and zero torso rotation.
• For Strength: 4 sets of 6-8 reps per arm with a heavier load.
• In an EMOM: Perform 4-5 reps per arm at the top of each minute for 10-12 minutes.

Load Selection: Start with a light to moderate weight. You should be able to complete all reps without your torso twisting or your hips lifting off the floor. A good starting point is a weight you can comfortably press overhead for 8-10 reps.

Execution:

1. Lie on your back with your knees bent and feet flat on the floor.
2. Position the kettlebell by your shoulder, with your elbow resting on the floor.
3. Extend your non-working arm out to the side at a 45-degree angle for balance.
4. Press the kettlebell straight up until your arm is fully extended over your shoulder.
5. Lower the kettlebell slowly until your tricep makes contact with the floor. Pause for a second before starting the next rep.

Journal of Strength and Conditioning Research, 21(4), 1271-1277. This study demonstrated that single-arm presses create significant activation in the contralateral core muscles (like the obliques) to resist rotation, highlighting the anti-rotation benefit of unilateral pressing.

This review supports using ground-based free-weight exercises with moderate instability (like a single-arm press) as a foundational method for training the core musculature.

Journal of Strength and Conditioning Research, 27(7), 1824-1831. This study found that using dumbbells and a less stable body position (standing vs. seated) increased neuromuscular activity in the shoulder muscles, supporting the principle that instability can enhance muscle activation.
