Hollow Body Dual Kettlebell Floor Press

The hollow body dual kettlebell floor press is a variation of the floor press performed while holding two kettlebells and maintaining a braced hollow core position instead of resting the lower back flat with feet planted. Pressing from the floor limits shoulder range of motion compared to a bench press, reducing shoulder strain while still building chest, shoulder, and triceps strength. The hollow position removes leg drive and forces the core to stabilize the ribcage and pelvis throughout each rep, adding a stability component on top of the pressing work.

Muscles Targeted

• Primary: Pectoralis major, triceps brachii
• Secondary: Anterior deltoids
• Tertiary: Core stabilizers, rectus abdominis, obliques

Starting Position

Lie on your back on the floor with a kettlebell in each hand held at chest level, elbows resting on or near the floor and palms facing each other or slightly forward. Extend your legs out and brace your core so your lower back stays pressed into the floor, lifting your shoulders and head slightly to establish the hollow position before pressing.

Execution Steps

1. Set the hollow position by bracing your core, pressing your lower back into the floor, and lifting your shoulders slightly
2. Hold a kettlebell in each hand at chest height with elbows touching the floor as your starting point
3. Press both kettlebells straight up toward the ceiling, extending your arms fully without arching your back
4. Pause briefly at the top with the kettlebells stacked directly over your shoulders
5. Lower the kettlebells under control back to the point where your elbows lightly touch the floor
6. Maintain the hollow brace throughout every rep, not just at the start
7. Repeat for the desired number of repetitions

Form Cues

• Keep the lower back flat: Losing the hollow position and arching to press more weight defeats the purpose of the variation
• Elbows touch, don't bounce: Let the elbows lightly contact the floor at the bottom without relaxing or bouncing the kettlebells off it
• Press straight up: Keep the kettlebells traveling in a vertical line over the shoulders, not toward the head or hips
• Keep legs extended and together: This maintains the hollow lever and prevents using the legs to brace
• Breathe within the brace: Exhale on the press and keep the core engaged through the inhale rather than fully relaxing

Common Mistakes

• Letting the lower back arch to press more weight: This turns the exercise into a standard floor press and removes the core demand. Reduce the load until the hollow position holds throughout.
• Flaring elbows too wide: This shifts stress onto the shoulder joint. Keep elbows at roughly a 45-degree angle from the torso.
• Bouncing the kettlebells off the floor: This uses momentum instead of controlled strength and increases injury risk. Lower with control and pause briefly at the bottom.
• Uneven kettlebell paths: Pressing one arm faster than the other creates instability and uneven loading. Press both kettlebells at the same speed and to the same height.
• Holding the breath through the whole set: This limits core endurance and can spike blood pressure unnecessarily. Coordinate breathing with each rep instead of holding it for the entire set.

Variations

• Standard dual kettlebell floor press: Feet planted and knees bent, removing the hollow core demand for a more pressing-focused variation
• Single-arm kettlebell floor press: Unilateral version that adds an anti-rotation core challenge
• Dumbbell floor press: Same movement pattern using dumbbells for a more standard grip and bar path
• Hollow body barbell floor press: Same core-bracing concept applied with a barbell for heavier loading
• Alternating kettlebell floor press: Press one arm at a time while the other holds steady overhead, increasing time under tension

Tips for Progression

• Increase kettlebell weight in small increments once the hollow position can be held for the full set
• Add a 2-second pause at the top of each rep to increase time under tension
• Increase reps to 12-15 before progressing to heavier kettlebells
• Progress to a hollow body barbell floor press once dual kettlebells become easy to control

Training Notes

Program the hollow body dual kettlebell floor press 1-2 times per week as a pressing accessory movement, typically for 3-4 sets of 8-12 reps with 60-90 seconds of rest between sets. It fits well after a primary bench or overhead press movement, serving as a joint-friendly pressing exercise that also reinforces core bracing under load.
