Alternating Floor Press
The alternating floor press has you lying on your back with your knees bent, a kettlebell in each hand at your chest, pressing one arm up at a time while the other stays fixed. It trains the chest as the primary mover with the shoulders and triceps assisting, and because your upper arms rest on the floor at the bottom of each rep, it naturally limits the range of motion in a way that's easier on the shoulders than a bench press.
Why it works
The floor stops your elbows the moment your upper arms touch down, which caps the range of motion at a point that's comfortable for most shoulders, unlike a bench press where the arm can travel further behind the torso. Pressing one arm at a time on top of that adds a core stability challenge: as one kettlebell drives upward, your trunk has to resist twisting toward that side, working your obliques and deep core muscles continuously throughout the set, something a two-arm press doesn't ask for nearly as much.
Set up
- Lie on your back on the floor with your knees bent and feet flat.
- Hold a kettlebell in each hand at chest height, upper arms resting on the floor.
- Brace your core lightly before the first press.
How to do it
- Press one kettlebell straight up until your arm is fully extended.
- Keep your core braced to resist your torso twisting toward the pressing side.
- Lower that kettlebell back down with control until your upper arm touches the floor again.
- Press the other arm up as the first one finishes lowering.
- Continue alternating sides at a steady, controlled pace.
- Keep your hips and shoulders square to the floor throughout the entire set.
Form cues
- Upper arm touches down each rep.
- Core braced against the twist.
- Press straight up, not toward center.
- Hips and shoulders stay square.
Breathing: Exhale as you press each kettlebell up, inhale as it lowers back to the floor.
Common mistakes
Letting the torso twist toward the pressing arm.
Fix: Brace your core before each rep and keep your hips flat on the floor; if you can't resist the twist, the load is too heavy for this variation.
Slamming the upper arm down onto the floor instead of controlling the descent.
Fix: Lower each kettlebell with control, letting the upper arm touch down gently rather than dropping.
Pressing the kettlebell toward the center of the body instead of straight up.
Fix: Keep the press path vertical over your shoulder; drifting inward reduces stability and control.
Rushing the alternating rhythm and losing tension in the resting arm.
Fix: Keep the resting kettlebell steady and controlled at chest height rather than letting it wobble while the other side presses.
How to program it
- Two sessions a week of 3 sets of 8 to 10 reps per arm is plenty to start, since this is still real pressing load on the shoulder even with the floor limiting the range; add a third day only if nothing else in your week loads the chest or shoulders.
- It works well as a shoulder-friendly alternative to the bench press, or as a core-focused pressing variation later in a session.
- Progress the load only once every rep can be completed without any torso twist.
- Pairs well with a pulling exercise like a row in the same session to balance pushing and pulling volume.
Safety notes
- The floor naturally limits shoulder range, which makes this a reasonable choice for anyone whose shoulders are sensitive to a full bench press range.
- Choose a weight your core can control without twisting; a rotating torso under load can strain the lower back.

Frequently asked questions
What muscles does the alternating floor press work?
The chest drives the press, with the shoulders and triceps assisting to lock out the elbow. Because only one arm presses at a time, the core also works continuously to resist your torso twisting toward the loaded side.
Floor press vs bench press: what's the difference?
The floor limits how far your upper arm can travel behind your torso, which caps the range of motion at a shoulder-friendly point. The bench allows a longer range but places more demand on the shoulder joint at the bottom. Many people use the floor press specifically because it feels easier on the shoulders.
How many reps of the alternating floor press should I do?
Eight to ten reps per arm, for 3 sets, is a solid starting point. Focus on keeping your torso square throughout rather than chasing a high rep count.
Why does my torso twist during this exercise?
This usually means the kettlebells are heavier than your core can currently stabilize against. Reduce the weight and focus on bracing your abs before each press until your hips and shoulders stay flat on the floor throughout the set.
