The Sitting Swimmer on a Chair mimics freestyle swimming arm strokes while seated, targeting the deltoids (lateral and rear heads) and rotator cuff with support from the upper back. Because it requires no equipment and keeps the spine supported, it is well suited to beginners, desk workers, and anyone rebuilding shoulder mobility or strength after time off.
Cómo hacer el Sitting Swimmer on a Chair
- 1Sit upright on the edge of a chair with your feet flat on the floor, hip-width apart, and your spine tall — no leaning on the back rest.
- 2Draw your shoulder blades back and down, engage your core lightly, and rest both arms alongside your body.
- 3Raise both arms forward to roughly shoulder height, palms facing down, as your starting position.
- 4Begin the stroke: sweep your right arm down and back alongside your hip while your left arm arcs forward and overhead in a smooth, continuous arc.
- 5Reverse the motion so your left arm sweeps back and down as your right arm arcs forward and overhead — this completes one full cycle.
- 6Continue alternating arms at a controlled tempo, keeping your torso still and your hips square to the front.
- 7Breathe steadily throughout — exhale as each arm sweeps back, inhale as it arcs forward.
- 8After completing your target reps or time, slow to a stop and lower both arms to your sides.
Consejos de técnica
- Keep your torso completely still — the movement lives entirely in your shoulders. Any rocking or rotating shifts load away from the deltoids.
- Extend each arm through its full arc, from overhead to alongside the hip, to engage the entire range of the deltoids and rotator cuff.
- Move deliberately and resist the return: slowing the arc down on both the forward and backward phases doubles the time under tension.
- Keep your shoulder blades gently retracted throughout to activate the rear deltoids and avoid impingement at the top of the arc.
- If you feel pinching at the top of the arc, reduce the overhead reach slightly until shoulder mobility improves.
Errores comunes
- Shrugging the shoulders toward the ears during the upswing, which transfers the work to the upper traps and reduces deltoid engagement.
- Rocking the torso side to side with each stroke, which reduces shoulder loading and adds unnecessary stress to the lower back.
- Rushing the movement and relying on momentum rather than muscular control, turning the exercise into a swing instead of a strength drill.
- Letting the elbow bend excessively on the sweep, which shortens the lever arm and reduces the training stimulus on the shoulder.
- Starting with too fast a tempo before the rotator cuff is warmed up, which risks impingement or strain in a stiff shoulder joint.
Preguntas frecuentes
What muscles does the Sitting Swimmer on a Chair work?
The exercise primarily targets the lateral and rear heads of the deltoid along with the rotator cuff muscles. The upper back (rhomboids and lower trapezius) assists in keeping the shoulder blades set, and the core engages to stabilize the torso throughout.
Is the Sitting Swimmer on a Chair good for beginners?
Yes — it uses only bodyweight, requires no equipment beyond a chair, and removes spinal loading by keeping you seated. It is a practical starting point for building shoulder endurance and control before progressing to loaded overhead work.
How many sets and reps should I do?
For general shoulder conditioning, 2–3 sets of 15–20 alternating strokes (roughly 30–40 total arm movements) works well. You can also work by time — 30 to 45 seconds per set — to build endurance. Rest 30–60 seconds between sets.
What is a good alternative to the Sitting Swimmer on a Chair?
Seated front raises and seated lateral raises isolate the deltoids with a similar setup. Standing swimmer exercises add core demand, while resistance band pull-aparts target the rear deltoid through a different arc.
Where should I feel the Sitting Swimmer on a Chair?
You should feel a steady burn in the side and back of your shoulder (lateral and rear deltoid) and mild effort in the upper back. If you feel sharp pinching in the front of the shoulder, reduce the overhead range of motion and check that your shoulder blades remain retracted.
