The Swimmer is a prone bodyweight exercise that targets the glutes, hip extensors, and lower back (erector spinae) by alternating opposite arm and leg lifts from a face-down position. It builds posterior-chain strength and spinal stability with minimal joint stress, making it an effective low-impact option for improving hip extension and core control.
How to do the Swimmer
- 1Lie face-down on the floor with your legs straight and your arms extended overhead, palms facing down. Keep your forehead lightly resting on the floor or hovering just above it.
- 2Engage your core by gently drawing your navel toward your spine, and squeeze your glutes slightly to stabilize your pelvis.
- 3Simultaneously lift your right arm and left leg a few inches off the floor, keeping both limbs straight. Hold for a brief moment at the top.
- 4Lower your right arm and left leg back to the starting position under control.
- 5Immediately lift your left arm and right leg in the same controlled manner, mirroring the movement on the opposite side.
- 6Continue alternating sides in a steady, rhythmic flutter — like a swimming motion — for the desired number of reps or duration.
- 7After completing your set, bring your hands under your shoulders, press up, and sit back into a child's pose to release tension from the lower back.
Form tips
- Keep your head in a neutral position aligned with your spine — looking straight down at the floor helps prevent unnecessary neck strain.
- Breathe steadily throughout: exhale as you lift each pair, inhale as you lower. Holding your breath increases unnecessary tension.
- Prioritize controlled, deliberate movement over speed or height — small, precise lifts with full muscle engagement beat wide, sloppy swings every time.
- Focus on lengthening the lifted limbs away from your center rather than simply raising them; this maximizes glute and lower-back activation.
Common mistakes
- Lifting the limbs too high by arching the lower back excessively, which compresses the lumbar spine and shifts the work away from the glutes and hip extensors.
- Cranking the head upward to look forward, which strains the cervical spine and disrupts the neutral alignment needed for safe posterior-chain work.
- Moving too fast and relying on momentum instead of muscle control, which reduces time under tension and diminishes the strength and stability benefits.
- Letting the core go slack between reps, which allows the pelvis to rock side to side and puts uneven stress on the lower back.
- Bending the knees or elbows during the movement, which shortens the lever arm and reduces the load on the target muscles.
Frequently asked questions
What muscles does the Swimmer exercise work?
The Swimmer primarily targets the glutes and hip extensors along with the lower back (erector spinae). Because you are lifting from a prone position with no equipment, these posterior-chain muscles must work against gravity to raise and hold each arm and leg.
Is the Swimmer exercise good for beginners?
Yes. It requires no equipment, uses a low range of motion, and places minimal stress on the joints, making it accessible for beginners. Focus on slow, controlled reps and keep the lifts small until you build enough core stability to maintain a neutral spine throughout.
How many reps or sets should I do for the Swimmer?
A common starting point is 2–3 sets of 10–15 alternating reps per side (20–30 total lifts), or time-based sets of 20–30 seconds. As the movement becomes easier, increase volume or slow down the tempo rather than rushing through extra reps.
What is the difference between the Swimmer and the Superman exercise?
The Superman lifts both arms and both legs simultaneously, creating a static hold that demands more spinal extension. The Swimmer alternates opposite arm and leg in a flutter pattern, which adds an anti-rotation stability challenge and more closely mimics real movement patterns. Both target the posterior chain, but the Swimmer tends to be more dynamic and rhythmic.
Can the Swimmer exercise help with lower back pain?
When performed with proper form, the Swimmer can strengthen the muscles that support the lumbar spine, which may reduce the risk of lower back discomfort over time. However, if you are currently experiencing acute lower back pain, consult a healthcare professional before adding this or any prone exercise to your routine.
