Swimmer Kicks
Swimmer Kicks Exercise Description
Swimmer Kicks (prone flutter kicks) are a bodyweight hip-extension drill performed face down, using alternating leg kicks to emphasize the posterior chain. The primary movers are the gluteus maximus and hamstrings, with the gluteus medius/minimus and deep hip rotators stabilizing the pelvis. The spinal extensors work isometrically to maintain a neutral spine while the hips generate motion. The goal is to lift and alternate the legs from the hips—not the low back—using a small, controlled range that keeps the pelvis quiet on the mat. This pattern helps reinforce clean hip extension mechanics and lumbopelvic control while avoiding excessive lumbar extension.

How To Do The Swimmer Kicks Exercise
‘- Lie prone on a mat. Stack your hands and rest your forehead on them. Legs long, hip-width, kneecaps pointing straight down.
– Set your trunk: lightly brace the abdomen and keep ribs and hip bones heavy to the mat to maintain a neutral spine/pelvis.
– Engage the glutes. Without arching your lower back, lift both legs a few inches by extending at the hips; keep knees straight and ankles neutral.
– Begin alternating small kicks from the hips: as one leg rises, let the other lower. Keep the movement smooth and within a short range.
– Keep the pelvis square and still—no rocking. Think “long through the legs,” not “high.”
– Maintain a relaxed upper body with the neck in line and shoulders down away from ears.
– Breathe continuously; avoid breath-holding or bracing so hard that you tilt the pelvis.
– Lower both legs with control to finish, keeping the spine neutral throughout.
Swimmer Kicks Tips
‘- Keep your kneecaps pointing straight down and legs hip-width to start.
– Lightly brace your abdomen so ribs and hip bones stay heavy on the mat.
– Focus on lifting from the hips, not arching your lower back.
– Keep knees straight and ankles neutral as you lift and kick.
– Use a small, controlled kick range so the pelvis stays quiet on the mat.
– Think about reaching long through your legs rather than kicking high.
– Keep your pelvis square and still—avoid any rocking side to side.
– Relax your upper body, keeping your neck in line and shoulders down.
– Breathe continuously and avoid bracing so hard that your pelvis tilts.
Swimmer Kicks Beginner Introduction
Swimmer Kicks (prone flutter kicks) are a bodyweight floor exercise centered on hip-driven leg movement while lying on the front of the body. The upper body rests on the mat while the legs stretch out behind, moving in a small, alternating kicking pattern. The motion comes mainly from the hips, so the glutes and hamstrings take the lead, with the sides of the hips helping to steady the pelvis. Muscles along the back support a natural spine position while the legs move.
This drill highlights controlled hip extension rather than a big lift or dramatic arch through the lower back. The kicking range stays modest, with the pelvis resting calmly against the mat and the legs reaching long behind the body. The trunk stays quiet and relaxed, especially around the shoulders, neck, and ribs, while the legs share a smooth back-and-forth rhythm. Steady breathing and a gentle sense of support through the middle of the body round out the pattern, reinforcing hip mechanics that favor stability through the lower back and pelvis.
