Windshield Wipers With Bent Legs Tutorial
Windshield wipers with bent legs is a controlled core exercise performed on your back, rotating your bent legs side to side while keeping your shoulders grounded.
It targets your obliques and deep abs, helping improve core strength, trunk rotation control, and lower back stability.
This move is best for intermediate exercisers who already have basic core control and want a guided way to build rotational strength. Focus on slow movement, steady breathing, and keeping your upper body relaxed against the floor.
Benefits
- Builds rotational core strength
- Improves oblique control and symmetry
- Challenges deep abdominal stabilizers
- Supports healthier trunk rotation mechanics
- Enhances body awareness and coordination
- Can help protect the lower back when done with control
Setup & Starting Position
Start by lying flat on your back on a comfortable surface such as a mat. Bend your knees to about a 90 degree angle and lift your feet off the floor so your shins are roughly parallel to the ground.
Extend your arms out to the sides at shoulder height, palms facing down. This wide arm position increases stability and helps keep your shoulders grounded throughout the movement.
Press both shoulders gently into the floor and let your neck relax. Your head should rest naturally on the mat, eyes looking upward.
Bring your knees together and stack your hips in a neutral position, not tilted forward or backward.
Quick setup tip: Before starting, lightly tighten your abs as if bracing for a cough, this helps protect your lower back from excessive twisting.
How To Do Windshield wipers with bent legs (Step-by-step)
- Lie on your back with arms stretched out to the sides, palms down.
- Bend your knees and lift your feet so your hips and knees are flexed.
- Brace your core and press your shoulders into the floor.
- Slowly rotate both knees together toward the right side.
- Lower only as far as you can control without your shoulders lifting.
- Pause briefly near the floor while staying tight through your abs.
- Exhale and bring your legs back to the center.
- Repeat the rotation to the left side.
- Continue alternating sides with smooth, steady tempo.
- Finish the set by returning to center and placing your feet down.
Form Cues
- Keep shoulders heavy on the floor
- Move slow and controlled
- Knees stay bent and together
- Abs tight, ribs down
- No swinging or momentum
- Control the return to center
Breathing & Bracing
Breathing correctly during windshield wipers with bent legs helps maintain control and protect your spine. Begin each rep with a gentle inhale through your nose while your legs are centered.
As you rotate your knees to one side, lightly brace your abs, think of tightening your midsection without flattening your breath. You should still be able to breathe, not hold it.
Exhale slowly as you bring your legs back toward the center. This exhale helps engage your deep abdominal muscles and regain control.
A simple rhythm to follow is inhale at center, brace and rotate, exhale returning to center. Keep your ribs down and pelvis steady throughout. If your breathing becomes rushed, slow the movement and reduce range until you regain control.
Common Mistakes
- Letting the shoulders lift, fix by widening your arms and reducing range.
- Swinging the legs fast, fix by slowing the tempo.
- Arching the lower back, fix by bracing your abs before moving.
- Separating the knees, fix by lightly squeezing them together.
- Going too low too soon, fix by limiting depth to what you control.
- Holding breath, fix by using a steady inhale and exhale pattern.
How It Should Feel
Quick Self-Check:
You should feel a steady burn through your obliques and deep abs as your legs move side to side. Your core should feel engaged and supportive, not strained.
Good signs:
- Controlled movement with no jerking
- Shoulders stay flat on the floor
- Even effort on both sides
Warning signs:
- Sharp pain in the lower back or hips, stop immediately
- Neck tension or shoulder lifting
If you feel it mostly in your lower back, reduce the range of motion and tighten your abs more before rotating. If your neck tenses up, relax your head and press your shoulders down.
Alternative Names
bent-knee windshield wipers, bent leg windshield wipers
Variations
Easier
- Partial range bent-knee wipers, rotate only halfway to build control
- Feet lightly touching floor, tap one foot down for extra support
Harder
- Straight-leg windshield wipers, extend legs fully for more leverage
- Paused bent-leg wipers, hold near the floor for 2 to 3 seconds
Sample Workout
Core Control Workout:
- Dead bug, 10 reps per side
- Windshield wipers with bent legs, 8 to 12 reps total
- Side plank, 20 to 30 seconds per side
- Glute bridge, 12 to 15 reps
Rest 45 to 60 seconds between exercises. Complete 2 to 3 rounds. Focus on slow, clean reps rather than speed.
Progression Plan
Week 1: Perform 2 to 3 sets of 6 to 8 total reps, alternating sides. Focus on slow tempo and limited range. Rest 60 seconds between sets.
Week 2: Increase to 8 to 12 total reps per set. Add a brief pause near the bottom of each rotation. Keep shoulders fully grounded.
Week 3: Extend sets to 12 to 16 total reps or reduce rest to 30 to 45 seconds. Aim for smoother transitions and stronger bracing.
Once you can control every rep without shoulder lift or back strain, you may progress to straight-leg windshield wipers. If form breaks down, repeat the previous week and refine control.
