Bent Windshield Wipers With Top Leg Extension Tutorial
This abs exercise is a controlled core rotation performed on your back, combining bent windshield wipers with a top leg extension at each side. It helps train the obliques, deep core, and hip control while keeping the shoulders grounded. This movement is great for beginners who want a how to style introduction to rotational core work without equipment.
Focus on slow, smooth motion, keeping your ribs down and lower back controlled as the legs move side to side. This guide and tutorial will walk you through the correct technique.
Benefits
- Builds rotational core strength
- Improves control of the hips and pelvis
- Trains obliques without spinal strain
- Enhances coordination between core and legs
- Beginner friendly bodyweight movement
- Supports better posture and trunk stability
Setup & Starting Position
Lie flat on your back on the floor or mat. Extend your arms out to the sides at shoulder height with your palms pressing gently into the floor. These are your main support points and help keep your shoulders grounded during the movement.
Bend both knees to about 90 degrees and lift your feet off the floor so your hips and knees are stacked. Your thighs should be vertical and your shins roughly parallel to the ground. Keep your head relaxed on the floor, eyes facing up.
Before starting, gently brace your core by pulling your ribs down toward your hips and pressing your lower back lightly into the floor. This is your neutral base.
Setup tip: If your shoulders lift easily, move your arms slightly wider for more stability.
How To Do Bent windshield wipers with top leg extension (Step-by-step)
- Start lying on your back with arms out and knees bent, feet off the floor.
- Brace your core and keep both shoulders pressed into the floor.
- Slowly rotate your bent legs to the right across your hips.
- At the end of the rotation, extend the top leg straight while the bottom leg stays bent.
- Pause briefly with control, without letting the shoulders lift.
- Bend the extended leg back to return to the bent position.
- Use your core to bring both legs back to center.
- Repeat the same movement to the left side.
- One full rep includes the right side and the left side.
- Continue alternating sides with smooth, controlled tempo.
Form Cues
- Keep shoulders glued to the floor
- Move slowly and under control
- Extend only the top leg
- Ribs down, core tight
- No swinging or momentum
- Return to center with control
Breathing & Bracing
Breathing correctly helps you stay stable during this exercise. Before each rotation, take a small inhale through your nose to prepare. As you rotate your legs to the side, gently exhale through your mouth while tightening your abs.
Think about bracing as if you are lightly tightening a belt around your waist. Your core should feel firm but not rigid, and you should still be able to breathe. Avoid holding your breath.
A simple rhythm is inhale at center, exhale as the legs rotate and the top leg extends, then inhale again as you return to center. Keep the ribs down and pelvis steady throughout the movement.
Common Mistakes
- Letting the shoulders lift off the floor, press arms down harder to stabilize.
- Swinging the legs too fast, slow the tempo and use control.
- Extending both legs instead of just the top leg, focus on the cue.
- Arching the lower back, brace the abs and keep ribs down.
- Rushing the transition back to center, move smoothly.
How It Should Feel
Quick Self-Check:
Good signs:
- You feel steady tension in the abs and sides of the waist.
- Your shoulders stay flat on the floor.
- The movement feels controlled, not jerky.
Warning signs:
- Sharp pain in the lower back or hips, stop immediately.
- Neck strain from pressing the head forward.
If you feel this mostly in your lower back, reduce the range of motion or keep both legs bent without extending. If your neck feels tense, relax your head and widen your arms for support.

Sample Workout
Core Stability Workout
- Bent Windshield Wipers With Top Leg Extension, 3 sets of 8 to 10 reps
- Dead Bug, 3 sets of 8 reps per side
- Glute Bridge Hold, 3 sets of 20 to 30 seconds
- Side Plank Knees Down, 2 sets per side
Rest 45 to 60 seconds between sets. Focus on control rather than speed.
Progression Plan
Week 1: Perform 2 to 3 sets of 6 to 8 reps. Keep the movement slow and focus on keeping both shoulders down. Rest as needed and stop before form breaks.
Week 2: Increase to 8 to 10 reps per set and reduce rest time slightly. Add a one second pause when the top leg is extended to improve control.
Week 3: Slow the tempo further, taking 3 seconds to rotate to each side and 3 seconds to return. Maintain perfect control.
Move to advanced variations once you can complete all sets without losing shoulder contact or arching the back. Repeat a week if control is not consistent.
FAQ
How many reps should I do?
Start with 6 to 8 slow reps, where one rep includes both sides.
Can I keep my feet on the floor?
This changes the exercise and reduces core demand, it is better to keep feet lifted.
Why do I extend only the top leg?
Extending the top leg increases oblique engagement without overloading the lower back.
Is this safe for beginners?
Yes, when done slowly with shoulders grounded and controlled range.
Summary
Bent windshield wipers with top leg extension are an effective way to learn controlled core rotation using only your bodyweight. By focusing on slow movement, proper bracing, and shoulder stability, you build strong abs and obliques without unnecessary strain.
Use this exercise as part of a balanced core routine and progress gradually. Master control first, then increase difficulty when your form stays solid on every rep.
