Twisted Leg Raise: Core Form, Benefits, Sets, Tips & FAQ

Core Strength

Twisted Leg Raise

Intermediate Bodyweight Lower Abs / Obliques / Core Control

The Twisted Leg Raise is a controlled floor-based core exercise that combines a lying leg raise, a small hip lift, and a subtle pelvic twist. Because the legs move together while the hips rotate slightly at the top, the exercise challenges the lower abs, obliques, and deep trunk stabilizers. Keep the movement smooth, keep your lower back controlled, and focus on lifting and twisting from the core instead of swinging the legs.

This exercise works best when each repetition is slow, compact, and deliberate. First, the legs rise from the floor with control. Then, the hips lift slightly as the pelvis rotates to one side. Finally, the legs lower back down without dropping or arching the lower back. As a result, the movement trains both abdominal flexion and rotational control in one sequence.

Although the Twisted Leg Raise looks simple, it becomes challenging when performed correctly. Therefore, avoid rushing the top position. Instead, pause briefly, rotate with control, and return to center before lowering. This helps the abs and obliques stay active through the full repetition.

Safety note: Stop the exercise if you feel sharp lower-back pain, hip pinching, neck strain, or uncontrolled pressure through the spine. Keep the range smaller until your core can control the movement.

Quick Overview

Body Part	Core
Primary Muscle	Lower abdominals, especially rectus abdominis with posterior pelvic control
Secondary Muscle	Obliques, hip flexors, transverse abdominis, and deep core stabilizers
Equipment	No equipment required; optional exercise mat
Difficulty	Intermediate, because the twist requires core control and lower-back stability

Sets & Reps (By Goal)

Core control: 2–3 sets × 8–10 reps per side with a slow tempo.
Lower-ab strength: 3–4 sets × 10–12 total reps with a controlled hip lift.
Oblique focus: 3 sets × 8–12 alternating twists, pausing briefly at each side.
Beginner progression: 2 sets × 6–8 reps with bent knees and a smaller twist.
Core finisher: 2–3 sets × 12–16 total reps after your main ab exercises.

Progression rule: Add reps only when you can lower your legs without arching your back. After that, increase the pause at the top or slow down the lowering phase.

Setup / Starting Position

Lie on your back: Start on a flat surface with your legs extended and your body aligned.
Place your arms down: Keep your arms beside your body or slightly out to the sides for balance.
Brace your core: Gently pull your ribs down and press your lower back toward the floor.
Keep your legs together: Squeeze the legs lightly so they move as one unit during the raise.
Relax your upper body: Keep your neck, jaw, and shoulders relaxed throughout the movement.

Tip: If your lower back lifts too early, bend your knees slightly. This reduces leverage and makes the exercise easier to control.

Execution (Step-by-Step)

Start from the floor: Keep your legs together and begin with your lower back controlled. Before you lift, brace your abs as if preparing for a gentle punch.
Raise both legs: Lift your legs upward in a smooth arc. Keep the motion controlled, and avoid kicking the legs up with momentum.
Reach the top position: When your legs approach vertical, slightly lift your hips off the floor. This small hip lift turns the movement into a stronger lower-ab contraction.
Add the twist: Rotate your pelvis slightly to one side while keeping your legs together. The twist should come from the waist and hips, not from swinging the feet.
Return to center: Bring your hips back to the middle with control. Then prepare to lower the legs while maintaining abdominal tension.
Lower slowly: Lower your legs toward the floor without letting your lower back arch. Stop before you lose control, then begin the next repetition.
Alternate sides: On the next rep, twist to the opposite side. Continue alternating until all reps are completed evenly.

Form checkpoint: The twist should be small and clean. If your legs swing sideways or your lower back lifts aggressively, reduce the range and slow the tempo.

Pro Tips & Common Mistakes

Pro Tips

Move slowly: A slower raise and lower phase increases core tension without adding load.
Twist from the pelvis: Think about lifting one hip slightly higher than the other at the top.
Keep the legs connected: When the legs separate, the movement becomes less stable and less precise.
Use the floor as feedback: Your lower back should stay controlled, especially during the lowering phase.
Breathe with control: Exhale during the lift and twist, then inhale as you lower.

Common Mistakes

Swinging the legs: Momentum reduces abdominal tension and may stress the lower back.
Twisting too far: A large twist often shifts tension away from the abs and into the hips or spine.
Arching the lower back: This usually means the range is too large or the legs are too straight.
Pulling with the neck: Keep your head relaxed and avoid lifting the shoulders off the floor.
Dropping the legs: The lowering phase should be controlled because it builds eccentric core strength.

FAQ

What muscles does the Twisted Leg Raise work?

The Twisted Leg Raise mainly works the lower abs and obliques. In addition, the hip flexors assist the leg raise, while the transverse abdominis helps stabilize the trunk during the twist.

Is the Twisted Leg Raise good for lower abs?

Yes. Because the exercise includes a leg raise and a small hip lift, it strongly challenges the lower-ab region. However, the lower abs work best when you control the pelvis instead of swinging the legs.

Should beginners do this exercise?

Beginners can do a modified version with bent knees and a smaller twist. However, if the lower back arches or the hips feel uncontrolled, it is better to master regular lying leg raises first.

Why do I feel this exercise in my hip flexors?

Some hip flexor involvement is normal because the legs are lifting. Nevertheless, your abs should control the pelvis. To reduce hip flexor dominance, bend your knees slightly and focus on curling the hips upward at the top.

How do I make the Twisted Leg Raise harder?

You can make it harder by slowing the lowering phase, pausing longer at the top, keeping the legs straighter, or adding ankle weights. However, only progress when your lower back stays stable.

How do I make the Twisted Leg Raise easier?

Bend your knees, reduce the twist, lower only halfway, or place your hands slightly wider on the floor for more support. These changes help you keep better control while still training the core.

Recommended Equipment (Optional)

Exercise Mat — provides cushioning for your spine and hips during floor-based core training.
Adjustable Ankle Weights — useful for advanced progression once your leg raise control is strong.
Ab Mat — helps support floor core work and can improve comfort during ab training.
Mini Resistance Bands — useful for warm-ups and hip stability work that supports better core control.
Foam Roller — helpful for warming up the hips, lower back, and trunk before core sessions.

Tip: Equipment is optional. For most people, a comfortable mat and excellent control are more valuable than adding resistance too early.
