Want legs that look leaner, stronger and more toned from every angle? These six best inner thigh workout target your adductors (aka inner thighs), but also work your glutes, core, and stabilizers to sculpt your entire leg. Suitable for beginner and advanced individuals alike.
Often overlooked, the muscles in your inner thighs (the adductor longus, brevis, magnus, pectineus and gracilis) play a vital role in providing stability to your legs, strengthening your hips and achieving balanced lower body strength. They also help to prevent injury to your knees and hips and give you those coveted lean inner thighs.
6 Best Inner Thigh Workout to Burn Thigh Fat
1. Sumo Squats
The inner thigh muscles (adductors) are the primary muscles involved, along with the gluteal muscles (glutes), quadriceps, hamstrings and the core.
How to do it:
- Stand tall: feet wider than shoulder-width (sumo stance — about 1.5–2x shoulder width), toes turned out 30–45° (like a sumo wrestler stance), core braced (navel to spine), chest up, gaze forward.
- Engage core, keep back neutral, shoulders relaxed.
- Inhale: Push hips back first (like sitting into a chair), bend knees, lower until thighs are parallel to floor (or as deep as mobility allows safely).
- Keep weight in heels/midfoot, knees tracking over toes (push knees out hard — feel deep stretch/tension in inner thighs), chest proud, back straight.
- Exhale: Drive through heels, squeeze glutes hard to stand tall (full hip/knee extension at top).
- Optional: Add small pulse at bottom (up/down 1–2 inches) or hold bottom position 2–3 seconds for extra burn.
-
Reps/Sets: 15–25 reps × 3–4 sets.
Why It Works: The extra-wide stance with toes turned out puts maximum tension on the inner thighs (adductors), while also engaging the glutes and quadriceps. This exercise builds lean muscle, boosts metabolism, firms the inner legs, lifts the buttocks, and creates a sculpted, toned look from the thighs to the hips.
2. Standing Side Leg Raises
The muscles that are targeted are the adductors (inner thighs – stabilization), the abductors (outer thighs/hips – glute medius/minimus), the core, and the balance.
How to do it:
- Stand tall: feet together or hip-width apart, core braced, chest up, hands on hips or lightly holding a chair/wall for balance (avoid leaning heavily).
- Shift weight fully onto right leg (slight soft bend in knee), engage core/glutes.
- Exhale: Lift left leg straight out to the side 12–24 inches (lead with heel, toes pointing forward — no swinging or rotating hips).
- Hold 1–2 seconds at top (squeeze outer hip/glute), keep hips level and square to front.
- Inhale: Lower slowly with control (resist gravity — 3–4 seconds down, don’t drop).
- Complete all reps on one side, then switch legs.
-
Reps/Sets: 15–25 reps per leg × 3 sets.
Why It Works: The standing position forces the inner thighs to stabilize the body while lifting the working leg. This builds strength and endurance in the adductors, tones the inner and outer legs, improves hip mobility and stability, and enhances overall leg definition and balance.
3. Side Lunges 
The muscles worked are the adductors (inner thighs), glutes, quads, hamstrings, core, balance and flexibility.
How to do it:
- Stand tall: feet together or hip-width apart, core braced, chest up, hands on hips or in front for balance.
- Exhale: Step wide to right (2–3 feet), shift weight onto right foot, bend right knee, push hips back.
- Lower until right thigh is parallel (or close), left leg straight, left foot flat on floor (toes forward).
- Keep torso upright, right knee tracking over right toes (no caving in), chest proud.
- Inhale: Push off right heel, squeeze glutes, return to center standing tall.
- Immediately step left — alternate sides smoothly.
-
Reps/Sets: 10–15 reps per side (20–30 total) × 3 sets.
Why It Works: Side lunges stretch and strengthen the inner thighs through deep adduction. They tone the inner leg, improve hip flexibility and mobility, enhance balance and coordination, and sculpt a leaner, stronger lower body from every angle.
4. Plank with Leg Lifts
The inner thigh muscles (adductors) are stabilised and abducted. The transverse abdominis, obliques, glutes (medius/minimus), shoulders and full core are also worked.
How to do it:
- Start in forearm plank: elbows directly under shoulders, forearms on floor, body in a straight line from head to heels, core engaged (navel to spine), glutes and quads squeezed tight — no sagging hips or piking butt up.
- Keep neck neutral (gaze slightly forward of hands), shoulders away from ears.
- Breathe steadily — don’t hold breath.
- Exhale: Slowly lift right leg 6–12 inches off floor (straight back or slightly out to side), squeeze inner thigh and glute — keep hips level and square to floor (no rotation or dipping).
- Hold 1–2 seconds at top (feel inner thigh and glute working hard).
- Inhale: Lower slowly with control (resist gravity — 3–4 seconds down, don’t drop).
- Alternate legs — continue for reps or time.
-
Reps/Sets: 12–20 lifts per leg × 3 sets (or hold each lift 2–3 sec for isometric focus).
Why It Works: The forearm plank builds deep core stability, while leg lifts force the inner thighs to work isometrically and dynamically. This tightens the midsection, strengthens the inner legs, improves posture, enhances hip stability, and creates a leaner, more defined leg line from every angle.
5. Fire Hydrants
The muscles involved are the gluteus medius/minimus (outer/upper glutes), adductors (inner thighs – stabilization) and the core.
How to do it:
- Start on all fours (quadruped): hands directly under shoulders, knees under hips, core braced, back neutral (no arching or rounding).
- Keep right knee bent 90°, foot flexed (toes pointing toward ceiling).
- Exhale: Lift right knee out to the side (like a dog at a fire hydrant) — lead with knee, keep hips level and square to floor.
- Raise as high as possible without rotating hips/back (squeeze glute hard at top — feel it in side of butt).
- Inhale: Lower slowly with control (3–4 sec descent — don’t let knee touch floor).
- Complete all reps on one side, then switch legs.
-
Reps/Sets: 15–25 reps per leg × 3 sets.
Why It Works: The side leg lift from a quadruped position strengthens the outer glutes while the inner thighs stabilize. This exercise tones the hips, reduces the appearance of saddlebags, improves hip mobility and stability, and creates balanced, sculpted legs with stronger inner-thigh definition.
6. Lying Side Leg Raises
The muscles that are targeted are the adductors (inner thighs – stabilisation and abduction), the gluteus medius/minimus and the core.
How to do it:
- Lie on right side: head resting on right arm (or pillow for neck support), legs stacked straight, core engaged (navel to spine).
- Stack hips/shoulders perfectly vertical — no rolling forward or backward (place top/left hand on floor in front or on hip for balance).
- Exhale: Slowly lift left leg upward 6–12 inches (lead with heel, toes pointing forward — avoid pointing toes up to ceiling).
- Hold 1–2 seconds at top (squeeze inner thigh/hip hard — feel burn in inner leg).
- Inhale: Lower slowly with control (resist gravity — 3–4 seconds down, don’t drop or swing).
- Complete all reps on one side, then switch (lie on left side, lift right leg).
-
Reps/Sets: 15–25 reps per side × 3 sets.
Why It Works: The lying position isolates the inner thighs through an isometric hold and controlled lift. This exercise builds strength and endurance in the adductors, tones the inner legs, enhances hip stability, and creates leaner, more defined thighs with minimal joint stress.
These inner thigh workout form the foundation of an effective leg-sculpting routine, helping you to achieve the toned, defined muscles you’ve always wanted. Perform them consistently and with perfect form to tone your thighs and legs.
