Side Kick — Inner Thigh Lift: A Complete Guide
Quick Intro
Side Kick — Inner Thigh Lift is a mat Pilates exercise performed lying on the side with the top leg resting on the mat in front of the body and the foot flat, lifting the bottom leg straight toward the ceiling with the inner thigh facing up, then lowering it slowly with control. The bottom leg does the work here, resisting gravity on both the way up and the way down.
Equipment Needed
No equipment is required. A Yoga Mat underneath is an optional way to pad the hip and shoulder resting on the floor.
Why It Matters
Lifting and lowering the bottom leg repeatedly against gravity takes staying power in the inner thigh, and reaching the leg toward the ceiling asks for hip range. The inner thigh muscles (adductors) do the primary lifting and lowering work throughout. A deep core muscle that wraps around the torso like a corset (transverse abdominis) keeps the torso stable as the leg moves, and the waist muscles along the side of the torso (obliques) help hold the body in one straight line through every rep.
When to Do It
Side Kick — Inner Thigh Lift works well in the side-lying portion of a Pilates mat session, usually grouped with the other side-lying leg work. Two to three sessions a week is a reasonable pace for building this inner-thigh control.
Anyone managing a current hip or groin issue should get individual guidance before adding repeated resisted leg lifts.
Getting Ready
Lying on the side with the top leg resting comfortably in front for a few breaths previews the support position the lift works from. A few small, slow lifts of the bottom leg confirm the inner thigh can move the leg without the hips rolling.
Step-by-Step Instructions
1. The setup. Lie on the side, top leg bent and resting on the mat in front, foot flat.
2. The lift. Lift the bottom leg straight toward the ceiling, keeping the inner thigh facing upward.
3. The pause. Hold briefly at the top of the lift, actively squeezing the inner thigh.
4. The lower. Lower the leg slowly with control, resisting gravity the whole way.
How Many, How Often
Side Kick — Inner Thigh Lift is dosed by reps, with each lift-and-lower counting as one.
| Level | Where you’re at | What to do |
|---|---|---|
| Beginner | New to lifting the bottom leg without rolling the hips | 2 sets of 6 to 8 reps per side, with a smaller lift |
| Intermediate | The lift feels controlled through a fuller range | 2 to 3 sets of 8 to 10 reps per side |
| Advanced | Comfortable with a full lift and a slow controlled lower | 3 sets of 10 to 12 reps per side |
Actively squeezing the inner thigh on the lift matters more here than how high the leg travels, since letting momentum carry the leg trades muscular work for a bigger-looking range.
Modifications and Variations
As an easier version, Inner Thigh Lift — Reduced Height shortens the lift so the leg travels through a smaller range, reducing the demand while the inner-thigh pattern is still being learned.
As a harder version, Inner Thigh Lift — Pulsed Hold adds small pulses at the top of the lift, asking the inner thigh to work under sustained tension.
Common Mistakes to Avoid
Letting momentum carry the leg through the lift. Swinging the bottom leg upward with speed, with the inner thigh playing only a small part, only gives the appearance of a full range. A slower, deliberate lift keeps the adductors doing the work they’re meant to.
Dropping the leg quickly on the way down. Letting gravity pull the leg back to the mat skips the resisted, controlled lower this exercise is built around. Lowering with the same intentional control used to lift is what makes the descent count as much as the lift.
Letting the hips roll backward as the leg lifts. Allowing the pelvis to tip away from the lifting leg borrows range from the hips that should be coming from the inner thigh alone. Keeping the hips stacked and still keeps the work in the inner thigh.
After Your Set
Lying on the back and gently opening both knees out to the sides in a supported butterfly position stretches the inner thighs after a set of repeated lifts. A standing or seated adductor stretch on the working leg eases out any tightness that built up through the sustained effort.
Going Deeper
This exercise usually works well as a direct, isolated test of inner-thigh strength, since lifting a straight leg against gravity from a side-lying position gives the adductors very little help from anywhere else in the body. Swinging the leg with momentum can reach a similar height to a controlled lift with far less work from the inner thigh. Keeping the lift slower and more deliberate, even if the range looks smaller, builds strength faster.
Someone new to this exercise generally manages a controlled lift through a moderate range within a few sessions, then works toward a fuller range with the same control over two to three weeks.
How to Know You’re Improving
- A lift that comes from a deliberate inner-thigh squeeze, not a swing
- A lower that stays as slow and controlled as the lift
- Hips that stay stacked and still
- A lift height that grows while the controlled pace stays consistent
A lift driven by a deliberate squeeze matters more than how high the leg travels.
Muscles Worked
- Adductors (the inner thigh muscles, doing the primary lifting and lowering work throughout)
- Transverse Abdominis (a deep core muscle that wraps around the torso like a corset, keeping the torso stable as the leg moves)
- Obliques (the waist muscles along the side of the torso, holding the body in one straight line through every rep)
FAQ
Why does this exercise target the inner thigh? Lifting a straight leg from a side-lying position against gravity puts the inner thigh in the position where it has to do nearly all the lifting work, with very little assistance from the other hip muscles. That is what isolates the inner thigh.
Is it normal for one leg to feel weaker than the other? Yes, a difference in inner-thigh strength between the two legs is common. Training both sides with equal attention tends to close that gap gradually over time.
Is some inner thigh fatigue after this exercise normal? Yes, fatigue through the inner thigh after several reps per side is expected. Sharp pain anywhere in the groin or hip is a different matter, one worth easing off for and raising with a doctor or physical therapist if it continues.
Is a smaller lift acceptable if the full height feels like too much? Yes, a smaller range is a reasonable way to build the pattern before reaching for a full lift, and Inner Thigh Lift — Reduced Height is built that way.
How often should the inner thigh lift be practiced? Two to three times a week, as part of the side-lying portion of a broader mat session, suits most people building this inner-thigh control.
