Lower and Lift — Single Leg: A Complete Guide
Quick Intro
Lower and Lift — Single Leg is a mat Pilates exercise performed lying on the back with one leg bent and the foot flat on the mat while the other lowers slowly from 90 degrees and lifts back with control, before switching legs or repeating on the same side. Anchoring one leg on the floor while only the other does the work is what makes this the easier way into Lower and Lift.
Equipment Needed
No equipment is required. A Yoga Mat underneath is an optional way to cushion the spine and hips against a hard floor.
Why It Matters
Even a single working leg asks the deep core to sustain control across the full lower-and-lift range while the hip moves through its range, and matching the pace of the descent to the lift takes coordination. A deep core muscle that wraps around the torso like a corset (transverse abdominis) keeps the lower back from arching as the single leg lowers, and the abdominal muscles running down the front of the stomach (rectus abdominis) control the pace of the lower and the lift. The deep hip flexor (hip flexors, iliopsoas) drives the working leg through its range, and the lower back muscles (erector spinae) resist the pull the lowering leg places on the spine.
When to Do It
Lower and Lift — Single Leg fits well in the supine abdominal portion of a Pilates mat session, usually placed as the entry point before both legs move together. Building this one-leg pattern into two or three sessions a week is a reasonable starting pace.
Anyone with a current lower back issue should get individual guidance before adding this exercise, since a lowering leg pulls on the lower back even with the other leg bent for support.
Getting Ready
A few rounds of pressing the bent foot gently into the mat confirm a stable base before the working leg begins to move. A small partial lower, well short of the full range, previews the pacing the full set will need.
Step-by-Step Instructions
1. The setup. Lie on the back, one leg bent with the foot flat on the mat, the other extended to 90 degrees.
2. The lower. Slowly lower the extended leg toward the mat, keeping the lower back flat throughout.
3. The stop. Lower only as far as the back can stay still against the floor.
4. The lift. Lift the leg back to 90 degrees at the same controlled pace, then repeat for the set.
How Many, How Often
Lower and Lift — Single Leg is dosed by reps, with each lower-and-lift counting as one.
| Level | Where you’re at | What to do |
|---|---|---|
| Beginner | New to pacing the lower and the lift evenly | 2 sets of 6 to 8 reps per leg, with a smaller range |
| Intermediate | The pace stays even through a larger range | 2 to 3 sets of 8 to 10 reps per leg |
| Advanced | Comfortable with a full range and a steady pace | 3 sets of 10 to 12 reps per leg |
The lower and the lift moving at the same pace matters more here than how far the leg travels, since letting gravity speed up the lower trades deep core control for a faster-looking rep.
Modifications and Variations
The step up from this version moves both legs at once.
Compared to Lower and Lift, this version keeps one leg bent and anchored on the mat while only the other leg lowers and lifts, which halves the lever load compared to moving both legs together. Once one leg can complete a full range with an even pace and a still lower back, working toward both legs moving together in Lower and Lift is the natural next step.
Common Mistakes to Avoid
Lowering further than the lower back can hold. Chasing a lower leg position once the sacrum has already begun to lift off the mat turns a controlled core exercise into an uncontrolled lumbar arch. The floor of the lower should be set by the back’s position, not by how far the leg can physically reach.
Dropping the leg quickly just to reach the lift sooner. Letting the descent turn into a fast fall hands the work over to gravity instead of the deep core. Matching the tempo of the descent to the tempo of the lift keeps momentum out of the rep.
Letting the anchoring foot slide or lift during the rep. Allowing the bent leg’s foot to shift or come up off the mat removes the stable base the exercise depends on for protecting the lower back. Keeping that foot planted supports the working leg’s full range.
After Your Set
Drawing both knees up and holding them against the chest gives the lower back somewhere to recover after a set spent resisting a steady pull toward an arch. A gentle seated hamstring reach on the working leg, spine rounded rather than flat, finishes releasing the muscle that carried the single-leg range.
Going Deeper
This exercise usually works well as a way to build the even-pacing control the full two-leg version needs, without the doubled load of both legs testing that pacing before it exists. The descent tends to speed up unnoticed as the set goes on, letting gravity take over from the deep core. Keeping the lower and the lift on the same timing throughout the set, even if that means fewer total reps, builds control faster than letting the pace drift.
Someone new to this exercise generally manages a smaller range with an even pace within a few sessions, then works toward a fuller range over two to three weeks.
How to Know You’re Improving
- A lower back that stays flat through the whole range
- A lower and a lift that move at the same, even pace
- An anchoring foot that stays planted and still throughout
- A range that grows while the pacing stays even
A pace that never speeds up on the way down matters more than how far the leg travels.
Muscles Worked
- Transverse Abdominis (a deep core muscle that wraps around the torso like a corset, keeping the lower back from arching as the single leg lowers)
- Rectus Abdominis (the abdominal muscles running down the front of the stomach, controlling the pace of the lower and the lift)
- Iliopsoas (the deep hip flexor, driving the working leg through its range)
- Erector Spinae (the lower back muscles, resisting the pull the lowering leg places on the spine)
FAQ
Why move one leg while the other stays bent? Keeping one leg bent and anchored halves the lever load compared to moving both legs together, which makes the even-pacing control this exercise depends on easier to learn before the doubled load is added.
When is it time for the two-leg version? When each leg can lower and lift through a full range with an even pace and a flat lower back, start working toward Lower and Lift with both legs together.
Is some ab or hip flexor fatigue after this exercise normal? Yes, fatigue through the abdominals and hip flexors building up over several reps per leg is expected. A sharp, localized pain in the lower back is a different signal, worth stopping for and checking with a doctor or physical therapist if it lingers.
Is it normal for the pace to feel harder to control on one side? Yes, a control difference between the two legs is common, especially early on. Giving the less controlled side the same attention as the other tends to close that gap over time.
How often should the single-leg version be practiced? Fitting this into the supine abdominal portion of a mat session two to three times a week gives the one-leg pattern enough repetition to take hold.
