Leg Lowers: A Complete Guide
Quick Intro
Leg Lowers is a mat Pilates exercise performed lying on the back with both legs extended straight up at 90 degrees, slowly lowering them toward the floor only as far as the lower back can stay flat against the mat, then lifting back to 90 degrees. The spine never moves; only the legs do, which makes the imprint (the lower back pressed flat into the mat) the test of the exercise.
Equipment Needed
No equipment is required. A Yoga Mat underneath is an optional comfort choice for cushioning the spine against a hard floor.
Why It Matters
Sustaining the imprinted position through a slow lower-and-lift asks for staying power in the abdominals, and the hamstrings need enough length to let the legs travel without pulling the pelvis along. A deep core muscle that wraps around the torso like a corset (transverse abdominis) is what keeps the lower back pinned to the mat as the legs descend, 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 legs through the movement, and the lower back muscles (erector spinae) work to resist the arch the legs are constantly threatening to pull into the spine.
When to Do It
Leg Lowers works well in the supine abdominal portion of a Pilates mat session, usually placed among the other leg-lowering and leg-circling exercises once the core already feels warmed up. Two to three sessions a week suits most people building this control.
Anyone with a current lower back issue should get individual guidance before adding this exercise, since even a small loss of the imprinted position sends load into an unsupported lumbar spine.
Getting Ready
Lying with both legs at 90 degrees for a few breaths, pressing the lower back gently into the mat, previews the imprint the whole exercise depends on. A few slow single-leg lowers confirm that same imprint can be held while a limb moves.
Step-by-Step Instructions
1. The setup. Lie flat on the back, both legs extended straight up at 90 degrees, lower back pressed into the mat.
2. The lower. Inhale and lower both legs together toward the floor, stopping the instant the lower back starts to lift off the mat.
3. The pause. Hold briefly at that lowest controlled point, keeping the imprint intact.
4. The lift. Exhale and lift both legs back to 90 degrees with the same control used to lower them.
How Many, How Often
Leg Lowers is dosed by reps, with each lower-and-lift counting as one.
| Level | Where you’re at | What to do |
|---|---|---|
| Beginner | New to keeping the back flat through the lower | 2 sets of 4 to 5 reps, stopping well above the floor |
| Intermediate | The imprint holds through a moderate range | 2 to 3 sets of 6 to 8 reps |
| Advanced | Comfortable with a full range and a steady imprint | 3 sets of 8 to 10 reps, lowering closer to the floor |
The lower back staying flat against the mat matters more here than how close the legs get to the floor, since chasing a lower position at the cost of an arching spine trades core control for a bigger-looking range.
Modifications and Variations
As an easier version, Leg Lowers — One Leg at a Time lowers only one leg while the other stays bent or anchored, cutting the load on the lower back roughly in half.
As a harder version, Leg Lowers — Below 45 Degrees continues the lower past the point most people’s imprint starts to break, asking the deep core to hold the pelvis still through a longer lever.
Common Mistakes to Avoid
Lowering past the point the back can stay flat. Chasing a lower leg position once the lower back has already started 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, not by how far the legs can physically reach.
Rushing the lower and lift. Letting gravity pull the legs down quickly, or snapping them back up, skips the sustained tension this exercise is built around. A slow, even pace through both directions keeps the deep core doing the work.
Letting the ribs flare as the legs descend. Allowing the ribcage to lift and the belly to push outward removes the corset-like bracing that protects the lower back through the movement. Keeping the ribs drawn down and in holds the imprint steady as the legs travel.
After Your Set
Hugging both knees into the chest and rocking gently from side to side releases the lower back after a set built around resisting a constant arching pull. A standing or seated hamstring stretch on each leg eases out the muscles that controlled the legs through their full range.
Going Deeper
This exercise usually works well as a direct test of how well the lower back can stay anchored while a heavy limb lever moves through space, since the legs act as a long pendulum trying to pull the spine into an arch with every inch they travel. The legs can reach lower than the core can control, so it’s tempting to chase range at the expense of the imprint. Keeping the range a little smaller and the imprint solid builds strength faster than reaching for the floor too soon.
Someone new to this exercise generally holds the imprint through a moderate range within a couple of sessions, then works toward a fuller range with the back still flat over three to four weeks.
How to Know You’re Improving
- A lower back that stays pressed into the mat through the whole range used
- A lower and lift that both move at the same controlled, even pace
- Ribs that stay drawn in as the legs descend
- A working range that lowers gradually while the imprint stays intact
A lower back that never leaves the mat matters more than how close the legs get to the floor.
Muscles Worked
- Transverse Abdominis (a deep core muscle that wraps around the torso like a corset, keeping the lower back pinned to the mat)
- 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 legs through the movement)
- Erector Spinae (the lower back muscles, resisting the arch the legs constantly threaten to pull into the spine)
FAQ
How far should the legs lower? Only as far as the lower back can stay flat against the mat. The moment the back starts to lift or arch is the floor for that set, whether that’s a small range or nearly to the floor.
Why does this exercise emphasize the imprint so much? The imprint is what keeps the load in the deep abdominals instead of letting it spill into an unsupported lower back. Losing it turns a core exercise into unnecessary strain on the spine.
Is some deep ab fatigue after this exercise normal? Yes, fatigue through the deep abdominals after several controlled reps is expected. Sharp pain anywhere in the lower back is a separate issue, one worth easing off for and raising with a doctor or physical therapist if it continues.
Is bending the knees acceptable when the back won’t stay flat with straight legs? A slight bend in the knees is a reasonable way to reduce the lever length while the imprint is still developing, though Leg Lowers — One Leg at a Time is the easier version to use if the movement still feels out of reach.
How often should Leg Lowers be practiced? Two to three times a week, as part of the supine abdominal portion of a broader mat session, is enough repetition to build control.
