Pilates Reformer Lying Calf Raise
What Is the Pilates Reformer Lying Calf Raise?
Pilates Reformer Lying Calf Raise is an isolation exercise that primarily targets the lower legs. It is a beginner-level movement performed lying face up on the reformer carriage with the legs long and the balls of both feet on the footbar. The knees stay straight and the ankles do all the work: the heels lower below the bar and then press back up, moving the carriage a short distance against the spring resistance. The load comes from the carriage springs rather than from any added weight, so it can be set as light as needed.
It usually appears at the end of the reformer footwork series, once the legs are already warm from the knee-extension positions, and it is often the last thing done before standing or single-leg work. Because the spine is supported and the body is not being lifted, it is one of the few ways to train the calves through a full ankle range without loading the spine or balancing on one foot. That makes it useful as ankle preparation, as calf work for clients who cannot tolerate standing loads, and as a way to find out how much ankle range someone actually has before asking for it elsewhere in the session.
The straight knee is what decides the muscle emphasis. The gastrocnemius crosses the knee as well as the ankle, so keeping the legs long holds it in a position where it can contribute, and both it and the soleus work through the press. Bending the knee, as a seated calf raise does, shortens the gastrocnemius and leaves most of the work to the soleus. This is also what separates the exercise from the rest of the footwork series: in Pilates Reformer Lying Knee Extension and its toes and heels variations the ankle angle is held still while the knees open and close, and here the opposite is true. Pilates Reformer Lying Running works the same heel-down, heel-up action one side at a time, lowering one heel as the other lifts.
It suits beginners, runners, dancers and anyone rebuilding ankle strength after time in a boot or off their feet. If the heel drop feels sharp or the calves cramp early, cut the range and the spring load rather than the reps, and build the range back over a few sessions. The part worth paying attention to is where the pressure sits under the foot: keeping it under the ball of the big and second toes through both directions is what keeps the ankle tracking straight, and most of the sloppy reps in this exercise start with the foot rolling instead of the ankle moving.

Instructions
- Set the reformer springs to a moderate load and set the footbar at a height that lets your legs straighten comfortably against it.
- Lie face up on the carriage with your head on the headrest and your shoulders settled against the shoulder rests.
- Place the balls of both feet on the footbar, feet parallel and about hip width apart, with your toes resting over the top of the bar.
- Rest your arms along your sides with the palms down, and set your pelvis neutral with a small natural gap under your lower back.
- Press the carriage away until your legs are long and your knees are straight but not locked.
- Lower your heels below the footbar until you feel a stretch through the calves, letting the carriage travel back in toward the bar.
- Keep your knees straight as the heels lower so the movement stays at the ankle.
- Press the balls of your feet into the bar to extend your ankles, lifting your heels back in line with your shins and pushing the carriage away again.
- Keep the pressure under the ball of the big and second toes at the top so your feet do not roll to their outer edges.
- Repeat for 8 to 10 reps at the same slow count in both directions, keeping your head, shoulders and pelvis still throughout.
Common Mistakes
Bending the knees to move the carriage
Letting the knees bend and straighten turns the exercise back into a footwork press driven by the quads, when the point here is that the ankle moves the carriage on its own.
Dropping the heels instead of lowering them
Releasing the ankle and letting the springs pull the heels down removes the controlled lowering half of every rep and bounces the calf and Achilles at the end of the range.
Barely lowering the heels
Stopping with the heels level with the footbar skips the lower half of the ankle's range, which is the part that makes the exercise worth doing.
Rolling onto the outer edge of the foot
As the heels lift, the pressure slides toward the little toe side unless it is held under the ball of the big and second toes, which sends the ankle out of line under the whole load.
Rocking the pelvis with each rep
Arching and flattening the lower back in time with the heels means the trunk is helping push the carriage, and it usually means the spring setting is too heavy.
Clawing the toes into the bar
Gripping the bar with the toes rather than letting them rest over it concentrates the load under them and is the most common cause of foot and arch cramps in this position.
Injuries
Pilates Reformer Lying Calf Raise is a low risk exercise when performed with proper technique. The spine is supported on the carriage, both feet stay on the footbar, the carriage travel is only as long as the ankle's range, and the springs can be set as light as the client needs. The strain points that do exist are concentrated below the knee: the Achilles tendon and the calf at the bottom of the heel drop, the ball of the foot and the toes, which carry the whole press through a small contact area, and the back of the knee if the legs are jammed hard into a locked position to keep them straight.
Lower the heels rather than dropping them, and take a slow count in each direction so the carriage never bounces at the end of the range. Go to the end of the ankle range you can control instead of forcing extra depth, and keep the pressure spread across the ball of the foot, under the big and second toes, so the foot does not roll in or out as the heels lift. Keep the knees straight without locking them, and keep the pelvis and lower back still: if the back arches and flattens with each rep, the trunk is helping move the carriage and the load is too heavy.
To make it easier, drop a spring and shorten the heel drop at first, then build the depth back over a few sessions until you are using the whole ankle range. To progress, add a spring, slow the tempo further, pause at the bottom of the heel drop, or work one leg at a time. Away from the reformer, Leg Press Calf Raise trains the same straight-knee ankle press with weight-stack loading, and Bodyweight Calf Raise does it standing.
Stop the set for sharp pain in the Achilles tendon or the back of the heel, for pain under the forefoot that builds rep after rep, or for a calf cramp that does not release when you come off the bar and stretch the foot out. Anyone with an irritable Achilles tendon, a current plantar fascia problem, recent ankle or knee surgery, or pain at the end of their dorsiflexion range should agree the range and spring setting with a clinician or instructor before working through the full heel drop.

Frequently Asked Questions
- Q: How is this different from reformer footwork?
In footwork the ankle angle is held still and the knees open and close to move the carriage, as in Pilates Reformer Lying Knee Extension and its on toes variation. Here it is the other way round: the knees stay straight for the whole set and the ankle is the only joint that moves.
- Q: Is this the same as Pilates Reformer Lying Running?
No. Pilates Reformer Lying Running works the heels one side at a time, lowering one as the other lifts, so one calf is lengthening while the other presses. Here both heels move together, so the calves load and unload at the same time and the carriage travels as one smooth press.
- Q: Will this build bigger calves?
It is better at building ankle control, range and endurance than size, because the springs are light compared with what the calves carry under body weight and the body is not being lifted. If size is the goal, keep this as ankle preparation and do the heavy work standing, with something like Machine Standing Calf Raise.
- Q: How many springs should I use?
Spring settings differ between reformer brands, so judge it by how the carriage behaves rather than by a number. The load is right when you can feel resistance at the top of the press and still lower the heels slowly, without the carriage bouncing at the bottom or the pelvis rocking to help.
- Q: Why do the knees stay straight?
The gastrocnemius crosses the knee as well as the ankle, so a straight leg keeps it in a position where it can work through the press. Bending the knee shortens it and leaves most of the job to the soleus underneath, which is what a bent-knee movement like Machine Seated Calf Raise is for.
