Side Kick Circles — Smaller Arc: A Complete Guide
Quick Intro
Side Kick Circles — Smaller Arc is a mat Pilates exercise performed lying on one side with the top leg lifted, sweeping it through a very small, tight circle just a few inches in diameter, keeping the pelvis far easier to hold still than the wider sweep of the full exercise allows. Shrinking the circle while still training every direction of the sweep is what makes this the easier way into Side Kick — Small Circles.
Equipment Needed
No equipment is required. A Yoga Mat underneath is an optional way to cushion the hip resting against the floor.
Why It Matters
Even a tight circle asks the hip to sustain repeated effort through a full set, and controlling that small circle without letting the pelvis rock takes coordinated stability. A smaller glute muscle at the side of the hip (gluteus medius) drives the leg through the tight circular path, and the deep hip flexor (hip flexors, iliopsoas) works through the forward arc of each small circle. The inner thigh muscles (adductors) control the leg through the inward arc, and a deep core muscle that wraps around the torso like a corset (transverse abdominis) keeps the pelvis from rocking as the leg circles.
When to Do It
Side Kick Circles — Smaller Arc works well in the side-lying leg-work portion of a Pilates mat session, usually placed as the entry point before the circle widens. Two to three sessions a week is a reasonable pace for building this tight, controlled sweep.
Anyone with a current hip or lower back issue should get individual guidance before adding this exercise, since even a small circling leg asks the pelvis to resist a rotating load.
Getting Ready
A few rounds of lifting the top leg to hip height and holding briefly confirm the starting position feels stable before any circling begins. A single very small circle, held slow, previews the control the full set will use.
Step-by-Step Instructions
1. The setup. Lie on one side, bottom leg slightly bent for support, top leg lifted to hip height.
2. The circle. Sweep the lifted leg through a small, tight circle, just a few inches across.
3. The check. Confirm the pelvis stays still through the whole small circle.
4. The switch. Complete the set of circles on one side, then switch to the other leg.
How Many, How Often
Side Kick Circles — Smaller Arc is dosed by reps, with each small circle counting as one.
| Level | Where you’re at | What to do |
|---|---|---|
| Beginner | New to keeping the pelvis still through any circle | 2 sets of 6 to 8 circles per side, kept very tight |
| Intermediate | The pelvis stays still through a slightly larger small circle | 2 to 3 sets of 8 to 10 circles per side |
| Advanced | Comfortable expanding the circle while control holds | 3 sets of 10 to 12 circles per side |
A motionless pelvis matters more here than how far the leg travels, since a wider circle only counts as progress once stillness through the current size is automatic.
Modifications and Variations
The step up from this version is a wider circle.
Compared to Side Kick — Small Circles, this version keeps the sweep only a few inches wide, which makes the pelvis considerably easier to keep still while the same circular hip pattern is trained. Once the pelvis can stay still through a full set of tight circles, widening the sweep gradually toward the fuller circle is the natural next step.
Common Mistakes to Avoid
Letting the circle grow bigger before the pelvis is ready. Sweeping the leg through a wider arc just to make the movement look more like the full exercise skips the stability this smaller version is meant to build first. A deliberately tight circle is the point of this version.
Allowing the pelvis to rock even slightly during the sweep. A small circle that still lets the hips tip loses the one advantage this version offers over a wider sweep. The hips should feel anchored throughout the small arc.
Rushing through the circles. Speeding through the small circle to finish the set skips the sustained control a slower pace provides. A tiny, controlled circle with a motionless pelvis is worth more than a rushed one.
After Your Set
Rolling onto the back and hugging one knee across the body, foot resting near the opposite hip, releases the outer hip after a set of tight, repeated circles. A gentle standing hip flexor stretch on the working side finishes easing out any remaining tightness at the front of the hip.
Going Deeper
This exercise usually works well as a way to build the pelvis-stability skill the full-range version needs, without the extra leverage of a wider sweep testing that stability before it exists. Once a certain circle size stops feeling challenging, it’s tempting to keep training at that same comfortable size. Expanding the arc in small increments, checking each time that the pelvis stays still, keeps this version moving toward the full range.
Someone picking this up for the first time typically manages a tight, well-controlled circle within a handful of sessions, then works toward a noticeably wider small circle across the following two or three weeks.
How to Know You’re Improving
- A pelvis that stays anchored through the whole circle
- A circling leg that stays at a consistent hip height
- An arc that widens gradually while the pelvis stays still
- A sweep that feels driven by the hip, not swung by momentum
A pelvis that stays level is a better measure than the width of the circle.
Muscles Worked
- Gluteus Medius (a smaller glute muscle at the side of the hip, driving the leg through the tight circular path)
- Iliopsoas (the deep hip flexor, working through the forward arc of each small circle)
- Adductors (the inner thigh muscles, controlling the leg through the inward arc)
- Transverse Abdominis (a deep core muscle that wraps around the torso like a corset, keeping the pelvis from rocking as the leg circles)
FAQ
What’s the benefit of starting with such a small circle? A tight circle makes it considerably easier to keep the pelvis still, so the hip-stability skill this exercise depends on can be learned before a wider, more demanding sweep is added on top of it.
When is it time to widen the arc? When the pelvis stays still at the current circle size, with no rocking or tipping anywhere in the sweep, expand it a little and work gradually toward Side Kick — Small Circles.
Is a tired outer hip after the small circles normal? Yes, fatigue through the outer hip after several small circles per side is expected. A sharp, isolated pain anywhere in the hip is a different signal: stopping the set and getting a doctor or physical therapist’s opinion is the better response if it doesn’t settle.
Is it normal for one hip to feel more controlled than the other? Yes, a strength or control difference between the two sides is common. Matching the circle count on the less controlled side to the other side is a reasonable way to close that gap over time.
How often should the smaller arc be practiced? Two to three times a week, as part of the side-lying leg-work portion of a broader mat session, is enough repetition to build this tight, controlled sweep.
