Swan Prep — Elbows Bent: A Complete Guide
Quick Intro
Swan Prep — Elbows Bent is a mat Pilates exercise that performs the same Swan Prep chest lift while keeping the elbows bent and close to the ribs throughout, instead of pressing toward straighter arms. Keeping that bend the whole time shortens how far the chest needs to rise and takes load off the back extensors, making this the gentlest way into Swan.
Equipment Needed
No equipment is required, though a Yoga Mat placed underneath is a reasonable comfort choice if the hips and pelvis rest against a hard floor.
Why It Matters
Keeping the elbows bent shortens the range and takes demand away from the back extensors that would otherwise be sustaining a fuller lift. The lower back muscles (erector spinae) still drive the small lift available at this range, and the main chest muscle (pectoralis major) supports the upper body through the bent-elbow position. The back of the upper arm (triceps brachii) holds the elbows at their fixed bend rather than letting them drift toward straight, and the largest glute muscle (gluteus maximus) keeps the pelvis anchored to the mat.
When to Do It
Swan Prep — Elbows Bent works well at the very start of the prone portion of a Pilates mat session, especially for anyone whose back extensors aren’t yet ready for the fuller Swan Prep hold. Two or three sessions a week suits most people building toward the straighter-arm version.
Anyone with a current lower back issue should get individual guidance before adding this exercise, since even this smaller range asks the lumbar spine for an extension hold.
Getting Ready
Lying prone and gently arching the upper back a few times, without lifting into the position yet, warms up the same extension range this smaller lift will use. Bending the elbows and resting the forearms lightly near the shoulders for a moment previews the fixed arm position the lift will hold.
Step-by-Step Instructions
1. The setup. Lie face down, elbows bent and close to the ribs, hands resting near the shoulders, legs hip-width apart and parallel.
2. The lift. Exhale and press lightly into the hands to lift the chest a small amount, keeping the elbow bend fixed the entire time.
3. The hold. Inhale and hold the lifted position, with the motion focused in the upper back.
4. The lower. Exhale and reverse the motion, returning the chest to the mat at the same unhurried pace it left.
How Many, How Often
Swan Prep — Elbows Bent is dosed by reps, with each lift, hold and lower counting as one.
| Level | Where you’re at | What to do |
|---|---|---|
| Beginner | New to the bent-elbow hold | 2 sets of 3 to 4 reps, keeping the lift very small |
| Intermediate | The small lift feels controlled and back-driven | 2 to 3 sets of 5 to 6 reps |
| Advanced | Ready to test a straighter-arm hold | 3 sets of 6 to 8 reps, then trying the full Swan Prep occasionally to check readiness |
Keeping the elbows at a fixed bend throughout matters more here than how high the chest rises, since letting them straighten partway through the lift borrows range this version is meant to postpone.
Modifications and Variations
As a harder version, Swan Prep straightens the arms further through the same lift, asking the back extensors to sustain a taller position without the bent-elbow support this version provides.
No easier version of the lift sits below this one.
Common Mistakes to Avoid
Letting the elbows straighten as the lift continues. Allowing the arms to drift toward straight partway through the hold turns this into the fuller Swan Prep before the back extensors are ready for it. Keeping the bend fixed from the first breath to the last is the point of this variation.
Pressing hard through the hands to compensate for the smaller range. Pushing forcefully into the hands to make up for the reduced lift height shifts the work away from the back extensors this exercise is meant to train. A light press is all the bent-elbow position calls for.
Skipping straight to the full Swan Prep before this version feels easy. Moving on to the straighter-arm hold while this smaller lift still feels effortful skips the gradual loading this entry point is designed to provide. Staying here until the small lift feels easy protects the lower back later on.
After Your Set
Folding back so the hips settle toward the heels with the arms resting alongside the body gives the lower back a gentle release after this small extension hold. A few slow breaths in that folded position are usually enough to ease out the little tension this version leaves behind.
Going Deeper
This exercise usually works well as a way into back extension work, since the bent elbows let the back extensors get used to holding a lift before they’re asked to sustain a fuller range. The smaller lift can start to feel too easy, and the arms tend to straighten without meaning to, which loses the gradual loading this version provides. Staying at this bent-elbow range until the hold feels comfortable tends to prepare the back extensors better than rushing ahead.
Someone new to back extension work generally finds this small hold comfortable within the first couple of sessions, then feels ready to test the fuller Swan Prep hold within two to three weeks.
How to Know You’re Improving
- A bent-elbow position that holds fixed for the entire set
- A press that feels light through the hands while the back does the work
- Less effort needed to sustain the hold across a full set
- Readiness to test the straighter-arm Swan Prep hold
A small, back-driven lift held with the elbows fixed is the sign of readiness for the fuller Swan Prep hold.
Muscles Worked
- Erector Spinae (the lower back muscles, driving the small lift available at this range)
- Pectoralis Major (the main chest muscle, supporting the upper body through the bent-elbow position)
- Triceps Brachii (the back of the upper arm, holding the elbows at their fixed bend)
- Gluteus Maximus (the largest glute muscle, keeping the pelvis anchored to the mat)
FAQ
Is Swan Prep — Elbows Bent easier than the standard Swan Prep hold? Yes. Keeping the elbows bent shortens how far the chest can rise and takes load off the back extensors, which is what makes this a gentler entry point into the same lift.
When is it time for the straighter-arm Swan Prep? Once the bent-elbow hold feels comfortable and clearly back-driven across a full set, straightening the arms further through Swan Prep is a reasonable next step.
Is some lower back fatigue after this exercise normal? A mild fatigue through the lower back after several small holds is expected, even at this reduced range. Sharp pain anywhere in the spine is a different matter, one worth checking with a doctor or physical therapist if it doesn’t ease off.
How does the standard Swan Prep differ? Swan Prep presses toward straighter arms and lifts the chest higher off the mat, while this version keeps the elbows bent and the lift smaller throughout.
How often should the bent-elbow lift be practiced? Two or three sessions a week is enough to build the back extensors’ readiness for the fuller Swan Prep hold.
