How to do it
How do you do the Roll-Up?
- Lie on your back with your legs long and together, feet flexed, arms overhead.
- Breathe in and float your arms up to the ceiling.
- Breathe out, bring your chin to your chest and roll up one vertebra at a time, reaching your arms forward.
- Stretch forward over your legs in a C-curve, belly scooped.
- Breathe in, then breathe out and roll back down one vertebra at a time; do 5–6 slowly.
Cues
- Peel your spine off the mat like a wheel.
- Heels stay heavy, legs reach long.
- Scoop your belly as you curl.
Common mistakes
- Using momentum: slow down, bend your knees or hold your thighs if you can't roll up yet.
- Lifting your legs: press your heels into the mat.
- Collapsing at the top: lift your belly in and up over your legs.
Form in detail
What does good form look like?
The version in our demo
The classical mat Roll-Up (Joseph Pilates, Return to Life, exercise 2; Balanced Body mat manual): legs long and together, feet flexed, a slow articulation of the spine up and over the legs and back down, not a sit-up.
Starting position
Lying long on the mat, legs straight and together, feet flexed (toes to the ceiling), arms overhead just above the mat.
The movement
1. Breathe in: float the arms up to the ceiling. 2. Breathe out: chin to chest, curl the head and shoulders up, then peel the spine off the mat one part at a time, reaching the arms forward; roll up over the sit bones and stretch forward over the legs in a C-curve, belly scooped, reaching past the toes. 3. Breathe in: lengthen at the reach. 4. Breathe out: tip the pelvis back and roll down one part at a time, arms reaching forward, until the head lands; the arms float back overhead.
Breathing
In to prepare, out to roll up, in at the top, out to roll down.
Tempo
7 s: in 1 s (arms up), out 2.6 s (roll up and forward), in 0.6 s (lengthen), out 1.8 s (roll down), and the arms float back overhead over 1.5 s as the back lands (5.5–7 s). The roll is paced by the head's path, so the head travels at an even speed and never drops; the arms follow the clock. Real practice: 5–6 slow repetitions.
Form in numbers
What are the angles and distances?
- Legs straight (knees 4–6°), together; heels stay on the mat throughout (no lift).
- Lying: arms overhead 4–5 cm above the mat; arms straight (elbows about 10°).
- Curl first: the spine rounds about 62° while the pelvis is still on the mat, then the pelvis rolls up.
- Arms: vertical at the top of the in-breath, 25° above the legs by mid-roll, reaching past the toes at the end.
- Reach: pelvis tipped forward 106° from lying (hip flexion about 106°), spine rounded 50°; wrists 5 cm past the ankles, head 28 cm above the knees.
