A Pilates reformer that is not set up for your body will feel uncomfortable, limit your range of movement, and reduce the effectiveness of the exercises. Taking the time to adjust the main components properly makes a significant difference — here is what to focus on.
Footbar position
The footbar is one of the main points of contact during reformer work and affects almost every exercise. It should sit at a height and distance that allows your feet or hands to rest on it naturally without reaching or overextending. A footbar that is too low forces the hip joints into a limited range; too high and it compresses the lower back during exercises like footwork. Most reformers offer two to four footbar positions — experiment to find the setting that keeps the pelvis neutral and the lower back in its natural curve.
Carriage position
Many reformers allow adjustment to the carriage’s starting position via a gear bar. This affects how far the carriage travels during an exercise. For people with shorter legs, a higher gear bar setting reduces the initial distance between the footbar and the shoulder blocks, preventing overreaching. For taller people, a lower setting allows the legs to extend more fully. If you regularly find yourself unable to fully extend or feeling compressed at the start of a movement, the gear bar is the first thing to check.
Headrest
The headrest should support the natural curve of the cervical spine without pushing the chin toward the chest or allowing the neck to overextend backward. For most exercises, a flat or minimally raised headrest is correct. If you are working with tight hamstrings or limited spinal flexion, raising the headrest slightly can make the positions more manageable while you build flexibility. Lower it as your range improves.
Shoulder blocks
Shoulder blocks prevent you from sliding off the carriage when pushing against resistance. They should sit just inside the shoulders — snug enough to provide contact but not so tight that they push the shoulders forward or cause discomfort. If the blocks feel too wide or too narrow, check whether your reformer has width-adjustable blocks (many do) or whether positioning them differently on the carriage rail solves the problem.
Straps
Strap length affects arm and leg exercises directly. Too long, and you lose the resistance at the end of the movement; too short, and you cannot reach the intended range without strain. A good starting point for leg straps is a length where, with feet in the straps and lying flat, there is gentle tension throughout the movement without pulling. For arm exercises, the straps should allow a full extension without slack.
Maintaining your settings
The spring system is a separate layer of customisation that works alongside the physical adjustments described above. For a full guide to setting spring tension for different exercises, see my post on reformer tension adjustment.
Write down your ideal settings — footbar position, gear bar notch, headrest height — and check them at the start of every session. On shared reformers in studios, another person’s settings will likely be different from yours. A quick two-minute setup check before you begin means the rest of the session works properly rather than feeling slightly off throughout. Inspect springs and straps periodically for signs of wear, as compromised springs will produce inconsistent resistance regardless of the setting.
