The 7 Most Common Mistakes When Starting Pilates Reformer (and How to Correct Them)
Starting with the Pilates Reformer is exciting: you immediately notice how your core works, how your muscles lengthen, and how your posture improves from the first few sessions. But it is also a technical discipline, and the first few months are when mistakes are made that later become harder to correct. If you practice in a studio or have set up your reformer at home, knowing these common pitfalls will help you progress faster and avoid unnecessary discomfort.
1. Holding Spring Tension with the Wrong Body Part
One of the most frequent mistakes is compensating for the spring resistance with your arms or neck instead of your core. The Reformer is designed for the force to come from your abdomen, pelvic floor, and glutes; your arms and legs are merely the channels through which that force is transmitted to the carriage. If you notice tension in your trapezius or neck at the end of each repetition, it's a sign that your core isn't doing its job.
How to correct it: Before each exercise, engage your abdomen by imagining drawing your navel towards your spine and maintain that activation throughout the entire movement, not just at the start.
2. Choosing Incorrect Spring Tension
Too much tension forces you to compensate with momentum and poor technique; too little tension causes the carriage to move uncontrollably and you lose stability. Both extremes increase the risk of injury and hinder your real progress.
How to correct it: In the first few months, always prioritize quality of movement over resistance. If you can't control the carriage smoothly in both directions, remove a spring.
3. Holding Your Breath
It's common to hold your breath during exertion, especially in intense leg or abdominal exercises. This creates unnecessary tension and reduces your ability to stabilize your torso, which largely depends on correct lateral breathing.
How to correct it: Practice costal breathing – inhaling to prepare for the movement and exhaling during exertion – off the Reformer, with mat exercises, until it becomes automatic.
4. Losing Grip and Slipping on the Platform
In practice, this is the mistake that most interrupts a session. As the class progresses, the body sweats, the platform becomes damp, and feet or hands start to slip, especially in standing exercises or plank positions on the carriage. Besides being uncomfortable, involuntary sliding breaks the alignment that is so hard to maintain and can cause sudden compensations in knees or wrists.
How to correct it: Always maintain a dry and stable contact point. Many advanced practitioners solve this by placing a non-slip towel on the carriage, which absorbs sweat and prevents micro-slipping without needing to interrupt the session to dry the surface.
5. Going Too Fast
The Reformer invites you to pick up rhythm because the carriage movement generates inertia, but excessive speed often means you're using momentum instead of muscle control. This is one reason why two people can do "the same exercise" and get very different results.
How to correct it: Mentally count the timing of each phase (for example, 2 seconds out and 3 seconds back) until a slow pace becomes your natural speed.
6. Neglecting Pelvic Alignment
Many Reformer exercises, especially leg exercises on the footbar, are performed with incorrect pelvic tilt: the lower back lifts off the carriage or the pelvis rotates to one side. Over time, this can lead to lower back discomfort that has nothing to do with the exercise itself, but rather with its execution.
How to correct it: Find a neutral pelvic position before starting each set and periodically check, especially when fatigue increases, that it hasn't been lost.
7. Not Adapting Exercises to Your Actual Level
Following a routine or video designed for intermediate level when you've only been practicing for a few weeks is a sure way to accumulate bad habits. The Reformer allows for infinite variations of intensity for the same exercise, so there's no reason to force a version that your body doesn't yet control.
How to correct it: Always start with the simplest variation of each movement and only progress when you can execute it with total control, without compensations.
Small Adjustments, Big Results
None of these errors are serious if detected early. The key is to train with attention to detail from the beginning: activating the core before moving the carriage, conscious breathing, maintaining pelvic alignment, and, above all, keeping a good grip at all times so that technique is not compromised by something as simple as sweat on the platform.
Precisely that last point—slipping due to sweat—is one of the most frustrating for those who regularly practice Pilates Reformer, whether in a studio or at home. If you notice you're losing your grip halfway through a session or that you have to stop to dry the carriage, the Bellman Pilates Non-Slip Reformer Towel is designed specifically for this: it fits the carriage, absorbs sweat, and maintains a stable surface throughout the class, so you can concentrate on technique and not on slipping. It's a small accessory that makes a real difference in the quality of each session.
