15 Common Pilates Reformer Mistakes and How to Fix Them

Pilates reformer exercises are designed around control, alignment, breathing, and intentional movement. But even experienced users can develop habits that reduce the effectiveness of an exercise or place unnecessary stress on the body.

Whether you practice Pilates at home or in a professional studio, learning to recognize common reformer mistakes can help you move more confidently and get more from every session.

1. Using Too Much Spring Resistance

More resistance does not always mean a better workout. Using springs that are too heavy can cause you to rely on momentum or larger muscle groups instead of maintaining proper control and technique.

Try instead: Choose resistance that allows you to complete the full movement smoothly while maintaining good alignment.

2. Using Too Little Resistance

Too little spring resistance can also create problems. During standing or stability exercises, a carriage that moves too freely may be difficult to control.

Try instead: Select enough resistance to support stability while still allowing controlled movement.

3. Letting the Carriage Slam Closed

One of the most common reformer mistakes is allowing the springs to pull the carriage back quickly at the end of a repetition.

Try instead: Control both directions of the exercise. The return movement is just as important as the push or pull.

4. Incorrect Footbar Setup

The footbar position can change depending on the exercise, body proportions, and reformer model. An incorrectly positioned or unsecured footbar can affect comfort and alignment.

Try instead: Confirm that the footbar is fully secured and positioned correctly before beginning an exercise.

5. Incorrect Jumpboard Installation

Before starting jumping exercises, the jumpboard should be positioned and secured according to the reformer's instructions.

Try instead: Check the jumpboard connection and stability before placing your feet against it.

6. Overarching the Lower Back

Overarching is especially common during bridges, feet-in-straps exercises, and movements involving hip extension.

Try instead: Keep the ribs connected, engage the core, and focus on maintaining appropriate spinal alignment rather than trying to create a larger movement.

7. Letting the Shoulders Rise Toward the Ears

During arm exercises, rowing, pulling straps, and abdominal work, users sometimes tense the neck and lift the shoulders.

Try instead: Keep the shoulders relaxed and away from the ears while maintaining length through the neck.

8. Moving Too Quickly

Speed can turn a controlled Pilates exercise into a momentum-based movement.

Try instead: Slow down and focus on smooth, deliberate movement. Aim to control the carriage throughout the entire range.

9. Locking the Knees

Hyperextending or locking the knees can happen during footwork and standing exercises.

Try instead: Maintain control through the legs and avoid forcing the knees into an overly extended position.

10. Losing Pelvic and Spinal Control

The pelvis may tilt or rotate unintentionally as the carriage moves, especially when an exercise becomes challenging.

Try instead: Reduce the range of motion or adjust the resistance until you can maintain better control.

11. Pulling With the Neck During Abdominal Exercises

During abdominal work, some users try to lift higher by pulling the head and neck forward.

Try instead: Allow the abdominal muscles to initiate the movement while keeping the neck long and supported.

12. Using the Wrong Strap or Rope Length

Straps that are too long or too short can change the starting position and make an exercise uncomfortable.

Try instead: Adjust the straps according to the exercise and your body proportions before beginning.

13. Using One Side More Than the Other

It is common to unknowingly push harder with one leg or pull more strongly with one arm.

Try instead: Pay attention to whether the carriage remains level and whether both sides of your body are contributing evenly.

14. Looking Down During Standing Exercises

Watching the carriage constantly can cause the head and shoulders to move forward and may change overall posture.

Try instead: Once you feel stable, keep your gaze forward or follow the direction recommended for the exercise.

15. Getting On or Off While the Carriage Is Moving

Transitions deserve the same attention as the exercises themselves. Stepping onto or away from an unstable carriage can make the movement unpredictable.

Try instead: Stabilize the carriage first and use the reformer's recommended setup before transitioning.
