How to Use Reformer Springs Correctly in Class

The springs are not a setting to “get through.” They are part of the exercise. To use reformer springs correctly, treat resistance as information: it should give you enough support to move with control, enough challenge to create muscular tension, and enough stability to keep your form precise.

On a reformer, more resistance is not automatically better. Nor is a lighter setting always more advanced. The right choice depends on the movement, your body position, the goal of the exercise, and your ability to maintain alignment from the first repetition to the last.

What reformer springs actually do

Reformer springs create resistance as the carriage moves away from its resting position. They can make an exercise feel stronger, steadier, heavier, or more supported. In some movements, springs help you find control. In others, they ask your muscles to work harder to prevent the carriage from moving too quickly.

This is why spring tension needs context. A heavier spring setting may be ideal for footwork, where you press the carriage away with the legs and want a stable base. That same setting may be inappropriate for an arm exercise in straps, where excessive load can pull the shoulders forward or encourage the ribs to flare.

The purpose is never simply to move the carriage. It is to create controlled movement under tension. At Reformer Club, this is central to Slow Resistance Training: moving with intention, staying present through the effort, and building endurance without sacrificing form.

How to use reformer springs correctly for each exercise

Start with the spring setting given by your instructor. It is selected for the sequence, the equipment setup, and the intended training effect. Spring colours and resistance levels can vary between reformer brands, so avoid assuming that a colour means the same thing everywhere. Learn the system on the machine you are using.

Then pay attention to what the setting allows you to do. The right tension should let you begin and finish the movement with control. You should be able to keep your breath steady, your joints organised, and your range of motion intentional. Effort is expected. Losing your shape is a signal to adjust.

For a lower-body exercise such as footwork, enough resistance can help you connect through the feet, legs, glutes, and centre. If the carriage feels unstable or races home as you bend your knees, the load may be too light for the movement. If you cannot fully extend and return without locking the knees, gripping the hips, or lifting the pelvis, it may be too heavy.

In strap work, lighter springs can create a different kind of demand. They require you to stabilise the carriage while organising the shoulders and trunk. But light does not mean easy. If the straps pull your shoulders up towards your ears, your ribs lift away from the carriage, or your wrists take over, reduce the range, choose more support, or ask for guidance.

Standing and kneeling exercises are particularly sensitive to spring selection. Here, the springs influence balance as much as strength. Too little tension can make the carriage feel unpredictable. Too much can force you to brace, rush, or compensate. The goal is a setting that allows your legs, core, and upper body to work together rather than fight the machine.

More spring tension is not always more effective

The temptation to add springs is understandable. More load can feel like more work. Yet the most productive resistance is the amount you can control through the entire exercise.

A heavy setting can be useful when it supports a strong, grounded pattern. It can also hide compensation. You may push with momentum, grip through the lower back, or recruit larger muscles while losing the deeper control the exercise is designed to build.

A lighter setting can expose instability and demand greater precision. This can be valuable for shoulder control, single-leg work, mobility-focused sequences, and advanced coordination. It can also become too light, causing the carriage to move faster than you can manage.

Think of spring choice as a training variable, not a measure of fitness. Your strongest setting is not necessarily your most intelligent one. The best setting is the one that creates meaningful tension while you remain steady, aligned, and connected to your breath.

Signs your resistance needs attention

Your body usually gives clear feedback. If you need to hold your breath to complete a repetition, shorten your movement dramatically, or feel the carriage slam into the stopper, pause and reassess. The same applies if your shoulders creep up, your pelvis shifts, or your knees collapse inward under load.

There are also quieter signs. You may feel the exercise only in your hip flexors when it should be targeting your glutes, or only in your neck during arm work. You may finish a set feeling rushed rather than challenged. These patterns do not mean you have failed. They mean the resistance, range, or setup may need refinement.

A useful check is whether you can control both directions of the carriage. Pressing or pulling out is only half of the work. Returning with control matters just as much. If the springs pull you back faster than you can resist, you are missing the eccentric phase - the lengthening work that builds strength and endurance.

Change springs with care

Spring changes are part of the class flow, but they deserve your full attention. Always bring the carriage fully home before changing springs. Make one adjustment at a time, ensure the spring is securely attached, and confirm the setup before you place weight on the carriage or take the straps.

Never change springs while the carriage is moving or while another person is using the reformer. If you are unsure which spring your instructor indicated, ask. A quick question protects your experience and keeps the session focused.

It is also worth remembering that springs affect how the carriage rests. Removing too much resistance can make the carriage less stable, especially for getting on, getting off, kneeling, or standing. Follow the setup precisely, even when you are familiar with the exercise. Familiarity should build confidence, not shortcuts.

Let your level guide your choices

Beginners often benefit from clearer structure and more support. In a START class, the focus is learning the machine, understanding spring changes, and recognising what controlled effort feels like. There is no advantage in racing ahead of the setup. Precision is progress.

As you move into SIGNATURE or BURN sessions, the spring choices may become more nuanced. You may work with less support, longer time under tension, more unilateral work, or transitions that challenge balance and endurance. Advanced training is not about choosing the lightest or heaviest setting without thought. It is about responding accurately to a more complex demand.

Your ideal spring setting can also change from day to day. Sleep, stress, training history, mobility, and energy levels all influence control. Choosing a more supportive option on one day is not stepping back. It is training with awareness.

Ask for the adjustment that serves your body

A well-taught class offers a framework, not a test of whether every body must use identical resistance. Tell your instructor about pain, injury, pregnancy, recent surgery, or a movement that does not feel right. They can help adapt the spring setting, range, or position while preserving the purpose of the exercise.

Muscular effort, heat, and fatigue are normal. Sharp pain, tingling, joint pain, or a feeling of instability are not signals to push through. Stop, reset, and ask for support. Intelligent training respects the difference.

The most satisfying reformer work happens when resistance and control meet. Let the springs challenge you, but never let them dictate your form. Come as you are, move with focus, and leave feeling stronger, more balanced, and more connected to what your body can do.
