How do springs influence reformer exercise intensity, and what should you monitor as a client progresses?

• A. Springs determine the pace of movement rather than resistance; monitor heart rate.
• B. Springs have no impact on intensity; monitor nothing.
• C. Springs provide resistance; monitor form, range, spinal control, and adjust tension gradually.
• D. Springs limit the exercise to beginners; monitor breathing only.

Answer: (C)

Springs provide resistance, so the load you work against on the reformer is determined by spring tension. As a client progresses, what matters is movement quality under that load: keep an eye on form and alignment, the available range of motion, and especially spinal control throughout each exercise. When technique stays solid and the range can be achieved with control, you can gradually increase the spring tension to raise the challenge. If form falters, range narrows, or the spine loses neutral control, dial back to lighter springs and rebuild stability first. Breathing matters for timing and effort, but it isn’t the primary gauge of intensity—the focus should remain on controlled, progressive loading through careful spring adjustments.
