Core
Core muscles — deep abdominals, obliques, and related stabilisers — coordinate breathing, bracing, and spinal control during reformer work. A responsive core helps you manage carriage movement, maintain alignment in flexion and extension, and transfer load between upper and lower body. Core engagement is central to most exercises in the library, from Hundred Prep and footwork to long stretch and chair progressions. The goal is steady, distributed tension rather than gripping. Build foundation with supine and seated patterns that teach rib-to-hip connection before advanced flexion, extension, or rotation challenges.

FAQs
What counts as core work on the reformer?
Deep abdominal and oblique engagement that stabilises the trunk while the carriage moves — seen in footwork, Hundred Prep, strap work, and many flexion patterns.
Is core strength the same as core stability?
Strength and stability overlap on the reformer. Stability is often trained first through bracing and breath before harder flexion or spring load.
