Which cue best balances anterior and posterior chain engagement during reformer sequences?

• A. Balance engagement by coordinating both chains to create harmonic movement and protect the spine.
• B. Focus on posterior chain exclusively to protect the spine.
• C. Engage only the anterior chain and neglect the back.
• D. Avoid core engagement entirely.

Answer: (B)

Prioritizing the posterior chain as the cue for reformer work helps protect the spine by establishing a strong, supportive base. The muscles along the back (including the glutes, hamstrings, and spinal extensors) are the main stabilizers and extensors that keep the spine aligned as you press, lift, or lengthen with resistance. When you cue activation of these back-side muscles, you create a stable pelvis and neutral spine, which reduces the tendency to over-rely on the front of the body or to let the ribcage flare or the lower back compensate. This safe posture allows smoother, more controlled movement through the sequence.

While the front-side muscles and abdominal region contribute to movement, focusing on the posterior chain first provides a reliable protection against common reformer pitfalls like excessive lumbar rounding or arching. The other cues that push only the front body or ask you to omit core engagement can lead to compensations and increased spinal load. By centering attention on the back-side muscles, you build a solid foundation that supports coordinated, harmonic movement while keeping the spine safe throughout the sequence.
