Anatomy & Biomechanics: Muscles Targeted in Reformer Pilates

Reformer Pilates is renowned for its ability to strengthen, lengthen, and stabilise the body through controlled, precise movements. Unlike traditional workouts, which often isolate muscles, Reformer Pilates focuses on functional movement patterns, improving overall biomechanics and posture. Understanding the muscles targeted in common Reformer exercises can help you maximise your practice and achieve better results.

1. Core Activation: The Foundation of Reformer Pilates

The core is the powerhouse of every Pilates movement. Strong core muscles provide stability, protect the spine, and enhance movement efficiency.

🔹 Muscles Worked:

• Rectus Abdominis (front of the abdomen, "six-pack" muscle)
• Transverse Abdominis (deep core stabiliser)
• Obliques (rotation and side-bending)
• Multifidus & Erector Spinae (spinal support and posture)

🔹 Key Exercise: The Hundred

• Strengthens the deep core muscles and improves endurance.
• Engages the abdominals while maintaining a neutral spine.

2. Lower Body Strength & Stability

Reformer Pilates effectively targets the legs and glutes, improving strength, balance, and coordination.

🔹 Muscles Worked:

• Gluteus Maximus, Medius & Minimus (hip stability and power)
• Quadriceps (front of the thigh, knee extension)
• Hamstrings (back of the thigh, hip extension)
• Adductors & Abductors (inner and outer thighs, leg control)

🔹 Key Exercise: Footwork on the Reformer

• Engages the quads, hamstrings, and glutes while improving alignment.
• Builds lower body endurance and supports knee stability.

3. Upper Body Strength & Posture Support

Unlike traditional weightlifting, Reformer Pilates uses controlled resistance to sculpt the arms, shoulders, and back without strain.

🔹 Muscles Worked:

• Deltoids & Rotator Cuff Muscles (shoulder mobility and stability)
• Latissimus Dorsi (back strength and posture)
• Triceps & Biceps (arm strength and endurance)
• Trapezius & Rhomboids (scapular stability and upper back support)

🔹 Key Exercise: Seated Arm Work with Straps

• Enhances shoulder stability and arm strength with controlled resistance.
• Supports better posture and upper body alignment.

4. Spinal Mobility & Flexibility

A mobile, healthy spine is essential for functional movement and injury prevention. Reformer Pilates focuses on spinal articulation and controlled flexibility.

🔹 Muscles Worked:

• Erector Spinae & Multifidus (spinal extension and posture)
• Obliques & Rectus Abdominis (spinal rotation and flexion)
• Hip Flexors (support hip mobility and spinal positioning)

🔹 Key Exercise: Short Spine Massage

• Promotes spinal flexibility and core control.
• Encourages smooth, controlled movement through the vertebrae.

5. Full-Body Integration & Functional Movement

Reformer Pilates is designed to integrate multiple muscle groups for efficient, balanced movement. Exercises challenge coordination, stability, and endurance.

🔹 Key Exercise: Long Stretch Series

• Works the core, shoulders, legs, and back simultaneously.
• Builds strength, balance, and control through a full-body dynamic movement.

Understanding the muscles worked in Reformer Pilates helps you refine your technique, improve biomechanics, and maximise your workout results. Whether you’re aiming to build strength, enhance flexibility, or support injury recovery, Pilates provides a holistic approach to movement.
