Is the Reformer Really the Pilates “Workhorse”? (Spoiler: Yes—But It Depends on Your Goals)
It’s versatile enough to replicate nearly every mat exercise—and add resistance, support, or challenge to them (e.g., mat roll-ups become reformer roll-ups with spring tension for core strength).
It’s the most commonly taught piece in teacher training programs—mastering the reformer means you’ll be prepared for the bulk of your certification coursework.
It’s accessible to all levels: beginners can use light springs for support, while advanced practitioners can amp up resistance for strength work.

Key Differences: Body Effects of Reformer vs. Cadillac vs. Pilates Chair
| Equipment | Core Body Effects | Best For | Unique Benefits |
|---|---|---|---|
| Reformer | - Builds controlled, functional strength (especially core, glutes, and posterior chain)- Improves spinal mobility (via moves like reformer spine twists and open leg rockers)- Enhances mind-muscle connection (spring resistance forces you to engage stabilizer muscles to avoid over-swinging the carriage)- Lowers joint strain (carriage support reduces impact on knees/hips compared to mat work) | Teacher training prep, full-body strength, mobility for desk-bound bodies, injury rehab | The only piece that lets you do both supportive moves (e.g., assisted roll-ups for tight spines) and resistive moves (e.g., leg presses for glute strength)—critical for teaching diverse clients. |
| Cadillac (a.k.a. Trapeze Table) | - Boosts upper body strength and shoulder mobility (via trapeze arm pulls, push-ups, and shoulder circles)- Improves spinal extension (moves like swan dives and back bends on the Cadillac are gentler than mat back bends)- Challenges core stability (suspension from trapeze straps forces your core to engage to keep your body aligned)- Enhances balance and coordination (unstable trapeze positions require full-body control) | Shoulder mobility, spinal extension work, advanced balance moves, adding variety to mat practice | The Cadillac is the best piece for reversing rounded-shoulder posture—a huge win for anyone with desk habits. It’s also the most “fun” piece for advanced moves (e.g., aerial Pilates-style poses). |
| Pilates Chair (a.k.a. Wunda Chair) | - Targets small, underused stabilizer muscles (e.g., glute medius, inner thighs, and deep core muscles)- Builds power and agility (spring-loaded seat challenges you to move with speed and control)- Improves hip mobility (moves like chair squats and hip circles target tight hip flexors)- Isolates leg and glute strength (small range of motion means you can’t rely on momentum—only muscle engagement) | Isolated strength work, hip mobility, quick 15-minute workouts, supplementing reformer/Cadillac practice | The chair is compact, portable, and perfect for targeted problem areas (e.g., weak glutes or tight inner thighs). It’s great for adding quick strength drills to your routine. |
