The Pilates Myth: Can You Really Get Shredded Lying On a Reformer

4 Oct 2025

Let me be clear: I have sweated through every sport imaginable. I know what pain feels like, what it takes to build endurance and strength. And every time someone insists Pilates is the holy grail of being “long and lean,” I wonder if we are all watching the same reality.

Let’s be real: I have never seen anyone step out of a reformer class looking like a shredded Greek statue. Lean? Maybe. Stronger posture? Sure. But shredded? Unless Pilates instructors are sneaking into the squat rack after hours — and I would bet my Apple Watch they do — it is simply not happening.

What Pilates actually does well

I will give Pilates its due: it was invented by Joseph Pilates in the early 20th century for rehabilitation, and it excels in specific areas:

  1. Core stability: EMG (electromyography) studies show that Pilates exercises activate the transverse abdominis and multifidus (deep stabilising muscles of the spine) at higher levels than traditional crunches. Translation: good for posture, less good for biceps.
  2. Posture and mobility: A 2015 meta-analysis in Complementary Therapies in Medicine found Pilates significantly improves flexibility and balance compared to no exercise.
  3. Injury prevention: Especially for lower back issues. It is used in physiotherapy clinics for exactly that reason.
  4. Mind–body connection: Controlled breathing and slow movements reduce stress markers like cortisol, similar to yoga.

In other words, Pilates is a great side dish: it makes you more resilient, mobile, and mindful.

What Pilates doesn’t do (and science backs me up)

Here is where marketing and reality part ways.

  • Calories burned: An average 50-minute Pilates class burns about 175–250 kcal for a 70-kg person (ACE study, 2015). For comparison: running at 10 km/h burns ~600 kcal, cycling hard burns ~900. If your goal is fat loss, Pilates alone is a slow boat to nowhere.
  • Hypertrophy (muscle growth): Hypertrophy requires progressive overload — lifting heavier weights over time, ideally 65–85% of your one-rep max. Pilates uses bodyweight and springs. Great for endurance, not for building big muscle fibers.
  • “Long and lean muscles”: Muscles don’t become “longer.” Their length is genetically set by tendon insertion points. What people mean is “slimmer with less fat,” which comes from… diet. Not Pilates.
  • VO₂ max or cardiovascular health: Pilates is too low-intensity to significantly impact aerobic capacity. Cardio still wins.

That is why most instructors who look “fit” also lift weights, run, or train in other ways. Pilates is part of their recipe, not the whole cookbook.

The reformer: Torture bed or secret weapon?

Ah, the reformer — that intimidating machine with springs and straps that looks like Fifty Shades of Joseph Pilates. It does add resistance, which increases muscle recruitment. Some studies show reformer-based Pilates improves muscular endurance more than mat classes. But still, the load is limited. You will get tone and endurance in stabilising muscles, but not hypertrophy.

Think of it like flossing: a great habit, makes you feel virtuous, but no one ever transformed their body on flossing alone.

Why Pilates persists as the “lean secret”

Because it sells a dream: minimal sweat, graceful movements, and a promise that you will look like a dancer. It is aspirational, marketable, Instagrammable. No one is filming themselves grunting under a barbell for the ‘gram — but reformer stretches with mood lighting? Content gold.

It is also popular because it feels accessible. Many people intimidated by gyms find comfort in a calm Pilates studio. And that isn’t a scam — accessibility matters. But selling it as a standalone solution for fat loss or shredded abs is.

The balanced verdict

  • So, scam or not? Half and half.
  • If you are promised that Pilates alone will make you lean, shredded, and beach-ready — that is marketing fiction.
  • If you are looking for posture, injury prevention, mobility, and a stronger core — Pilates delivers exactly that.

The truth is:

  • Lift weights for muscle and bone health.
  • Do cardio for calorie burn and endurance.
  • Do Pilates (or yoga) for mobility, core stability, and recovery.

It isn’t the main course — it is the side salad. Nice to have, but you won’t survive on it.

Personally, I will still roll my eyes when someone says they got “shredded” from Pilates. But I will also admit that one class a week could save me from tight hips after 9 hours on a bike.

So yes — Pilates has value. But if you want to look like Chris Hemsworth or Gal Gadot, don’t expect a reformer bed to do the work. You will still need dumbbells, sweat, and probably a very boring set of squats.

Because bodies don’t lie, even if fitness marketing sometimes does.
