The Top 5 Reasons Your Core
Isn't Getting Stronger —
No Matter How Much Pilates You Do.

Most people hear "core" and immediately think abs. So they do endless reps targeting the six-pack muscle — the rectus abdominis — and wonder why nothing changes in how they feel or how they move.

But your real core is deeper than that. It is a whole system working together — and if you are not accessing it first, your body will find another way to get the job done. Usually the wrong muscles doing a job they were never designed to do.

This is a big one — and it is far more common than most people realize.

If your pelvis is tilted forward — which is called anterior pelvic tilt and is one of the most common postural patterns I see in the studio — your deep core is already in a lengthened and inhibited position before you even start moving. So when you try to engage your core nothing really happens.

Until your alignment is corrected your core simply cannot do its job — no matter how many reps you do or how hard you try to engage it. This is exactly why every session at Function Pilates begins with a postural assessment. Because the position of the body determines what is actually possible.

When your core is not doing its job your body does not just give up. It compensates. And your hip flexors are more than happy to step in — they are strong, they are motivated, and they will take over any exercise that asks for spinal stability if the deep system is not engaged first.

The problem is they are not supposed to be doing that job. So you end up doing the exercise, feeling like you worked hard, but your core never actually engaged. And the more this happens the more your body defaults to that compensation pattern.

Overactive hip flexors also directly inhibit glute activation — which means the longer this pattern continues the weaker both your core and your glutes become. It is a cycle that does not fix itself on its own. It needs to be identified and addressed directly.

Your breath is not just a cue to help you relax. It is the actual mechanism through which your deep core activates. This is one of the most important things to understand about Pilates — and one of the most commonly overlooked.

If you are holding your breath, rushing through exercises, or not intentionally connecting your breath to your movement — you are bypassing the entire foundation of core work. The most advanced Pilates exercise in the world does nothing for your deep stabilizers if the breath is not driving the activation first.

If every session looks the same — same exercises, same order, same level — your body will adapt. And once your body adapts it stops being challenged. That is where progress stops.

Real core strength requires progression, intention, and programming that is actually specific to your body. Not just doing more of the same thing.

This is the difference between a generic Pilates class and a session built around a postural assessment. When the program is designed around where your body actually is — your compensation patterns, your alignment, your specific strengths and weaknesses — every exercise has a purpose and every session moves you forward.
