‘I tried a 15-minute Pilates core routine for 14 Days — and my posture isn’t the only change.’
Low-impact, equipment-free, and easy to stick with — this routine should definitely be on your radar
When it comes to building core strength, I always turn to Pilates. Without fail, all of my Pilates workouts engage the deep core muscles — the ones responsible for stability, posture, and efficient movement that regular ab workouts don’t always reach. Joseph Pilates literally called the core the “powerhouse” of the body, a message we can see reflected in the best Pilates moves for the core.
I was intrigued when I came across a 15-minute, core-focused Pilates routine from instructor Lottie Murphy. Short enough to fit into busy days, and designed to be done daily, it felt like a realistic way to stay consistent without overthinking my workouts. No equipment, no long warm-up, and no excuse not to show up.
I’ve been trying Murphy’s 15-minute core-focused Pilates routine for two weeks now, and while it didn’t leave me drenched in sweat or sore in the way a heavy gym session might, I did notice a few key takeaways.
What is the routine?
This routine is a 15-minute, mat-based Pilates workout that moves through some of Murphy’s go-to exercises for building deep, functional core strength. It’s short, but it doesn’t waste any time — the flow keeps you moving continuously, with little rest between exercises.
Throughout the session, Murphy cues engagement of the transverse abdominis, obliques, and both the upper and lower abs, encouraging that signature Pilates focus on control and precision over rushing through reps. You work through a mix of static holds and slow, controlled movements, including hovering on all fours with the knees lifted, pelvic rocks, plank-to-pike transitions, leg lifts, pulses, and a plank held with the classic Pilates posture.
What I liked most was that the routine never felt repetitive, despite the short time frame. You’re constantly changing position, which keeps different parts of the core firing and helps prevent fatigue in any one area. It’s challenging, without feeling overwhelming.
Below are the three key takeaways I’ve noticed from practicing this routine for two weeks.

1. My deep core felt stronger — not just “worked”
Rather than chasing a dramatic ab burn, this routine made me much more aware of my deep core muscles — especially the transverse abdominis, which sit in the midsection of the core from ribs to pelvis. Over the course of two weeks, I became more aware of when these muscles were switched on.
Moves like hovering on all fours or controlled roll-ups required slow, intentional engagement, rather than momentum. By the end of the fortnight, I felt more stable during planks and twists, and less tempted to grip or brace through my stomach to “cheat” my way through the harder sections. It felt like smarter core work — quieter and more controlled, but ultimately, more effective.
2. It improved my posture and body awareness beyond the mat
A slightly more unexpected benefit was how this routine influenced my body awareness throughout the day. Murphy cues alignment constantly — spine long, pelvis stable, belly button to navel — and those reminders stuck with me after I’d rolled up my mat.
Instead of slumping or over-arching throughout the day (which I’m almost always guilty of doing), I was more conscious of how I was holding myself. My core felt like it was doing some of the work for me, which was a reminder that a strong core isn’t just about how you look or what you can do on the mat — it’s about how you move, sit, and stand every day.
3. Fifteen minutes felt sustainable
Perhaps the biggest win was how easy this routine was to stick to. Fifteen minutes is short enough to feel manageable, even on busy days, but long enough to feel purposeful. There were no excuses — I could fit it in first thing in the morning, after work, or even as a quick reset between tasks.
Because the routine was designed to be done daily, it never felt overly fatiguing. Instead of dreading it, I looked forward to the consistency. Over two weeks, that regularity added up, and it reminded me that progress doesn’t always come from longer or harder workouts — sometimes it’s the ones you can return to day after day that make the biggest difference.
Verdict: Is this Pilates core routine worth trying?
Suffice to say that after two weeks, I’m convinced this 15-minute Pilates routine is a smart addition to a well-rounded fitness routine. It didn’t leave me exhausted or sore, but it did help me build deeper core strength, improve my posture, and feel more connected to how I move throughout the day. If you’re looking for a short, sustainable way to strengthen your core without hammering your body, this is absolutely worth a try.
