Your 14-day core challenge starts 4th May.
If you train regularly but feel like your core isn’t keeping up, this is where you fix it.
Killer Core Commitment 2.0 is a focused 14-day Pilates challenge designed to train your core properly. Not just the front of your body, but the full system that supports how you move, lift and train.
Across two weeks, you’ll work through targeted sessions for upper abs, lower abs, obliques, back and glutes. Everything is designed to build strength, control and endurance across the entire core.
No random workouts. No filler. Just structured, intelligent training that challenges you properly. This is your chance to build a core that actually performs.
Build strength that carries into summer.
→ STARTING 4TH MAY
Stronger core
Better movement
More control under load
14 days. Fully structured. Designed to challenge. Not for beginners.
Why this challenge works.
Most people train their abs and hope for the best.
But your core is more than that.
It’s a system — abs, obliques, deep core, back and glutes — all working together to create tension, manage load and support how you move.
That’s what this challenge trains.
→ No random classes.
→ No guesswork.
→ No wasted effort.
Just a clear, structured plan that builds the kind of strength that actually carries into your training and your life.
By the end of the 14 days, expect to feel:
-
→ Stronger through your core
-
→ More stable and switched on in your training
-
→ Better supported in your posture and movement
-
→ More control and tension through your core
-
→ More connected through your glutes and back
-
→ More confident in how your body moves
Who it’s for.
This is not beginner Pilates. It’s designed for people who train hard and expect to be challenged.
