Everyone say hello to one of our Amsterdam trainers, Poppy!

Poppy’s love of fitness began in the Muay Thai boxing gyms of Thailand, where movement, discipline, and pushing physical limits sparked a lifelong passion for training. She has spent 30 years coaching across Thailand, London, Brighton, and now Amsterdam in a wide variety of disciplines, including HIIT, kick boxing, aerobics, and disability & fitness.

She loves the Lagree Fitness method and the CORE40 community, and also brings her energy to the VersaClimber as an instructor at ASCEND.

Passionate about inclusive, accessible fitness, Poppy is known for her motivating energy, sharp eye for form, and commitment to helping every client move well and feel strong!

Our Co-Founder doesn’t coach for comfort.

Each class carries a level of intensity that pushes people beyond their perceived limits — where real strength is built, mentally and physically.

This is Transformational Fitness in action.

That post-class feeling: shaking, sweaty, and smiling anyway.

This is your reminder that shaking means you’re working. The struggle means you’re getting stronger. You’re capable of way more than you think.

At CORE40, we’re here to show you what’s possible when you don’t give up.

Comfort zones don’t build strength. Intentional choices do. So when your instructor cues a Mega Donkey Kick, consider it an invitation to level up your Lagree practice.

Explore this variation in your next class and notice the difference!
