“I LOVE CORE40 – it’s changed my life and how I work out. I never thought I’d be a morning workout person but I’ve been doing the 6am core40 ramped classes for weeks now and I love it. I love that it’s only 40 minutes but packed with intensity.

I have a tendency to shy away from workout classes because it seems too drawn out and I tend to get bored pretty easily. The 40 minute cadence and pacing of this class is just PERFECT.”

“I’ve only been to CORE40 a few times and I’m already hooked. The machines can seem kind of intimidating, but the staff is always more than happy to explain the machines and what each part is for. The studio is always well kept, with nice bathrooms, cubbies, etc.

The workouts kick my butt in the best possible way, and I have already noticed myself becoming stronger! I’m sure I’ll be back many more times!”
