About [solidcore]

[solidcore] is unlike any workout you’ve ever done before. It’s a high-intensity, low-impact 50-minute session that is done as slow as possible to lengthen and tone your body. Don’t let the slow fool you… it’s hard. You can expect a full–body session using controlled movements on a resistance-based machine to work your slow and fast-twitch muscles to the point of failure. With countless variations of moves stemming from planks, lunges and squats, your body and mind will be challenged in each and every class.

What people are saying

For me, what separates [solidcore] from other studios or gyms is the atmosphere. The workouts humble ultra-marathoners just as much as forty-something moms trying to get their groove back, but more importantly, there is no competitive "scene" or attitude about the folks who come here. No one feels out of place, no one feels judged. I think the fact that everyone feels extremely challenged--regardless of their fitness level going in--is part of why it is such a unique and positive culture. That, and we're all so relieved we survived each class we just want to hug each other.

I never felt like a customer. From the beginning, the coaches have felt like friends... friends who push you to new heights.

[solidcore] is the best and most challenging workout I've experienced! Since taking my first class in March, I've formed relationships with coaches who continuously push me physically and mentally beyond my limits. As a runner, it's great to have a strength training class that takes the impact off my joints while still sculpting my legs and core. I encourage everyone to try [solidcore] at least once - you will be addicted.
