CoreStrong Studios closed until further notice

Your health and wellness is our top priority. After close consideration we have made the difficult decision to close the CoreStrong studios (both Boise and Eagle locations) effective Tuesday, March 17th. We believe that social distancing is a critical preventative measure to stop the spread and flatten the curve of COVID-19, and closing our studios will keep our instructors and clients safe and well.

All auto-pay and unlimited membership accounts will be paused and resumed when the studios re-open and any bookings made from a class pack will be reinstated to your accounts (please be patient, as this may take a week to be credited to your account).

We will keep in close contact via newsletter, social media, push notifications, and the news section of the app to communicate updates.

Additionally, we will be providing in-home workouts via video and streaming service in the coming weeks. (Stay tuned for more information!).

Please don’t hesitate with any questions: .

Be well,

Cathy Iliff and your CoreStrong team

The Workout that Works 

Like nothing you've done before

 get results in days, not months.

CoreStrong is the first and only studio in the Treasure Valley offering the Lagree Method on the unique and innovative Megaformer.

The Lagree Method is a 40-minute, high-intensity, full-body workout on the Megaformer. The method integrates all elements of physical fitness (cardio, strength, endurance, and flexibility) and will help you build strength, carve long-lean muscles, and see changes in your physique in days, not months.

With no more than 10 clients at a time, we offer a non-intimidating environment and a workout unlike anything you have ever done before. Our instructors give you personalized and in-depth instruction, individual attention on your form, and guide you through an intense and effective full-body routine.




A workout that creates maximum benefits, in the least amount of time. This is a 40-minute, full body workout, that uses slow, controlled movements to fire up your slow-twitch, fat-burning muscles, ignite your metabolism, elevate your heart rate, and get you sweating. The workout is adaptable to all fitness levels. This patented method is the most innovative and aggressive approach to full body conditioning.





Expect to burn up to 600 calories per session and to continue burning calories between classes, as Lagree Fitness maximizes EPOC (excess post-exercise oxygen consumption). In other words, your body becomes a fat burning machine for more than 24 hours after you’ve trained! Results can be seen (and felt) within the first few sessions: obliques become more visible, glutes are lifted, abs are flattened. And who doesn’t want that?





The Lagree Fitness Method is built around the concept of effective muscle stimulation, which occurs when muscles are under constant tension and worked to the point of exhaustion, giving you that long, lean and sculpted look. With hundreds of moves and resistance options, no workout is ever the same, so you will not get bored, your body will stay constantly challenged, you won’t plateau, and the results you desire happen that much faster.
