CoreStrong is the first and only studio in the Treasure Valley offering the Lagree Method on the unique and innovative Megaformer. Designed by celebrity fitness guru Sebastien Lagree, the patented Lagree Fitness workout integrates the key elements of resistance and counter-resistance in a sequence that allows for periods of zero gravity at peak muscle contraction. The workout strengthens the body, tones and elongates the muscles, improves endurance, jump-starts the metabolism, burns fat, increases flexibility and postural alignment, and restores the body’s natural balance…all done quickly and safely.

With no more than 10 clients at a time, CoreStrong is a class-based fitness studio, offering a non-intimidating environment and a workout unlike anything you have ever done before. Our teachers give you personalized and in-depth instruction, pay close attention to your form, and guide you through an intense and effective full-body routine. Your heart rate will increase, you will sweat, and your muscles will shake…

...that’s how you will get into the best shape of your life in only 40 minutes!
