Who we are [solidcore] is a national boutique fitness company with 100+ studios across the country. Our signature workout is 50 minutes of low-impact, high-intensity strength training: the lights are low and the music is loud. The coach guides the class through a series of slow & controlled movements that are sequenced to work muscles to failure. This class is accessible for all fitness levels and can be amplified or modified to accommodate individual goals. Class is as intense as our reviews suggest, but our instructors go above and beyond to provide a welcoming, supportive, empowering, and challenging experience for all.
