Solidcore (stylized as [solidcore]) is a fitness enterprise headquartered in Rosslyn, Virginia, with a network exceeding 160 studios throughout the United States. Established in 2013 in Washington, D.C., the company focuses on full-body strength workouts utilizing specially designed reformer machines.
History
[solidcore] was created by Anne Mahlum in November 2013, opening its inaugural studio in Washington, D.C.'s Adams Morgan district. Initially managed from Mahlum's residence, the brand grew to encompass 100 locations following investments from Kohlberg & Company and VMG Partners.
In 2021, Bryan Myers assumed the roles of president and CEO, distinguishing himself as one of the few Black and LGBTQ+ leaders heading a prominent U.S. fitness firm. Myers joined [solidcore] in 2017 after previous positions at Sweetgreen, where he directed the company's nationwide growth and operational strategies.
The company received accolades in 2024 when Good Housekeeping awarded it ‘Best Pilates-Inspired Studio,’ and in 2025, Well & Good honored it as “Best Inclusive Gym.”
In September 2024, global investment firm L Catterton acquired a controlling interest in [solidcore]. The following year, the company collaborated with wearable technology provider WHOOP to offer insights into how workouts influence recovery and athletic performance.
Social responsibility
In 2019, [solidcore] introduced a "Pay It Forward" membership option that allows members to sponsor memberships for underserved communities, such as LGBTQ+ youth and those recuperating from chronic illnesses.
Amid the COVID-19 crisis, [solidcore] extended complimentary virtual classes to healthcare professionals and first responders nationwide, engaging over 15,000 participants during 2020.
Classes
[solidcore]'s workout sessions incorporate a proprietary resistance apparatus designed to maintain continuous muscle tension, thereby improving muscular stamina and core strength. Each class initiates with a core-centric warm-up and progresses through an organized routine targeting multiple muscle groups. The exercises are conducted in studios illuminated by subdued blue lighting, emphasizing precise, high-intensity movements aimed at muscular fatigue.
The brand has attracted attention partly due to endorsements from notable personalities including Michelle Obama, Sydney Sweeney, and Vanessa Hudgens.
