Several major chains, including 24 Hour Fitness and Gold’s Gym, filed for bankruptcy. Blink’s bankruptcy shows the lingering impact of the pandemic on the fitness industry. During the height of the pandemic in 2020, Blink temporarily closed all of its clubs, leaving it without revenue to fund operations. Blink said in its bankruptcy filing that it is still was financially constrained by rent payments it had put off and was still trying to catch up on from the pandemic. An undisclosed number of its clubs are also unprofitable. “It’s a sign that this is an industry still going through growing pains post-Covid,” Rick Caro, the president of fitness industry consulting firm Management Vision, told CNN. The fitness industry faces other challenges, such as consumers cutting back on discretionary spending and the rise of GLP-1 drugs used for weight loss. Luxury gyms such as Life Time are acquiring weight loss clinics with doctors who can prescribe GLP-1s, the powerful new class of medications that has proven to be highly effective at helping people shed weight, while Equinox is designing exercise programs specifically for people taking the medications.
