WHOOP buys Train Fitness to put rep-counting in a $10.1B platform
What's the deal? WHOOP has acquired Train FitnessDealroom has a profile for this one. Try Dealroom →, the Toronto maker of an Apple Watch app that counts gym reps from wrist motion alone. Terms were not disclosed. Neither company has formally announced the deal, which surfaced on the LinkedIn profiles of three Train Fitness staff.
What does Train Fitness do? Its app recognises more than 470 exercises and counts reps per set using Apple Watch motion, removing manual logging. The company says more than 100,000 lifters use it, and that its recognition method is patented.
What's the endgame? The likely prize is the technology behind the app: the exercise-recognition models, the patent, and the team. WHOOP's 5.0 and MG bands already carry motion sensors, so rep counting could move from the watch to WHOOP's own strap.
Why now? WHOOP has deep-pocketed momentum, having raised $575 million in March at a $10.1 billion valuation. It ended 2025 cash-flow positive, with a $1.1 billion annual revenue run rate and more than 2.5 million members.
The deal echoes WHOOP's 2021 purchase of PUSHDealroom has a profile for this one. Try Dealroom →, a Canadian strength-tracking company, which it folded into its platform. Both acquisitions point to a push to make strength tracking part of its recovery-and-fitness offering.
What could go wrong? Cheaper screenless rivals are crowding in without WHOOP's compulsory subscription, including Fitbit Air at $99.99 and Garmin CIRQA at $199.99. Apple is also sharpening its health features and reportedly exploring a screenless tracker aimed at WHOOP's market.
The signal: Rather than cut costs as competition intensifies, WHOOP is buying to add features. The move suggests the company sees strength tracking — long a gap in wearable workout data — as the next battleground in fitness hardware.
