Fort Finally Made a Wearable That Takes Strength Training as Seriously as Cardio

The Macro: Wearables Track Everything Except What Lifters Actually Care About

The wearable fitness market is massive but has a glaring blind spot. Whoop tracks recovery and strain. Garmin tracks running, cycling, and swimming. Oura tracks sleep. But ask any of these devices to tell you how your bench press is progressing, and the answer is essentially nothing useful.

Strength training is the fastest-growing segment of fitness. The longevity research community has made it clear that muscle mass and strength are among the strongest predictors of healthy aging. More people are lifting weights than ever before. Yet the wearable industry has largely ignored them.

The reason is technical. Tracking running is relatively simple: accelerometer data plus GPS gives you speed, distance, and cadence. Tracking strength training requires identifying which exercise you are doing, counting reps, measuring rep velocity, tracking time under tension, and estimating proximity to failure. These metrics require more sophisticated motion analysis and exercise recognition.

Existing wearables technically let you log strength workouts, but the process is manual. You select the exercise, enter the weight, count reps yourself, and tap buttons between sets. Nobody does this consistently because it is tedious and interrupts the workout.

Fort, backed by Y Combinator, is the first wearable built to automatically track strength training. No manual logging. No tapping between sets. Put it on and lift.

The Micro: Pre-Orders at $289 and Shipping Q3 2026

Miranda Nover (CEO), Paul Schneider, and Zac Valles (CPO) cofounded Fort with backing from YC, Carnegie Mellon University, Afore Capital, Weekend Fund, and angel investors from notable companies.

The device uses heart rate and motion data to automatically detect exercises, count reps, and provide muscle-level insights. Metrics include session scores, rep velocity, time under tension, and proximity to failure. These are the metrics that serious lifters track manually in notebooks or apps like Strong and Hevy.

The hardware specs are competitive: 7-day battery life, interchangeable bands, multiple color options, and compatibility with both iOS and Android. The device attaches via clip or magnet, suggesting flexibility in where users wear it.

Pricing is $289 for pre-order ($319 retail) and includes one year of the app subscription ($79.99/year normally). First shipments target Q3 2026 for US customers.

Fort also tracks cardio, sleep, stress, and recovery. This is smart because it means users do not need to wear Fort alongside another wearable. It handles everything, but strength training is the differentiator that gives people a reason to choose Fort over Whoop or Garmin.

Competitors include Whoop (recovery and strain), Garmin (multi-sport), and various fitness apps that attempt exercise recognition through phone sensors. No existing wearable offers automatic strength training recognition with the depth of metrics Fort promises.

The Verdict

Fort is filling a genuine gap in the wearable market. Strength training is underserved by current devices, and the demand for better tracking is real.

At 30 days after shipping: how accurately does Fort identify exercises and count reps across the full range of common lifts?

At 60 days: are users finding the muscle-level insights actionable, or are they just interesting data without clear guidance?

At 90 days: what is the daily active usage rate? Wearable products live or die on whether people keep wearing them after the novelty fades.

I think Fort has identified the right gap in the market. The intersection of longevity awareness and strength training growth creates strong demand for exactly this product. The automatic tracking is the critical feature. If it works reliably, Fort becomes the default wearable for anyone serious about strength training. If the exercise recognition is inconsistent, users will go back to manual logging and their existing wearables.
