From couch to 5K: the growing popularity of fitness apps among Americans

In a post-pandemic America, fitness is no longer just about hitting the gym—it’s about hitting download. Fitness apps like Nike Training Club, Peloton, Fitbod, and Couch to 5K are experiencing a surge in popularity as Americans seek affordable, flexible, and personalized workout options.

According to the U.S. App Store analytics firm SensorTower, health and fitness app downloads rose by 17% in the first half of 2025, with over 52 million installs in the U.S. alone.

From calorie counting to HIIT, meditation to marathon training—fitness apps are turning phones into personal trainers. And Americans are loving it.

“Everything is on my phone now. I went from barely walking 2,000 steps to running 5Ks every weekend,” says Jessica Rowe, 34, from Austin, Texas, who used the Couch to 5K app for 8 weeks.

Features like AI-powered routines, real-time coaching, Apple Watch syncs, and even community leaderboards are making the virtual fitness space highly immersive.

Experts point to three key drivers:

• Convenience – No more commuting to a gym.
• Affordability – Most apps are free or under $10/month.
• Customization – Personalized workout plans that adapt over time.

With inflation pressuring household budgets, fitness apps are the go-to for Americans trying to stay healthy without breaking the bank.

These apps are doing more than building muscle—they're building habits. Apps like Headspace, Alo Moves, and Calm combine fitness with mental wellness, helping users de-stress, sleep better, and stay balanced.

"Fitness apps gave me structure when life felt chaotic," says college student Darion Martinez, 21, who uses FitOn daily. "I start my day with a 10-minute yoga session and feel grounded."

Whether it's virtual 5K races, AI fitness coaches, or interactive yoga classes, America’s fitness journey is now digital. With Gen Z and Millennials leading the charge, the fitness app economy is set to grow beyond $30 billion globally by 2026—with the U.S. driving the demand.
