U.S. Fitness Apps Market Size, Share

Market Size & Trends

The U.S. fitness apps market size was estimated at USD 4.23 billion in 2024 and is projected to reach USD 10.10 billion by 2033, growing at a CAGR of 10.0% from 2025 to 2033. The growth is attributed to the evolving consumer health priorities and technological advancements. Rising health awareness and a growing focus on preventive healthcare have led individuals to actively seek tools for managing fitness and well-being. This shift is further supported by the widespread adoption of smartphones and improved internet accessibility, making fitness apps easily available and convenient to use. In addition, the increasing usage of wearable devices such as smartwatches and fitness bands enables real-time health tracking and enhances user engagement. Moreover, the shift toward at-home workouts and virtual coaching, especially following the COVID-19 pandemic, as consumers continue to prefer flexible, on-demand fitness solutions over traditional gym routines. 

Rising Adoption of Fitness Apps in the U.S.: A Growing Trend

Growing awareness around physical fitness and preventive healthcare has significantly boosted the adoption of fitness apps in the U.S. Consumers are increasingly turning to digital platforms to monitor their health, manage weight, reduce stress, and maintain an active lifestyle. With rising concerns about chronic conditions such as obesity, diabetes, and cardiovascular diseases, many individuals are proactively using fitness apps to track exercise routines, diet plans, and overall wellness.

Rising Obesity Rates in the Country

This shift is particularly urgent given the rising obesity rates in the country. According to the CDC, in 2022, 22 U.S. states reported adult obesity rates above 35%, underscoring the critical need for accessible and effective health management tools.

Some stats related to Obesity

• Obesity prevalence was slightly higher in men (43.0%) than women (41.9%), but severe obesity was more common in women (11.5%) than men (6.9%).

• More than 2 in 5 adults have obesity, and the prevalence has increased from 30.5% in 1999-2000 to 41.9% by 2017-2020.

• Recent data from 2021-2023 shows the obesity rate among adults was about 40.3%, with severe obesity at 9.4%.

• Nearly 3 in 4 U.S. adults are now considered overweight or have obesity, indicating a combined high prevalence of these conditions.

• The rise in obesity has been linked to lifestyle changes, increased sedentary behavior, larger portion sizes, and higher calorie intake from processed foods.

• Projections warn that without significant intervention, over 260 million people in the U.S., including more than half of children and adolescents, could be living with overweight or obesity by 2050.

Digital Access Driving Convenience

The widespread availability of smartphones and high-speed internet has created a favorable environment for fitness app adoption. With smartphones now an integral part of daily life, users can conveniently access fitness programs, track performance, and receive personalized feedback anytime, anywhere.

Responding to this demand for personalization and convenience, Peloton launched its standalone Strength+ app in the U.S. in December 2024, transitioning it from beta to full release. The app features personalized, multi-week gym-centric strength programs, a workout generator, audio coaching, progress tracking, and equipment tutorials-further expanding the capabilities and appeal of mobile fitness solutions.

The Role of Wearables in Enhancing Engagement

Wearable fitness devices such as Apple Watches, Fitbits, and Garmin trackers are also critical in driving app engagement. These devices provide real-time data on steps, heart rate, calories burned, and sleep patterns. Syncing with fitness apps enhances user insights, improves tracking accuracy, and enables more effective goal-setting.

Key Advantages:

• Device-Agnostic Architecture: Supports both consumer and medical-grade wearables, offering flexibility without vendor lock-in.

• Normalized Metrics: Converts diverse data formats into a consistent structure, easing analysis across devices.

• Real-Time Data Flow: Enables continuous live streaming during workouts for immediate feedback and adjustment.

• Reduced Development Overhead: Streamlines development by eliminating the need to manage multiple device SDKs through a single API endpoint.

Example:

A user starting a guided strength training session with a smartwatch benefits from Thryve’s real-time data streaming. If the user’s heart rate exceeds a threshold, the app recommends rest; if the intensity drops, it encourages increased effort. This dynamic feedback, based on physiological data, makes workouts safer, more engaging, and effective.

By providing real-time insights and reducing technical complexity, Thryve empowers fitness apps to offer truly personalized workout experiences responsive to individual user needs.

For instance, in response to this growing demand for deeper integration, Fitbit launched the Charge 6 fitness tracker in the U.S. in September 2023. It featured the company’s most accurate heart-rate sensor to date, Bluetooth gym-equipment connectivity, more than 40 exercise modes, on-wrist YouTube Music controls, and accessibility enhancements, demonstrating how hardware innovations are fueling the evolution of fitness apps.
