This high visual quality, coupled with minimal buffering, results in highly immersive fitness experiences.

Additionally, 5G enables Multiplayer VR fitness gaming where groups can participate together in fast-paced VR workouts or training games. Zwift, a popular indoor cycling app, now supports 50 players together in a 5G-powered virtual world. Such interactive experiences will become more mainstream as 5G coverage rises globally.


  • Uninterrupted Tracking for Outdoor Fitness

For outdoor activities like running or cycling, 5G allows fitness apps to provide constant biometric tracking and mapping without any drop-offs in connectivity. As users move through different areas, their workout data can be continuously uploaded to the cloud rather than having intermittent gaps.

Apps like NURVV Run leverage 5G to offer uninterrupted foot strike analysis and running coaching in real-time. This leads to outdoor fitness experiences where users feel seamlessly connected throughout.

As more gyms, stadiums, trails, parks and cities become 5G enabled over the next few years, it will expand the possibilities for creating fitness experiences powered by real-time data.

Wearable Devices for 24/7 Fitness Tracking

Wearable devices have become massively popular for continuous fitness tracking as well as receiving real-time guidance during workouts. According to IDC, shipments of wearable bands and watches will cross 160 million units globally. By seamlessly incorporating wearable tech, fitness apps can tap into a constant stream of biometric data and provide personalized recommendations.


  • Enhanced Tracking with Advanced Sensors 

Next-generation wearables are equipped with sophisticated sensors to capture comprehensive data on the wearer’s exercise performance, recovery, sleep, and overall health 24/7.

For example, the WHOOP 4.0 band uses 5 LEDs for accurate heart rate measurement, an accelerometer, a gyroscope, and a SpO2 sensor to track advanced strain, sleep, and recovery metrics. Deriving such granular data allows fitness apps to offer tailored insights and feedback to the user.

Wearables with electromyography (EMG) sensors, like the Myontec Mbody shorts, can track muscle contractions and exercise intensity. This enables apps to identify imbalances or optimize hypertrophy and strength programs based on an individual’s biomechanics.

  • Personalized Guidance through Wearable Integration

Leading apps like Apple Fitness+, Peloton, Nike Run Club, and MyFitnessPal seamlessly sync up data from wearables to offer customized fitness experiences. 

Wearable integration allows these apps to:

- Provide real-time metrics like heart rate and pacing without needing to glance at the wearable device

- Retain workout data like GPS maps, totals stats, and rep counts within the app for post-workout review 

- Offer tailored workout recommendations and training plans based on the user’s fitness patterns and recovery needs observed through the wearable 

- Provide form correction, technique analysis, and safety alerts based on real-time data like unstable heart rate or dangerous exercise form


As wearables become mainstream, they will be integral to fitness apps, creating personalized experiences driven by users' own quantified biometrics data.

AI and Machine Learning for Adaptive Training 

Sophisticated AI is enabling fitness apps to act as smart virtual coaches that customize guidance to each user and adapt plans based on changing fitness levels and goals.

  • Workout Personalization through ML Recommendation Engines

Machine Learning algorithms analyze users’ performance, feedback, goals, and other engagement data to build a fitness app recommendation engine. These engines suggest tailored workout routines, training plans, gear, playlists, challenges and other features personalized for each user.

As apps gather more data over time, their ML models improve, and the level of customization increases. AI can even design entirely new workouts optimized for a user’s needs instead of recommending pre-defined programs.


  • Intelligent Form Tracking and Correction

Computer vision techniques like pose estimation allow apps to track exercise form and provide real-time corrections before injury-causing mistakes become habits.

For example, the Paofit app uses AI to analyze exercise repetitions in bodyweight workouts and detect suboptimal techniques. Users get tailored cues like “straighten knees” to improve form.

Startups like Forsight use sensor fusion and deep learning on thermal video data to accurately track movement patterns across both sides of the body during rehab exercises. Such intelligent form tracking will be critical to prevent injuries as fitness application development becomes virtual personal trainers.

  • Motivation through Personalized Insights

Leveraging data from wearables and external apps via APIs, fitness platforms can gain a holistic context of users’ health metrics, sleep patterns, nutrition, and more.


AI can then derive personalized insights to nudge users and keep them motivated. 

For example, the fitness social network Strava analyzes runners’ training load and race performances to provide customized training recommendations and predict potential race finish times.

As privacy concerns are tackled, the combinatorial power of cross-app data will allow fitness platforms to offer hyper-personalized guidance based on the complete understanding of each user's body, lifestyle, and goals.
