17 Best Online Fitness Programs and Workout Apps in 2026 Tried & Tested

Consider these picks the ones we will never delete (even if we are running low on storage!). AI fitness apps with adaptive workout planning adjust your workout based on how you’re doing. For example, if you were feeling tired yesterday and did a lighter workout, the app might ease up today—or, if you crushed it, it might challenge you a bit more. Over time, these apps “learn” from your progress and make real-time changes to your routines. This keeps you motivated and makes sure you’re always pushing just enough to lose weight and make progress, without burning out.

Best workout app for running

Like running on a treadmill, indoor training isn’t always the most fun. I will say, though, that Zwift does a great job of bringing outdoor rides into your home thanks to its video-game-style design. Bojana found the initial setup to be very easy, rating it 5 out of 5 stars, though you’ll need your own indoor trainer, which may take a little longer to setup if you don’t already own one. Zwift uses game features to make indoor cycling and running more fun, but the app has a history of crashing and isn’t great on small phone screens. Future is an outstanding app in nearly every category, but the only real drawback is the cost, as it’s certainly not cheap. It should be noted that customer reviews are mixed, with some reviews even calling BetterMe a scam.

FlexFit adapts to your equipment, your time, and your goals — not the other way around. However, the partnership didn’t last and the workouts were removed from Netflix in March 2024, according to What’s on Netflix. The Netflix and Nike deal was meant to see if Netflix could compete with Peloton for streaming workouts, but it seems the company didn’t want to progress any further. There are also handy features like Strava Beacon, which are designed to keep you safe, by allowing your friends or family members to track your live location on a run.

Privacy & Data

The guided fitness programs app’s AI tracks your progress over time, providing you with new suggestions for weights and reps to maximize muscle growth once it sees that you can handle certain workouts. If you can’t complete a set with a certain weight, the AI might even create a plateau breaker exercise – such as an exercise with lighter weights or fewer reps – to help you stay on track. This program is based on a hybrid workout approach, involving three sessions for strength training and two for cardio per week. It will also have a stretching session on resistance training days after the workout.

The programming on a macro-level may not be adequate for intermediate or advanced exercisers, and it only earns 3 out of 5 stars for the category. JuggernautAI costs slightly more than the average app, thought it offers a longer trial period than most so new users can experience the programming. Although more equipment is needed than in other apps we reviewed, Amanda still gives JuggernautAI a 4-out-of-5-star rating for equipment demands. “You can swap in exercises each day or for an entire block based on what you have handy,” she explains. Because this is a powerlifting program, it may not be a surprise that you’ll need a squat rack, bench, barbell, and weight plates to complete your workouts.
