The workout app market generates billions of dollars annually by convincing people that the right software will make them more consistent. Most of the apps in that market are marginally useful at best. The genuinely good ones are mostly free.
Here is what the free options provide, where the paid options actually earn their price, and which apps are worth installing.
What a Good Workout App Actually Does#
Before assessing specific apps, it helps to be clear about what you need:
Structure. A workout with a clear sequence of exercises, sets, reps, and rest periods. This removes decision fatigue mid-session and keeps you focused on training rather than planning.
Progression. A way to track what you did last session so you know what to do next. Without this, you are exercising rather than training.
Demonstration. Clear video or image guidance on how to perform each movement correctly. This matters most for beginners learning new exercises.
Most apps provide some version of the first two. Fewer do all three well. The apps worth using are the ones that remove friction from training rather than adding it.
The Best Free Options#
Nike Training Club#
Nike Training Club is the best free workout app available and it is not particularly close. It provides hundreds of structured workouts across strength, cardio, yoga, and mobility, with video guidance for every exercise. Workouts are organized by duration (15 to 60 minutes), difficulty level, and equipment availability.
The training plans are thoughtfully designed and genuinely progress over weeks rather than repeating the same sessions. The app is fully free with no meaningful features behind a paywall.
The caveat: NTC works best as a guided workout selector rather than a progressive strength programming tool. It is excellent for conditioning and variety, less ideal if your specific goal is getting stronger in a small number of movements.
YouTube#
YouTube is not technically an app in the traditional sense, but it is the most comprehensive free fitness resource available. The FitnessBlender channel alone has over 600 free full-length workouts, organized by duration, intensity, and equipment. Chloe Ting, MommaStrong, Jeff Nippard, Alan Thrall, and dozens of other creators offer high-quality programming at zero cost.
The limitation is search and organization. Finding a specific workout requires more manual navigation than a structured app, and tracking your history requires a separate system. But the depth of content is unmatched.
If you know what kind of training you want and do not need a tracking system, YouTube is the answer.
Strong (Free Tier)#
Strong is a workout logging app rather than a programming app. You build your own workouts, log sets and reps in real time, and the app tracks your history and calculates volume over time. The free tier allows up to three workout templates and provides basic history.
For anyone doing their own programming or following a written plan, Strong solves the tracking problem effectively. The paid tier adds unlimited templates and more detailed analytics. The free tier is sufficient for most people.
StrongLifts 5x5#
StrongLifts 5x5 is a single-purpose app for the 5x5 barbell program (three alternating workouts: squat, bench press, overhead press, deadlift, barbell row). If you are doing barbell training, this app handles all the programming and progression automatically. It is free with an optional paid upgrade for advanced features.
The free tier is entirely functional for running the program.
When Paid Apps Make Sense#
Paid workout apps make sense in specific circumstances. They do not make sense as a default.
If You Need Highly Structured Progression for a Specific Goal#
Apps like Madbarz (calisthenics progression), RP Hypertrophy (bodybuilding programming), or Ladder (team-based strength coaching) provide structured, periodized programming that free apps do not match. If you are pursuing a specific performance goal and find that free programming leaves you uncertain about what to do each session, a paid app that answers that question is worth evaluating.
The test: try the free tier or trial period seriously for two to four weeks. If the structure genuinely improves your training, the subscription has earned its keep.
If Accountability Is the Missing Variable#
Some people need the social or gamification element of a paid app to stay consistent. If you have repeatedly tried free resources and not stuck with them, and you have reason to believe the paid features of a specific app would change your behavior, that is a reasonable investment.
Be honest about whether you have actually used the free options consistently before concluding that a paid version would solve the problem.
What to Skip#
Apps that lock basic features behind a paywall immediately. If you cannot log a workout or follow a basic plan without paying, move on. Enough quality free alternatives exist that this business model should not be rewarded.
Calorie-burn estimates. Every app and wearable that claims to tell you exactly how many calories you burned during a workout is providing a rough guess. The formulas used are based on population averages with high individual variance. Use calorie estimates as directional information, not precise data.
Subscription apps with no trial. Any reputable fitness app offers a free trial. Skip apps that require payment before you can evaluate whether the product works for you.
The Simple Stack#
For most people doing bodyweight or light-equipment training:
- Nike Training Club for structured workout sessions and variety
- Strong (free tier) for logging your own sessions and tracking progress over time
- YouTube for exercise demonstrations and supplemental content
These three together cost nothing and cover everything a recreational fitness goal requires.
Do this today: Download Nike Training Club and complete one workout. Pick a 20 to 30 minute session at your current level. That is the whole trial. If you finish it and the format works for you, you have a free training resource that will not ask you to upgrade.
