Gymex vs Fitbod: Which Wins in 2026?
Fitbod and Gymex both help you train — but they solve different problems. Fitbod is an AI session generator; Gymex is a full AI strength coach. Here's an honest head-to-head on programming, coaching, price and who each one is really for.
The short answer
Fitbod is the closest software rival, but it improvises sessions where Gymex programs blocks — and Gymex is cheaper with a real free tier. If you want an app that decides what today's workout looks like, both do it. If you want an app that decides what the next eight weeks look like, adapts them to your recovery and performance, and then tracks the food that fuels them, only Gymex does that.
What is Fitbod?
Fitbod builds each workout from your training history and recovery, adjusting volume by muscle group — the most hands-off of the mainstream logging apps. Its biggest strength is genuinely useful daily session generation that removes "what should I do today?". Tell it your equipment, your training goal and how long you have, and it assembles a workout, weighting muscles it judges to be recovered and backing off ones you hit hard recently. It has been doing this for years, it works on iOS and Android, and for a lot of general gym-goers it is the app that finally made training consistent.
What Fitbod deliberately doesn't do is look further ahead than the next session. There is no multi-week plan with a target, no deload week on the calendar, and no coaching layer you can talk to. Each workout is good in isolation; whether the string of them adds up to progression is largely left to you.

Who each app is really for
Fitbod is for the lifter who has no interest in planning. You train three to five times a week, you want to walk into the gym and be told what to do, and you're happy for that decision to be made fresh every morning. If you've never followed a periodised program and don't feel the lack of one, Fitbod's improvisation is a feature, not a gap. Both apps run on iOS and Android, so platform no longer forces the decision either way.
Gymex is for the lifter who has started asking harder questions: why has my bench stalled, should I deload, am I eating enough to support this block? It suits people who want the convenience of generated sessions and the confidence that those sessions are stepping stones toward a defined goal — with a coach they can interrogate when something feels off. If you've outgrown "here's a workout" and want "here's the plan, and here's why", that's the switch. For the wider field, see our roundup of the best AI workout apps in 2026.
Pricing breakdown
Fitbod costs roughly £10/month after a short free trial — a handful of generated workouts before the paywall. Paid monthly, that's about £120 a year, and there is no ongoing free tier to fall back on if you cancel.
Gymex starts free — a genuine free tier, not a countdown — and paid plans run Core at £7.50/month, Premium at £15/month and Pro Premium at £20/month, with 17% off when you pay annually. The maths on the most directly comparable plan:
| Plan | Monthly | Cost per year (paid monthly) | Annual price (17% off) | Effective monthly |
|---|---|---|---|---|
| Fitbod | ~£10 | ~£120 | — | ~£10 |
| Gymex Free | £0 | £0 | £0 | £0 |
| Gymex Core | £7.50 | £90 | £74.70 | ~£6.23 |
| Gymex Premium | £15 | £180 | £149.40 | ~£12.45 |
| Gymex Pro Premium | £20 | £240 | £199.20 | ~£16.60 |
So even before features enter the picture, Gymex Core undercuts Fitbod by roughly £30 a year paid monthly — or about £45 a year on the annual plan — while including nutrition tracking Fitbod simply doesn't have.

Feature depth: beyond the table
Periodised mesocycles vs per-session generation
This is the core philosophical difference. Fitbod's engine answers one question repeatedly: given what you've done, what's a good session today? It does that well — exercise selection, sensible set and rep schemes, recovery-aware muscle rotation. But no session knows about next week's, because next week hasn't been planned. Progress happens, but as a side effect.
Gymex writes a full mesocycle: a multi-week block with a stated goal, planned progression and a deload built in. Today's session exists because of where it sits in that block — week three of an accumulation phase is deliberately different from week one. The block then adapts weekly from what you actually logged, so the plan is structured and responsive rather than one or the other.
What RIR-based autoregulation means in practice
Reps in reserve — how many reps you had left in the tank — is the signal good human coaches watch and most apps ignore. Gymex infers RIR from your set history and uses it to set your next weights: hit your reps with more in reserve than expected and the load climbs; grind out a set at zero RIR and the app backs off before you stall or dig a recovery hole. Fitbod estimates weights from history too, but without an RIR model it can't tell the difference between a set that was easy and a set that nearly broke you — and that difference is where progress lives. It's also how Gymex spots a genuine plateau rather than one bad day.
Voice logging: the workflow difference
Both apps only learn from what you log, so logging friction matters more than any feature list. Fitbod uses conventional tap-based logging. In Gymex you say "bench, 80 kilos, 8 reps, 2 in the tank" between sets and the set — RIR included — is logged. That sounds like a small thing until you realise the RIR data powering the autoregulation above exists because saying it out loud is easier than thumbing a picker with chalky hands. And when something does feel wrong, you can ask the coach directly — "why did my squat drop this week?" — and get an answer grounded in your own logs. Fitbod has no equivalent conversation to have.
Where Fitbod wins
Honesty first: there are real reasons to pick Fitbod.
- Daily improvisation. Fitbod is excellent at improvising a sensible single session on the fly, especially for general gym-goers. If your schedule and equipment change constantly and you want a good workout with zero planning, its per-session engine is arguably the best in the category.
- Muscle-recovery balancing. Fitbod's per-muscle recovery model — rotating volume away from recently worked muscle groups — is mature, visible and genuinely useful for avoiding accidental overlap between sessions.
- Exercise media library. Fitbod's decade of development shows in its large, polished exercise database with demonstration animations. Gymex covers the major lifts and now runs on both iOS and Android too, but Fitbod's media library is still broader for obscure variations.
- Track record. Fitbod has been refining its recommendations for years and has a large, established user base. Gymex is the newer app — currently rated 4.9 from its early App Store ratings — so if a long public history matters to you, that's a point to Fitbod.
Where Gymex wins
Fitbod suggests one session at a time; it does not write a periodised block with a goal and deload, coach you conversationally, log by voice or track nutrition. Gymex does all four. That's the difference between an app that records or suggests training and one that actually programs and autoregulates it for you — for a fraction of the price of a human coach.
On top of programming, Gymex folds in the things that usually mean paying for a second or third app: macro and meal planning with barcode and photo meal scanning, body metrics and progress photos, plateau and PR detection, and a social feed. Training, recovery and food finally live in one place, which is what makes the coaching coherent — the app that plans your hypertrophy block also knows whether you ate enough protein to support it.

Moving from Fitbod to Gymex: what transfers, what doesn't
What transfers: your training knowledge and habits. The exercises you favour, the split rhythm you're used to, the equipment you have — all of that carries straight over when you tell Gymex your setup, and the coach will build your first block around it. Your understanding of your own numbers transfers too: you know roughly what you bench and squat, and that's enough for Gymex to calibrate starting loads.
What doesn't: your logged history. There's no import of your Fitbod workout archive, so Gymex starts without your years of session data. In practice the cost is smaller than it sounds — because Gymex autoregulates from RIR rather than replaying old numbers, it typically recalibrates to your current strength within the first couple of weeks of logged sessions. But if your Fitbod history itself is precious to you, export or screenshot anything you want to keep before you cancel.
The sensible path: download Gymex on the free tier, run it alongside Fitbod for a week or two, and let the first generated block make the case. Most switchers tell us the moment it clicks is the first deload that arrives on schedule — the thing Fitbod never planned for them.
Bottom line: Fitbod is the closest software rival, but it improvises sessions where Gymex programs blocks — and Gymex is cheaper with a real free tier. If you're weighing up more options, read our Fitbod alternatives roundup, or try Gymex free on iOS and decide for yourself.
Frequently asked questions
Is Gymex better than Fitbod?
Fitbod is the closest mainstream rival: it genuinely solves the daily question of what to train by building each session from your history and recovery. Gymex thinks longer-term — it writes a periodised block with a goal and deloads, coaches you conversationally and tracks nutrition. Fitbod improvises days; Gymex plans months.
Is Fitbod or Gymex cheaper?
Fitbod is roughly £10/month with only a trial free — about £120 a year. Gymex has a genuine free tier, and paid plans start at £7.50/month, dropping to roughly £6.23/month on an annual Core plan (17% off). Gymex is both cheaper to start and broader in scope.
Can Gymex replace Fitbod?
For most gym-goers, yes. Gymex generates your sessions too, but within a structured multi-week block that progresses toward a goal — then it reads your RIR, detects plateaus, logs by voice and tracks nutrition. Keep Fitbod only if you actively prefer unplanned, day-by-day variety.
What does Gymex do that Fitbod doesn't?
Fitbod suggests one workout at a time and does not build a periodised block, hold a coaching conversation, log by voice or track nutrition. Gymex does all four, so your daily sessions add up to a plan rather than a string of improvisations.
Is Fitbod actually AI?
Yes, in a real but narrow sense. Fitbod uses a machine-learning recommendation engine that picks exercises, sets and reps for your next session based on your logged history, available equipment and per-muscle recovery state. What it does not do is hold a conversation, reason about a long-term goal or autoregulate from reps in reserve — so it is better described as an AI session generator than an AI coach.
Is Fitbod worth the money?
If all you want is a sensible generated workout each day and you will use it several times a week, roughly £10/month is defensible — it is far cheaper than a personal trainer. The value case weakens if you also pay separately for a nutrition app or want periodised programming, neither of which Fitbod includes. Gymex covers training and nutrition in one subscription from £7.50/month, with a free tier to test first.
Does Gymex work on Android?
Yes. Gymex now runs on Android (via Google Play) as well as iPhone, iPad and Apple Watch — the same features, pricing and account sync on each. Fitbod is also on both platforms, so platform is no longer the deciding factor; choose on coaching depth instead. You can try Gymex free on either platform and compare directly.
