EntrenAI or Fitbod: a gym-only AI or a plan for every sport?
Fitbod builds each gym session around the equipment you have and the muscles you've already worked, and it does that very well. EntrenAI generates a periodized plan for 12 sports, from hypertrophy and powerlifting to running, cycling, triathlon and HYROX. Here is an honest look at what each one does better.
Updated
Fitbod is a gym-only AI workout app from San Francisco that has been around since 2015. Tell it what equipment you have access to and it generates your next session, weighting the exercises towards the muscles that have had time to recover and away from the ones you trained yesterday. Its library of more than 1,000 exercises with demo videos is one of the largest in the category. If all your training happens in the gym, it is a very good specialist.
EntrenAI is an AI training plan generator for iOS and Android that covers 12 sports: hypertrophy, general strength, powerlifting, running, cycling, swimming, triathlon, duathlon, HYROX, hybrid training, speed and power, and public-service entrance tests. Instead of a fresh workout each day, it builds a periodized plan from a questionnaire about your goal, level, available days, equipment and injuries, then adjusts it as you go. A daily check-in on sleep, stress and fatigue feeds a Readiness Score that raises or lowers the load, RPE and RIR feedback tunes the weights, and a missed session gets redistributed across the week rather than deleted. You log sets, reps and loads inside the app and get weekly volume, personal records and race-time predictions back.
The honest summary is that Fitbod goes deeper into the gym, with a bigger exercise library and better videos, while EntrenAI goes wider, with structured blocks for sports Fitbod doesn't touch. If you only lift, Fitbod is a strong pick. If you lift and also run, ride, swim or train for HYROX, EntrenAI keeps all of it in one plan.
EntrenAI vs Fitbod: side-by-side
No marketing fluff, no half-truths. Here’s what each app actually offers.
| Feature | EntrenAI | Fitbod |
|---|---|---|
| Gym training: hypertrophy and strength | Yes: hypertrophy, general strength and powerlifting plans, periodized in blocks | Excellent, it is the whole point of the app |
| Running with periodization | Yes: periodized plans from a first 5K to the marathon, with race-time predictions | No |
| Cycling with FTP-based training | Yes: FTP-based intervals, road and indoor plans | No |
| Swimming, triathlon, duathlon and HYROX | Yes | No |
| Adapts each session to your recovery | Yes: a daily check-in on sleep, stress and fatigue sets a Readiness Score, RPE and RIR feedback adjusts the loads, and a missed session is redistributed across the week | Excellent: it tracks which muscles you have worked recently and builds the next workout around what has recovered |
| Adapts to your equipment | Yes: the questionnaire asks what you have, and exercises are swapped for the equipment available or for a niggle | Excellent: tick what is in your gym and every workout is built from it |
| Exercise variety | A smaller, curated library built around the main lifts, plus intervals and cardio sessions | More than 1,000 exercises at the time of writing |
| Demo videos | Video or animation for the main exercises; the library is smaller than a gym-only app's | Yes, every exercise comes with a video and an animation |
| Price | €7.99/month or €23.99/year, with a 7-day free trial | $12.99/month or $79.99/year at the time of writing Neither app has a permanent free plan; EntrenAI's trial lasts 7 days. |

Who should pick which app?
EntrenAI is for you if your week mixes disciplines: the lifter who also runs, the triathlete who needs strength work, the HYROX athlete juggling running and stations, or anyone who wants a plan with a beginning, a peak and a deload rather than a new workout every day. It also suits people who want their sessions to bend around bad sleep or a skipped day without starting over.
Fitbod is for you if the gym is your only sport and you value variety above structure. Its equipment-aware generator and huge video library make it a comfortable choice for someone walking into an unfamiliar gym, or for a beginner who wants to see every movement demonstrated before trying it.
Use both if you want Fitbod's exercise depth on lifting days and EntrenAI's endurance plans the rest of the week. It works, but most people find one app is simpler, so pick the one that matches your main sport.
Frequently asked questions
For pure hypertrophy in the gym, Fitbod is the more specialized tool. It has far more exercises, a video for each one and an interface designed around lifting and nothing else. EntrenAI covers hypertrophy well, with periodized blocks and load adjustments from your RPE and RIR, but its exercise library is smaller and it is not built exclusively for the gym. If you only lift, Fitbod is a fair choice; if you lift and train other sports, EntrenAI keeps it all in one plan.
EntrenAI is cheaper on both plans. It costs €7.99/month or €23.99/year, which works out at around €2 a month if you pay annually, and there is a 7-day free trial. Fitbod, at the time of writing, is $12.99/month or $79.99/year, roughly €12 and €75 respectively. Neither app offers a permanent free tier.
No. Fitbod is entirely focused on gym training, so it has no running, cycling, swimming or triathlon plans. If you want to run or ride with structure, you would need a second app for that side of your training, or a single app like EntrenAI that plans the gym and the endurance sessions together and syncs with Strava, Garmin, Apple Health and Health Connect.
Yes, and by a wide margin. Fitbod's library of more than 1,000 exercises with demo videos is one of its biggest strengths. EntrenAI's library is smaller and deliberately curated around the compound lifts that drive most of the progress, with video or animation for the main movements. If you get bored easily or want to see every variation demonstrated, Fitbod wins this one.
You can, if you want the best specialist for each side. Some people use Fitbod for their lifting days and EntrenAI for running, cycling or HYROX, which adds up to around €20 a month at the time of writing. The downside is that neither app sees the other's sessions, so your gym fatigue will not show up in your endurance plan. Most people end up choosing one app based on their main sport.
Both work, but for slightly different beginners. Fitbod is a little friendlier if you have never set foot in a gym, because every exercise has a video and the app tells you exactly what to do next with the equipment in front of you. EntrenAI is the better choice if you want a proper progression from day one, with a plan that builds in blocks and adjusts to how you are recovering, or if you expect to add running or another sport later.
