FitnessAI vs Fitbod
Published November 12, 2026
Fitbod is the deeper of the two, building each workout around which muscles have recovered, with 1,000+ exercises on multi-angle video, for $95.99 a year; FitnessAI does the core job of setting sets, reps and weight every workout, with yearly plans of $59.99 to $89.99. If you want the weights set for you without paying either, RIRLift does it free on a plan you pick, from every set you log, on iPhone and Apple Watch.

What separates FitnessAI and Fitbod
-
Both set the numbers
Each picks the exercises and sets the sets, reps and weight for you. FitnessAI's algorithm is built on 5.9 million workouts; Fitbod's draws on its own users' logged workouts.
-
Recovery is Fitbod's edge
Fitbod scores every muscle 0–100% and builds around the freshest ones, counting runs, rides and swims from Apple Health. FitnessAI sets progressive overload from your logged workouts.
-
Price depends on the plan you land on
Fitbod is $15.99/month or $95.99/year after a 7-day trial. FitnessAI's plans run $9.99 to $14.99 a month or $59.99 to $89.99 a year, and its Body Scan is sold separately.

Where RIRLift is different
RIRLift doesn't write a new session each day. You keep a plan, and every set's weight comes from the one before it, free. Tap any weight to see why.
Fitbod, FitnessAI or RIRLift in a real week
A week at a hotel gym
You're traveling for work. The hotel has dumbbells to 50 lb, a cable stack and a Smith machine.
| App | What it does here | For this lifter |
|---|---|---|
| Fitbod | Change your equipment in its settings and it builds the week's sessions from what's there. | The smoothest fit for a gym that changes. |
| FitnessAI | Plans around whatever equipment you have available. | Fits too, for less. |
| RIRLift | Keeps your plan and swaps lifts for ones your equipment list allows. A swapped lift starts at a weight worked out from the one it replaced. | Fits if you want your usual plan, adjusted. |
For travel, all three work. The difference is whether your plan comes with you.
Leg day after a short night
You slept five hours and the first set on the Smith machine fell short. You log what actually happened.
| Exercise | You logged | Next session | Why |
|---|---|---|---|
| Smith Squat | Set 1: 225 lb × 7, 2 left | Set 2: 220 lb × 8 | 7 reps is below the 8–12 range, with 2 left as planned. 9 reps to failure against a planned 10, so 225 × 38 ÷ 39 ≈ 219 lb, loaded as 220 lb. |
| Heels-Elevated Goblet Squat | 50 lb, 12 / 12 / 12 reps, 2 left | 55 lb × 8 | Every set at the top of 8–12: one 5 lb step, reps back to 8. |
The bad set changed the next one, not next week's plan.

Ask Coach for the plan
Tell Coach your days, goal and equipment, the way you'd onboard in FitnessAI or Fitbod. Review the plan before it applies.
-
Keep your equipment list current
Exercises and swaps stay inside what's on it, at home or on the road.

Log the bad days honestly
The next set adjusts to what you did, so a rough set costs you one lighter set, not a week.
