Best AI workout apps for lifting (2026), picked by the job
“AI workout app” covers three different jobs: writing today's workout, moving your targets from what you logged, or changing the session while you're in it. Pick the app that does your job.

Short answer
It depends on the job. To have each workout written around the kit you have today, start with Fitbod. For a structured hypertrophy plan whose targets move from your logged sets, Alpha Progression. To run a coach-written program, Boostcamp; for a cheap log with optional AI planning, Hevy. Powerlifters training for a meet should look at JuggernautAI, and if you need a human, Caliber. Handler, our own app, is built for changes mid-session: Effort Check, busy-equipment swaps, Quick Gym and coach calls.

Who each app is best for, how it changes your targets, and what it costs.US list prices, checked October 30, 2026, each linked to the page it came from.
Best for writing today's workout around your equipment: Fitbod
Fitbod writes each workout for you from the equipment you have, your recent training and which muscles have recovered. That suits lifters who move between a home gym, a hotel and a commercial gym. If a station is taken, swipe left on the exercise and tap Replace. Its help pages say you can generate, log and save workouts offline and sync later. After the 7-day trial you need a subscription to log new workouts. You can repeat Saved Workouts and update their loads; Fitbod does not currently provide a built-in weekly planner.
US price: $15.99/month or $95.99/year, 7-day trial

Best for a structured plan with targets that move: Alpha Progression
Alpha Progression builds a structured plan, often for muscle gain, and its Pro recommendations suggest weight and reps for each set from your past workouts, the sets you've done today and an optional reps-in-reserve rating. The first time you do an exercise there's no recommendation yet. Swap an exercise and you choose whether the change is for today only or for the plan going forward. The logger and your own plans are free. The trade-off: there's no coach to talk to, and the recommendations want a few sessions of history first.
US price: Pro $12.99/month or $79.99/year; 14-day trial on yearly

Best for running a coach-written program: Boostcamp
Boostcamp is a library of coach-designed and community programs you can follow and log for free, with a tracker and a custom program builder. Pro adds Auto Progression, which works out your next numbers, and its 7-day trial is on the annual plan only. The free Swap Exercise lets you change a movement for one workout or for future weeks. Boostcamp says it has no Apple Watch or Wear OS app. The trade-off: the program does the thinking, so read the weekly schedule and equipment list before you start one.
US price: Pro $14.99/month or $59.99/year; 7-day trial on annual

Best cheap log with optional AI planning: Hevy
Hevy is a logbook first: build routines, log sets and see last week's numbers, free, with a cap on how many routines you can save. Hevy Pro adds Trainer, which builds a program from your goals, equipment, schedule and experience and adjusts your working weights from your performance. Pro is a fraction of what the workout generators cost. The trade-off: Trainer is a planner, not a coach you talk to, and the free version's routine cap is low if you run several splits.
Best when what you need is a human coach: Caliber
Caliber's tracker is free, with unlimited workouts. Caliber Plus adds coach-designed plans, and one-to-one coaching with a human is a separate monthly service whose price Caliber doesn't list publicly. Its connector lets ChatGPT or Claude read your training data, and it works on a free account. Pick Caliber when what you're missing is a person checking in, not an algorithm. The trade-off: human coaching costs far more than any app here.
US price: Plus $12/month or $72/year; coaching priced separately
Best for powerlifting meet prep: JuggernautAI
JuggernautAI is built for powerlifting: the squat, bench press and deadlift. You check in on your sleep, nutrition, strength and recovery, and it adjusts your training from there. It runs on iOS and Android, and new users get a two-week trial. The $349.99 yearly plan is on its own site; the US App Store lists the monthly plan. The trade-off: it's specialist and expensive, more than most gym-goers need if they aren't training for a meet.

Where Handler fits
Handler is our app, so it isn't in the picks above. It helps you change today's session. After your second working set, Effort Check asks how it felt and suggests a new target for the sets you have left. If the rack is taken, mark it busy. At a saved location, Handler swaps exercises you haven't started for ones with the same movement pattern (busy-equipment swaps). Quick Gym gives you 7, 10 or 15 minutes, and you can call your coach in a Chill, Hype, Direct or Savage style (coach styles and calls).
Price: $79.99/year, 7-day trial on iOS for eligible new subscribers; monthly price in the app. Limits: no free version, and it can't see the gym floor. Fitbod has an Apple Watch app. Handler doesn't yet. Offline logging hasn't been independently tested; coach chat and calls need a connection.
Checked against the app's code on October 29, 2026; not a multi-week test.
Next set, next workout, or a new workout?
“AI” covers three different jobs. A generator like Fitbod writes a fresh session each time from your equipment and recovery. A progression engine, like Hevy's Trainer, moves your targets from what you logged. A few apps act inside the session: Alpha Progression Pro can change the next set from the sets you've just done, and Handler's Effort Check suggests a new target for the sets you have left after the second working set. Work out which of those you actually need before paying for any of them. Most lifters only need one.
How we picked
We started from the job a lifter needs done, then picked the app whose own documentation shows it does that job. We didn't run a multi-week test of any app, ours included, and nothing here is scored. Prices are US list prices read on October 30, 2026 from each app's pricing or help page or its US App Store listing; your store may show a different price or offer.
Handler is our own product, available on iOS and Android. Pro is required after onboarding. We describe it in its own section, without a rating, and keep it out of the picks.
