Hevy AI Coach: Where the Lift Log Ends and the Plan Begins

Hevy is one of the cleanest workout loggers ever built. Fast set entry, decent exercise library, good PR tracking, social feed if you want it. But Hevy is a logger. It does not write your program, it does not adjust when you sleep five hours, and it does not know you ran 12 km yesterday. This guide is for the lifter who's outgrown the spreadsheet-with-a-UI and wants an actual coach in the same app.

What Hevy Does Well

Credit where it's due: Hevy nailed the core lifting loop. Rest timer that doesn't get in the way. Set/rep/weight entry in two taps. Routine templates you can clone and tweak. Plate calculator. Body part charts. Decent CSV export. If your entire training life is "I follow a fixed program, I want to log it without friction, I want a graph of my squat over time," Hevy is enough.

The pricing reflects that scope. Hevy Pro sits around five bucks a month for unlimited routines, advanced analytics, and the AI features they've added recently. It's a lifting tracker that grew an AI feature. The AI sits on top of the log. The log is the product.

What Hevy Doesn't Do (And Won't, Without Becoming a Different App)

Hevy doesn't plan. You bring the program. Whether you wrote it, bought it, or copied a Reddit PDF, Hevy is the place you log it.

Hevy doesn't adapt. If you crush every set with two reps in reserve for four weeks, Hevy will not auto-bump the weight or restructure the block. If you miss reps three sessions running because you're under-slept, Hevy will not deload you. The progression is in your head, or it's in the program you bought.

Hevy doesn't read recovery. There's no HRV input, no sleep score, no readiness layer. Two sessions look identical in the log whether you slept eight hours or four. The bar weight on the page doesn't know about the rest of your physiology.

Hevy doesn't see the other sports. If you run, cycle, swim, climb, or do anything that isn't a barbell movement, Hevy is blind to it. Hybrid athletes and CrossFitters end up running Hevy plus Garmin plus a notes app plus a nutrition tracker, stitching the picture together by hand.

Hevy doesn't fuel you. No macro tracking, no meal log, no protein-target nudges around heavy sessions.

None of this is criticism. Hevy chose a lane and built the best version of it. It's just useful to be honest about what the lane is.

What an AI Coach Actually Needs to Do

The phrase "AI coach" gets thrown around a lot. A real one has to do four things that a logger plus a chatbot can't:

1. Write the plan. Not "suggest a workout." Build a week that respects your goal, your equipment, your other sports, your recovery, and your life. Then rewrite next week based on what happened in this one.
2. Read everything. Lifts, runs, sleep, HRV, body comp, nutrition, mood, soreness. Coaching decisions you make off only the lift log are coaching decisions made half-blind.
3. Adapt without being asked. If readiness tanks, the plan compresses. If volume tolerance grows, the plan expands. The athlete shouldn't have to file a ticket.
4. Explain itself. When the coach moves your back squat from Tuesday to Thursday, you should be able to ask why and get an answer that cites your data, not a horoscope.

Hevy's AI features answer chat questions about your log. They do not do steps one through three.

How Movement Rebels Runs the Whole Week Around the Bar

Movement Rebels is the most complete training app on the market, and strength is one of its five pillars, not a bolt-on. The strength logger handles hypertrophy, powerlifting, Olympic lifting, calisthenics, and strongman, with a full exercise codex and form videos on every movement. You can log a Hevy-style session inside MR with the same speed of entry. That's the floor, not the ceiling.

What sits on top of it is the part Hevy can't ship without becoming a different product:

The adaptive weekly plan. The coach writes your week. Your training age, your goal, your equipment, and the other sports you do all feed into it. If your priority is a 200 kg deadlift but you also run two times a week, the plan respects both, places the heavy pull when you're freshest, and protects the day after with mobility instead of another grinder.

The recovery read. Garmin native, Apple Health native through the iOS app (which is where WHOOP, Oura, Polar, and COROS data lands today), Strava native read and write. The coach sees HRV, resting heart rate, sleep duration, and yesterday's training load. If you slept five hours and your HRV is in the basement, the coach pulls the squat session to a technical day and reschedules the heavy work. You don't have to ask.

The cross-domain context. The coach reads your Rebel Fuel log and notices you've been 500 kcal under target during a hypertrophy block, and tells you to eat. It sees you logged a 90-minute Zone 2 ride yesterday and adjusts today's leg session accordingly. It pulls from a knowledge base that covers female cycle training, masters athletes, postpartum return, and sport-specific prep, so the advice you get isn't generic.

The recovery tools in the same app. Breathwork timer, NSDR for nap recovery, cold exposure, fasting timer, deadhang, HRV-guided readiness. Logged to one timeline next to your lifts and your runs.

The honest caveat. Movement Rebels does not have a social feed. No followers, no kudos, no leaderboards. If you love Hevy's feed for the dopamine, keep it. The MR↔Strava integration is read plus write, so your sessions still show up where your friends train.

Pricing

Free is a 7-day full-access trial. The whole app, the coach included. After that, Pro+ at $20 a month gets you 250 AI credits monthly and the full library. Hevy Pro costs roughly half that and does roughly an eighth of the job. Different products, different price points, different scopes.
