Hevy tracks your sets and reps. Your AI coach tells you what they mean. Connect Hevy and get feedback after every gym session on what's working, what's stalling, and what to change.
Every exercise, set, rep, and weight you log in Hevy lands in your AI coach's context. Supersets, drop sets, rest-pause sets - all of it. Your complete strength training history is there for analysis.
The AI calculates estimated one-rep maxes using the Brzycki or Epley formula and tracks them over time. It detects when a lift has stalled and recommends specific changes - rep scheme adjustments, exercise variations, or a deload week.
Weekly volume load per muscle group is tracked automatically. A 2019 meta-analysis in the Journal of Sports Sciences found that 10+ weekly sets per muscle group drove more hypertrophy than fewer sets. The AI tells you which muscle groups are getting enough volume and which aren't.
Over time, the AI sees which exercises drive the most progress for you specifically. If your bench press stalls but your incline dumbbell press keeps climbing, it'll suggest rotating exercises to break through the plateau.
You need a Hevy Pro subscription for API access. Copy your API key from hevy.com/settings and paste it into your athletedata.health dashboard. After that, every workout you complete syncs automatically.
All logged exercises, sets, reps, weight used, and workout duration. From this it calculates estimated 1RMs, total volume load, muscle group frequency, and progressive overload trends across your full training history.
That's one of the main things it does. It monitors your estimated 1RM trends for all your lifts. When progress stalls for two or more weeks, it suggests evidence-based fixes: adjusting rep ranges, swapping exercises, cycling intensity, or timing a deload.
Yes. It categorizes every exercise by primary and secondary muscle groups and tallies weekly sets. If your chest is getting 18 sets per week but your rear delts are at 4, it'll point that out. It compares your numbers against research-backed benchmarks for hypertrophy.
Connect Strava too. The AI then sees your full training picture and factors in total stress. If you did heavy squats on Monday and want to run Tuesday, it accounts for the leg fatigue when recommending your run intensity.
