Key takeaways

  • Weekly sets per muscle group are tracked from your Hevy data. The AI compares against the 10-20 sets/week range that research links to optimal hypertrophy (Schoenfeld et al., 2017).
  • Body composition from Withings (weight, body fat, muscle mass) is tracked alongside training data. You can see if your bulk is adding muscle or just fat.
  • The AI watches for the minimum effective volume for each muscle group - enough to grow, not so much that you can't recover.
  • Deloads are timed based on recovery data and performance trends, not a fixed calendar.

AI Bodybuilding Coach

Track your volume per muscle group, monitor your 1RM trends, and use body composition data to see if your training and nutrition are actually driving hypertrophy.

Volume per muscle group tracking

Every exercise is categorized by primary and secondary muscles. The AI tallies weekly sets and compares against evidence-based targets. If your side delts are at 6 sets/week and research suggests 12-16 for growth, you'll know about it.

Progressive overload monitoring

Estimated 1RM trends for all your lifts are tracked. The AI catches when progress stalls on specific exercises and suggests changes - different rep ranges, new exercise variations, or adjusting rest periods.

Body composition correlation

Withings scale data shows your weight, body fat, and muscle mass trends over time. The AI connects these to your training data. If muscle mass is plateauing despite high training volume, it might suggest you're under-eating or need a deload.

Split optimization

Based on your training frequency, recovery capacity, and time available, the AI recommends the best split for you - whether that's push/pull/legs, upper/lower, or a bro split. It adjusts volume distribution to match.

Frequently asked questions

How does AI bodybuilding coaching work?

Connect Hevy for your gym data and Withings for body composition tracking. The AI monitors your training volume per muscle group, tracks progressive overload, and correlates everything with body composition changes. It sends coaching feedback on Telegram.

Can it track my bulk or cut?

Yes. During a bulk, it monitors weight gain rate and body composition to make sure you're gaining muscle, not just fat. During a cut, it watches for strength loss and muscle mass decline to keep you in a sustainable deficit.

How does it know which muscles are lagging?

It counts weekly sets per muscle group from your Hevy data. If your back is getting 18 sets/week but your hamstrings are at 4, the imbalance is obvious. It also looks at strength progression - muscle groups where your numbers are stalling may need more volume or different exercises.

Does it help with exercise selection?

Over time, the AI sees which exercises drive the most progress for you individually. If your chest responds better to incline work than flat bench, or your quads grow more from leg press than squats, it'll suggest programming around what works for your body.

Can it design a workout split?

Yes. Based on how many days you can train, your recovery data, and your goals, it recommends a split that distributes volume across muscle groups appropriately. It adjusts as it learns your individual recovery capacity.
