AI strength training for busy founders.
45-minute Heavy Duty sessions built on Mike Mentzer's HIT principles, planned, timed, and tracked by an AI coach that adapts to your meetings, travel, and stress.
A training console, not a logbook.
Everything you touch mid-set is one tap: weight, reps, the failure toggle, log. Rest is timed for you. Nothing else is on the screen, because nothing else matters between sets.
- Large numeric inputs you can hit with shaking hands
- Automatic rest timer tuned to the lift
- PR detection acknowledged, not celebrated with noise

That's a genuine plateau, not noise. Drop to 87.5 kg, own 4 x 7 to failure, and extend top-set rest to 3:00. I've staged the change for Friday's Push A.
| Date | Top set | Est. 1RM |
|---|---|---|
| Apr 2 | 92.5 kg x 6 | 110.7 kg |
| Mar 26 | 92.5 kg x 5 | 107.9 kg |
A coach that reads your numbers, not a cheerleader.
The coach sees every set you've ever logged. It spots plateaus, adjusts load and rest, and stages program changes you approve with one tap - in plain, professional language.
- Answers grounded in your actual training history
- Programs adapt to stress, sleep, and travel
- Changes are staged, never silently applied
Audit your strength like revenue.
Estimated 1RM, personal records, and consistency tracked like business metrics - calm charts, real deltas, no vanity numbers. If the line isn't going up, the program changes.
- Strength progression across every lift
- Consistency scored on frequency, progression, and volume
- Time saved versus traditional training, quantified
Built on Mike Mentzer's Heavy Duty principles.
High-intensity training is the inverse of the fitness industry: less volume, more intensity, full recovery. It was designed for people who don't have time to waste.
Brief
One working set to failure does the job of five half-efforts. Sessions end in 45 minutes because more wouldn't help.
Intense
Every set is taken to true muscular failure - the only signal that reliably forces adaptation.
Infrequent
Muscle grows between sessions, not during them. You train every 4-7 days, calibrated to your stress and sleep.
From assessment to first session in five minutes.
Take the assessment
Seven questions on your goal, lifestyle, stress, sleep, and experience - the inputs that determine recovery capacity.

Founders who stopped skipping training.
"Two sessions a week and my numbers finally move. The first program that respects a board calendar."
"The coach told me to train less. It was right - every lift is up since February."
"I stopped negotiating with myself. The console makes the session frictionless, so it happens."
"I built FitEntrepreneur because I was tired of choosing between building my business and building my body."
