Loads that autoregulate
Slept badly? Crushed it yesterday? Your prescribed weights and volume shift session by session — from your logs, your check-ins, and your wearable if you have one.

A coach who writes to you
Jack reads your week and tells you what it meant — plainly. What moved, what stalled, and exactly what to do about it. No dashboards to decode.
An avatar that earns its muscle
Your avatar grows as you do. Milestones, streaks with a banked rest week, PR moments in gold — progress you can see at a glance.
Real programs, not random workouts
Proven strength templates with warm-ups, progression, deloads, and conditioning built in — then bent around your schedule and equipment.
Example — what a week-3 note from Jack looks like
“Your squat moved 10 lb this week and your last set still had a rep in the tank — that’s the good kind of boring. Sleep dipped Tuesday, so I pulled Wednesday’s volume back 15% instead of letting you grind. Next week we press that advantage: same weights, one more set. Show up.”

Questions
Do I need a card to start the free trial?
Yes — you add a card to start your 7-day free trial, and you're not charged until day 8. Cancel anytime before then in Settings → Billing and you pay nothing. Your history is saved either way.
Is Jack a real person?
Jack — or Jackeline, whichever fits you — is an AI coach built on real strength-programming principles: autoregulation, progressive overload, planned deloads. They read your actual training data, not a script.
Do I need a wearable?
No. A quick morning check-in does the job. If you have a Whoop, Oura, Fitbit, or Polar, connecting it makes readiness even sharper.
What if I'm a beginner?
The on-ramp starts conservative, calibrates your working weights in the first sessions, and progresses from evidence — not ego.
Can I cancel easily?
Yes — Settings → Billing → Manage, self-serve, no emails or phone calls. If you cancel, you keep access through the period you paid for.
