Why athletes choose FORGE

Every tool you need to actually improve.

Built with competitive athletes and certified coaches. Not watered-down wellness content — real training infrastructure.

AI Programming Engine

Your personal coach learns from every session. Adjusts volume, intensity, and exercise selection based on your performance data — not a static template.

Based on your HRV this morning (48ms), I've reduced today's squat volume by 15% and added a mobility warm-up. Your strength should peak Thursday.
Makes sense, I felt stiff yesterday. What about the cardio block?
Swapped it for Zone 2 steady-state — 25 min at 135–145 BPM. Better recovery stimulus than HIIT right now.

Streak Engine

Consistency compounds. Track your training momentum with smart streaks that account for active recovery days.

Common questions

Everything you need to know

No. Forge Fitness generates workouts for your exact setup — bodyweight at home, dumbbells, or a full gym. You select your equipment during setup and all workouts are built around it.
During onboarding you tell Forge Fitness your goal, experience level, available time, and equipment. Every workout is generated specifically for those parameters using Claude, Anthropic's AI. No generic plans — everything is built for you.
HRV (Heart Rate Variability) measures how well your nervous system has recovered overnight. A higher HRV means you're ready to push hard. A low HRV is a signal to train lighter or rest. You log your HRV reading from Apple Watch, WHOOP, Garmin, or Polar — and Forge Fitness gives you a specific training recommendation for the day.
No. You can use any HRV-capable device — Apple Watch, WHOOP, Garmin, Polar, or any app that measures HRV. You manually enter the reading and Forge Fitness interprets it. Native Apple Watch sync (automatic background reading) is coming with our iOS native app.
You get full Pro access for 14 days. A credit card is required to start the trial, but you won't be charged until the trial ends. You can cancel at any time before the trial ends and you won't be charged anything.
Yes. Cancel anytime through your billing portal — no questions, no friction. Your access continues until the end of the current billing period. We also offer a 30-day money-back guarantee on your first charge.
Yes. Your workout history, weight log, HRV readings, and nutrition data are stored locally on your device only — never uploaded to our servers. We don't sell your data or use it for advertising. See our Privacy Policy for full details.
Both plans include identical features — unlimited workouts, HRV analytics, nutrition tracking, coaching messages, and everything else. The yearly plan is $59.99/year ($4.99/month) vs. $17.99/month, saving you 72%. We recommend yearly if you're committed to the long game.
