HOW IT WORKS

When you join, your coach gets to know you. You'll answer a focused set of questions about your training experience, physique, schedule, nutrition, sleep, stress, and existing pain. Your coach then uses that full picture to generate a personalized hypothesis about your biggest obstacles and builds a prioritized, step-by-step action plan designed to break through them. You can review the plan and ask for revisions. This is your forge.

AI COACH ALWAYS ON

Fully complete and you have all the tools you need to achieve your goals. AI plans adds a boost to accountability and a personal touch.
Ask about any step in your plan, request a technique breakdown, nutrition targets. Your coach remembers your full profile and adapts every response to your situation.
Weekly check-ins keep your plan current. Progress is tracked right inside the app — no need for spreadsheets or additional trackers.
