Your first routine is one sentence away. Tell Mighty Nimble what you need — "20-minute upper body with dumbbells," "my lower back has been tight," "quick warm-up before a climb" — and get a complete, personalized routine in seconds. Use text or your voice. No menus. No templates. No scrolling through exercise lists. BUILT FOR YOUR BODY Every routine is shaped by your profile — age, fitness level, equipment, health conditions, and goals. A leg day for someone with a knee injury isn't just missing squats. It's a fundamentally different routine, designed around your body. ANY DISCIPLINE. ONE APP. Strength training. Mobility. Yoga. Sport-specific conditioning. Rehabilitation. Warm-ups and cool-downs. Other apps are siloed into one discipline — Mighty Nimble covers all of them, and you can combine them in a single routine. EDIT BY CONVERSATION Don't like something? Say so. "Make it shorter, drop the burpees, and add more core work" — your routine updates instantly. One change or ten at once. The AI rebuilds around what you want. PLAY WITH GUIDANCE Tap play and go. Timers, countdowns, and audio cues guide you through every set and rest period. Start anywhere in the routine. Skip ahead. Pause. Your workout, your pace. SHARE WITH ANYONE Every routine can be shared with a link. The recipient sees a clean, visual workout in their browser — no download needed. Great for trainers sharing with clients, friends swapping routines, or sending a warm-up to your climbing partner. ORGANIZE YOUR WAY Folders let you group routines by goal, sport, time of day — whatever works. Each folder can have its own settings: different equipment, fitness level, health considerations. A "Travel" folder with bodyweight-only. A "Morning Mobility" folder for flexibility. A "Client: Sarah" folder with her specific needs. GETS SMARTER OVER TIME The AI learns from your history — what you ask for, what you change, what you keep. Your routines become more personalized the more you use it. MIGHTY NIMBLE PLUS Unlock extended-thinking AI that uses your full context for deeper precision, unlimited routines and folders, workout insights and analytics, and priority generation.
