FORMA

FORMA is a free AI fitness platform that helps anyone train smarter. Its AI workout builder creates a personalized plan from your goals, experience, and equipment; an interactive 3D muscle map and 105 step-by-step exercise guides show you exactly how to train each muscle; and 12 free calculators (TDEE, BMR, one-rep max, strength standards, body fat and more) handle the numbers. What makes FORMA different is Life-Load — an adaptive readiness score that reads your sleep, stress, and daily schedule and reshapes today's workout so you train smart, not just hard. Everything is free with no signup required, works in 14 languages, installs as a mobile app (PWA), and even offers a free public API for its exercise and muscle database.
