About

Fit puts a trainer's reference behind one connector. An exercise catalogue of 900+ movements from the wger open project — instructions, primary and secondary muscles, equipment, images and video, variations — searchable by name, muscle, equipment and category. A workout-plan generator for 1–6 days a week by goal (strength, hypertrophy, endurance, fat loss, general) and level, using only the equipment you have. Calories burned for 120+ activities from MET values, including cricket, kabaddi, badminton, yoga, bhangra and garba, and household chores. Body metrics: BMI with WHO and Asian cut-offs, BMR, TDEE and calorie targets, Navy body fat, waist-to-height, water and protein. Macro targets by goal and diet with vegetarian and vegan pointers. One-rep max with a percentage table. Karvonen heart-rate zones. Running pace, splits, race predictions and training paces. Keyless; computed locally; nothing stored; information, not medical advice.
