Stuck in your fitness journey? You don’t know where to start. You’re not sure how to progress. Everyone gives you conflicting advice. Progress feels slow, unbalanced, or fake. Load is the honest fitness app that actually learns you. Cara AI analyses your muscle groups, cardio capacity, body composition, and real training data — then builds the exact plan you need. Set your goals (strength, recomposition, fat loss, muscle gain) and let Cara AI take you there. Key Features: Cara AI Coaching — Builds personalised interval runs, full strength programs, and nutrition guidance based on your actual data. Load Score (0–100%) — The only metric that tells the truth. Combines relative strength across major muscle groups, lean/fat balance, and real progress — no inflated ego numbers. Block Periodization Builder — Create smart mesocycle programs (Hypertrophy, Strength, Power, Deload). Choose Full Body, Upper/Lower, PPL, Bro Split or fully custom. Smart Workout Logger — Fast, accurate tracking with dynamic warm-ups, auto rest timers, RPE/RIR, supersets, and instant PR detection. Muscle Balance & Recovery — Tracks per-muscle strength, recovery status, and ACWR to prevent imbalances and overtraining. Body Composition Tracker — Log lean mass, fat mass, or weight. See clear trends and how close you are to your ideal range. Offline-First — Log workouts, runs, and meals with zero internet. Seamless sync when back online. Full Data Ownership — Export or delete everything anytime. No selling your data. Ever. Load is built for serious trainees who want real, measurable results — whether you’re building strength, recomping, cutting, or bulking. No gimmicks. No lies. Just honest tools that work. https://getload.app/
