About this app

Train with an AI coach that actually coaches you — set by set, rep by rep.

Arnold Training App is an AI-powered strength and physique coach. Start a live training session and your coach guides you through the workout in real time: suggesting exercises around your goals and injuries, calling your rest timer, reacting to how each set felt, and adjusting on the fly when a joint doesn't feel right. It's built on decades of publicly documented bodybuilding knowledge.

LIVE AI COACHING
• Real-time, conversational coaching through every set of your session
• Exercise suggestions tailored to your goals, experience, and injuries
• Automatic rest timers with countdown cues
• Optional spoken coaching so you can train hands-free

FUEL & MACROS
• Log food by scanning a nutrition label, describing your meal, or entering it manually
• Live daily macro targets — calories, protein, carbs, and fat
• Per-meal targets and reminders across the day
• Supplement checklist

TRACK YOUR PROGRESS
• Body-weight and body-fat tracking with trend arrows
• InBody scan import
• Side-by-side progress-photo comparison
• Workout history with per-set weights, reps, and notes

BUILT AROUND YOU
• Set your goal (build muscle, recomp, and more), focus areas, and injuries once — your coach respects them every session
• Injury-aware: flags movements that could aggravate a known limitation
