Charles - Gym Strength Coach
Build Muscle, Workout Plans
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Charles is the best strength coach you can find online.
Most gym apps just log the workout you already planned. The catch is, you have to know what to do. Charles does that part for you. He learns how you train, writes your full plan, and tells you exactly what to do every time you walk in.
Stop guessing. Just train.
WHAT EARLY LIFTERS SAY
"I never have to think about training plans anymore. Charles takes care of the structure, the focus, and the progression, so I can just show up and train." - Daniel Mercer
"I had a shoulder injury and was nervous about training again, but Charles helped me ease back into it slowly and safely. I'm finally rebuilding confidence and strength." - Emily Hartwell
"I travel a lot for work, so the holiday mode has been a game changer. It keeps me consistent without making training feel impossible when I'm away." - Marcus Bennett
WHAT YOU GET
• A plan written for you. Not a random workout generator. Charles builds your whole plan around your body, your experience, and your goals.
• It changes as you do. Every week Charles reads what you actually lifted and adjusts what comes next, so you keep getting stronger.
• Trains around your pain. Something hurts? Tell Charles and he swaps the movement. No pushing through injuries.
• Built for your gym. Tell Charles your equipment and he plans around it. Real exercises for the kit you have.
• Holiday Mode. Away from your gym? Charles gives you quick sessions so you never fully stop.
HOW IT WORKS
1. Assess. Answer about a dozen quick questions about your strength, history, equipment, and any injuries.
2. Get your plan. Charles builds it on screen. Your first phase unlocks right away, the rest unlock as you progress.
3. Train. Open the app, follow today's session, log your sets, get stronger, and get on with your day.
A REAL COACH, WITHOUT THE PRICE TAG
A good coach who actually programs for you runs $150 to $300 a month. Charles gives you that coaching for $9.99. Try everything free for 14 days first.
WHO IT'S FOR
Beginners who want to start right instead of guessing. Lifters who outgrew random workout and set logging apps. Anyone who wants a real plan that changes as they get stronger.
WHY STRENGTH
Lifting 30 to 60 minutes a week is linked to a 10 to 17 percent lower risk of early death (Momma 2022, British Journal of Sports Medicine). You are not just chasing a number on the bar. You are getting your healthy years back
Charles speaks seven languages: English, German, Spanish, French, Italian, Portuguese, and Turkish.
