Zerxus: AI Strength Coach

Zerxus

About this app

Zerxus is an AI strength coach in your pocket — with real trainers in your corner.

START FREE — 30 days, no card required.

Zerxus builds you a personalized strength program with AI and adapts it as you train and recover. When you want a human eye, real certified trainers review your plan and add their suggestions. It's coaching that thinks like AI and cares like a trainer.

WHAT YOU GET
• AI-built training programs personalized to your goals, experience, and equipment
• Programs that adapt week to week with RPE-based progressive overload
• Recovery-aware training — a 10-second morning readiness check (sleep, energy, soreness, stress) tunes today's session so you push when you're fresh and back off when you're not
• On-device Form Check — record a set and get an instant form score with a rep-by-rep replay. Runs entirely on your phone; nothing is uploaded
• An AI coach chat that actually changes your plan — say "swap the deadlift, my back's tight" and it updates today's workout, not just the conversation
• Optional review of your program by real strength & conditioning coaches
• Nutrition tracking with full macros and micros — log a meal by photo or voice in seconds
• Built-in rest timer, set logging, and last-performance tracking
• A personal AI coach that remembers your full training history

HOW IT WORKS
1. Tell Zerxus your goal, history, and the days you can train
2. Your AI coach builds a complete, periodized program
3. Train, log your sets, and watch the plan adapt as you get stronger — and as you recover

WHO IT'S FOR
Whether you're returning after a break, chasing your first 100kg lift, or training around an injury, Zerxus meets you where you are.
