Built, tracked, and adjusted — every week.
Zerxus lays out each session with the right lifts, sets, and target loads, learns from what you actually log, and — on AI + Coach — a real trainer leaves notes right on your plan.
AI exercise swap
Tap any exercise to instantly swap it with an AI-suggested alternative that targets the same muscles — based on your equipment and training history.
Training cycles & phases
Structured multi-week programs with distinct phases — accumulation, intensification, peaking — so your training has direction, not just workouts.
The speed of AI. The judgment of a real coach.
Pure AI apps are fast but can’t truly know you. Human coaches are insightful but expensive and slow to respond. Zerxus gives you both: an AI that designs, adapts, and answers instantly — with the option to have a real trainer review your plan and refine it.
- 01
AI builds & adapts
A complete program in minutes, adjusting to every session you log.

Your pocket trainer
Ask anything, anytime. The AI knows your program and history, and answers in context.
- 03
Real trainer review
On AI + Coach plans, our trainers look over your plan and add expert suggestions.
Built for you — or for your clients
Everything your training needs
AI-built programs
Complete, periodized 8-week programs tailored to your goal, schedule, and equipment.
Personal AI pocket trainer
Chat with a coach that knows your program, your nutrition, and your full history — ask about form, soreness, or strategy — or just tell it to swap or shorten today’s session and it updates your plan on the spot.
Real trainer review
On AI + Coach plans, a human trainer reviews your plan and leaves personalized suggestions.
Progressive overload
Smart weight suggestions based on how your last sessions actually went.
Personalized history
Every set, PR, and trend remembered — so your coaching gets sharper the longer you train.
Fast logging
Log weight, reps, and effort in seconds — by voice, text, or photo. Snap a meal and let the AI read the macros. Built for the gym floor.
On-device form check
Record a lift and get instant feedback on depth, tempo, and position — processed privately on your phone, never uploaded.
Nutrition tracking
Log every meal by voice, text, or photo. Track calories, macros, and key micronutrients like iron. Your nutrition AI knows your training schedule — and your strength AI knows what you ate. Everything works together.
Your first session in minutes
Tell us your goal
Experience, training days, equipment, and what you’re working toward.
Get your program
AI builds your plan instantly. On AI + Coach, a trainer reviews and refines it.
Train, chat, adapt
Log sessions and just tell your coach — “my shoulder’s sore,” “I’m short on time” — and it changes today’s workout instantly.
Real results, real people.
“I’ve tried five different training apps. Zerxus is the first one where I actually feel like someone knows my training. The AI pocket trainer answered a question about my shoulder at 11pm that would have taken days to hear back from a PT.”
“The trainer review on my first program caught that I was doing way too much volume for a 3-day split. One note saved me weeks of spinning my wheels. Worth every penny.”
“I use Zerxus to build programs for my clients faster. What used to take me 45 minutes now takes 10. The AI does the heavy lifting, I just add my coaching layer on top.”
The best of both worlds.
