Early Access“COMPRESS MY WEEK INTO THREE DAYS.”DONE — VOLUME INTACT.
The Sliding Mesocycle
Workouts Slide, Not Fail
For lifters who train seriously four days a week — just never the same four days.
Perfect-week programs quietly reclassify a work trip, a sick kid, or a night shift as a lapse in discipline. HyperIron measures your training block in workouts completed, not days elapsed — miss a day and the entire program slides forward intact. Same progression, same RIR targets, zero failures recorded.
The Problem
Other Apps Fight Against You
Rigid Schedules
Miss Monday? A red X, a broken streak, and a week that's suddenly off-plan.
Endless Menus
Want to swap an exercise? Navigate five screens first.
Dumb Tracking
They count sets, not actual muscle stimulus.
How It Works
Three Steps to Smarter Training
Design Your Program
Tell Claude what you want to build. Training goals, schedule constraints, equipment — have a real conversation and get a periodized mesocycle in minutes.
Train With AI Coaching
Mid-workout, your coach is there. Swap exercises, adjust intensity, compress your week — just say what you need.
Track & Adapt
Every set feeds the progression engine. Volume auto-regulates, fatigue is tracked, and your next session is smarter than your last.
The Talkback Loop
Conversation In. Autoregulation Out.
HyperIron connects to Claude and ChatGPT through a first-party MCP server. This isn't a chatbot bolted onto a tracking app — your coach reads your full history, understands periodization, and every change it makes keeps the mesocycle sound.
I was supposed to do legs today but my knee feels off. Can we swap to upper body and push legs to next session?
YOU
Done. I've moved today's leg session to after your next rest day and swapped in Push Day 2. Your knee will thank you — and your weekly volume is still on track.
HYPERIRON AI
That last set of bench felt way harder than it should. RPE 9 when it was supposed to be 7.
YOU
Noted. I'm reducing your remaining chest volume by 2 sets today and slightly lowering next session's working weight. Fatigue accumulation looks higher than expected.

Example conversation — connect your own coach in ~2 minutes
On your drive to the gym
“I've got a wedding this weekend. Compress my next 3 workouts into 2.”
Mid-workout
“Bench is feeling terrible. Swap it for dumbbell press and adjust the weight.”
Planning ahead
“Replace barbell bench with dumbbell bench for the next two weeks.”
Your AI coach reads your full training history, understands periodization, and makes changes instantly. No screens to navigate. No rigid menus. Just say what you need.
Features
Built For Serious Lifters
True Volume Tracking
A set of bench press isn't just a chest set — it's also triceps and front delts. HyperIron uses percentage-based muscle activation to calculate your true weekly volume.
The Sliding Mesocycle
Life happens. You miss a day. Your mesocycle is defined by workouts completed, not days elapsed. Skip a day, take a vacation, get sick — nothing fails, everything slides, and your program picks up where you left off.
Track How You Train
Real training uses more than just plates on a bar. Resistance bands, cable stacks, machine angles, bodyweight variations, tempo — HyperIron handles it all.
Your Data, Your Way
Your training data belongs to you. Period. Full export anytime in CSV, JSON, or PDF. AI has access to your entire history. No lock-in — if you leave, your data leaves with you.

You keep the full free tier forever: workout tracking, progressive overload, volume tracking, unlimited programs, and CSV export. Premium features pause until you upgrade: AI coaching, advanced analytics, full performance history, fractional volume, template saving and sharing, and mesocycle completion reports. No data is ever deleted, and export always works.
HyperIron integrates with Claude and ChatGPT via MCP — real conversational AI, not rule-based decision trees. You have a natural language conversation about your training, and your coach reads your full history to give contextual advice.
Yes — HyperIron connects to the AI assistant you already use. Connecting takes about two minutes (see the setup guide at hyperiron.com/connect). Your subscription pays for the coaching integration, training engine, and analytics — not for reselling AI access.
HyperIron never sends your data anywhere except your own AI assistant, and only when you ask it something. Whether Claude or ChatGPT retains conversations is governed by your own account settings with those providers — you stay in control.
Yes. The free tier is a fully-featured workout tracker with progressive overload, volume tracking, and equipment profiles. AI coaching is a premium upgrade, not a requirement.
Never. Your training data is always yours — full access and CSV export on every tier, including free. We don’t hold your history hostage.
