Three or more means the program written for a 25-year-old isn't failing you because you're weak. It was never built for this body. Fifteen questions and we'll build one that was.
Start the 15 questions →Your build changes which lifts suit your leverages and how much recovery you need. It does not set your calories — those come from your height, weight, age and activity. Two minutes to find out which one you have.
Longer limbs mean a longer range on every rep. You have been doing more work for the same weight, not failing to build.
You respond fast, which used to cover for bad programming. Around 40 it stops covering — and that is worth knowing early.
You hold onto fuel efficiently and you get strong faster than almost anyone. That is a survival build, not a defect.
Not just a workout app. A full system that connects your training, nutrition, body composition, and recovery into one AI-powered platform.
Your split, your equipment and the movements your shoulders and knees will tolerate. Weights climb as you log. Training is the same whether you are losing fat or building muscle — it is the calories that change, and we show you that arithmetic.
Estimate body fat, lean mass, visceral fat and BMI in seconds. Add a waist and neck measurement and it switches to the Navy method for a sharper read. Re-scan monthly to see what the scale cannot tell you.
Portions scaled to your own calorie target, not a generic day. Swap any meal and the totals update in front of you — and the grocery list rebuilds from whatever you actually chose.
Chat with a coach that knows your profile, scan results, and workout history. Get form tips, meal swaps, recovery advice, or motivation.
LetsBurn Score, weight trends, PR history, body scan comparisons, and calorie targets — all in one view.
Every exercise opens with a suggested weight based on your last session, and shows what changed. Built-in rest timers so you are not guessing between sets.
Answer 15 quick questions about your goals, your joints, your training history and what you have to train with. Takes about two minutes — the more it knows, the sharper your plan.
Get your body fat, lean mass and visceral fat estimated from your height, weight, age and sex in seconds — then track the change every month.
An eight-week block: build for six weeks, deload on week seven, re-test on week eight. Meals and calories are set from your height, weight, age, sex and activity — not from your build.
Log workouts, track PRs, swap meals, chat with your AI coach, and watch your LetsBurn Score climb every week.
Not a generic chatbot. Your coach has access to your profile, body scan, workout logs, and meal plan — so every answer is personalized.
Ask about nutrition, form tips, rest day routines, or how to modify exercises around an injury. Like texting a trainer who actually remembers you.
One paid tier for the food side. 14-day free trial, cancel anytime, no contracts.
Fifteen questions, about two minutes. You get an eight-week plan built around your joints, your equipment, and the days you can actually train.
