You've been trying to squat like the person in the video. It doesn't look the same, and it doesn't feel right. That's not because you're doing it wrong — it's because your body has different proportions. Leg length, torso height, arm span: these change what every exercise looks like and how hard it feels. STATURE shows you the physics in plain language, so you can finally understand what your body is doing.
Free. No sign-up. Runs entirely in your browser.
Most beginner confusion comes from comparing your movement to someone with different proportions and assuming you're doing something wrong. Long legs make squats look different. Short arms make deadlifts feel harder. Tall people have a longer path from floor to lockout. None of this is a flaw — it's physics. STATURE turns those physics into something you can see and understand, without needing a biomechanics degree.
Answer five plain-language questions about your body and you'll get a clear explanation of what your proportions mean for your lifting. The best starting point if you've never thought about body mechanics before.
See which stance width, bar position, and grip suit your body for each major lift. Stop using setups from videos made for different proportions — start with one that actually fits you.
Enter your height and weight and watch an animated holographic figure move through any lift with your proportions. It's the clearest way to understand what your body is actually doing under the bar.
No jargon. STATURE explains every result in plain language — what your proportion profile means, which lifts suit your body, and why some exercises feel harder than they look on video.
Not at all. The quiz walks you through everything in plain language. For any result STATURE gives you, there's a plain-language explanation of what it means and why it matters. You don't need a background in physics or anatomy.
Start with the proportion quiz. It takes about five minutes and gives you a plain-language summary of your body's strengths and challenges for lifting. From there, the compare tool lets you see an animated figure with your exact measurements moving through any lift.
Almost certainly not. Most YouTube tutorials are filmed by people with specific proportions, and their technique reflects their body — not yours. STATURE shows you what an ideal squat looks like for your proportions specifically, which will look different from a generic demonstration.
Just your height, weight, and sex. STATURE calculates all your segment lengths — femur, tibia, torso, arms — automatically from those three inputs using research-backed ratio tables. If you want extra precision later, you can input measured segments directly.
STATURE focuses on the biomechanics of your body proportions and their effect on movement mechanics — not on specific weight prescriptions. For programming (how much to lift and how often), a coach or a structured beginner program like Starting Strength or GZCLP is the right tool.
Yes, the core tool is completely free. The proportion quiz, comparison tool, and animated figures are all free. STATURE Pro ($49 lifetime) adds advanced features like saved profiles and training logs — but you can get enormous value from the free version.
Plain-language explanations, proportion quiz, and personalized setup recommendations — free.
