A camera in a home gym — what the AI really does, and what it doesn't

Two kinds of “AI” — and only one of them sees you

When you read the specs of smart strength machines, the word AI appears in all of them. But it describes two completely different things:

• AI that looks at numbers. How much you lifted, how many reps, how long. From that, it works out what to give you tomorrow. It's useful, and it's what most machines have.
• AI that looks at you. A camera that sees the movement itself — your back, your knee, your tempo — and responds to it as it happens.

The difference isn't in how deep the algorithm goes. It's in the hardware: without a camera, there's nothing to analyze except the numbers. Speediance and IMBODY have no built-in camera, and so they have no real-time form correction either — not in this version, and not in a future software update.

What the 42 points do

The system identifies 42 key points on the body — joints, shoulders, pelvis, knees — and tracks them throughout every rep. From this, it derives three things a number on a screen can't give you:

• Symmetry. If one side is working harder than the other, it shows in the movement long before you feel it.
• Range of motion. On a blind machine, a half rep counts the same as a full one. Not here.
• Tempo and breakdown. The moment your form starts to fall apart at the end of a set is exactly the moment injuries happen.

The six-dimension assessment

Before the system builds a program, it measures. The six-dimension body assessment is the starting point — not a questionnaire asking “what's your goal”, but a measurement of where you really are today. The program built afterwards updates based on your actual performance, not a schedule fixed in advance.

Each household member has a separate profile — up to nine — with their own measurements, history and program. A partner who trains twice a week and a teenager who trains five times don't share the same program just because they share the same machine.

Real-time correction — why it matters especially at home

At the gym, there's someone to point things out. In your living room, there isn't. That's why most people who train alone settle into mediocre form and stay there for years — not for lack of will, but because nobody told them.

The system gives feedback during the rep, not in a summary at the end of the workout. And when it detects that a rep is stalling, assist mode reduces the weight instead of leaving you to struggle with it. In an emergency, resistance drops all the way to 0 — there's no physical weight that keeps falling, because there's no physical weight.

Who knows what

What this AI doesn't do

We claim to be the best in this category, and that's exactly why we should be precise about the limits too. Otherwise, the rest means nothing:

• It isn't a personal trainer. The system corrects movement — it doesn't know about your old injury and won't build a competition prep cycle.
• It isn't a medical diagnosis. Pain is a sign to stop and consult a qualified professional, not data to feed into a machine.
• For an advanced lifter, it's a safety net, not a program. If you've been lifting for years and know exactly what you're doing — the main value here is the assist and safety when training alone, not the coaching.
• A camera needs to see. A very dark room or a position that blocks its field of view will reduce accuracy. It's something to consider when placing the machine, and there's a guide for it.
