Film it. Find out.
One working set, filmed. It is kept as proof you did the session and counted towards your week — it is not read for faults. The video read judges a full squat snatch, and its tolerances say nothing true about this drill, so snatchlike does not pretend they do. What it does measure, for the drills where speed is the point, is how fast your hands rose and your hips dropped under the bar — kept beside the load, and never judged.
One snatch, filmed from the side. snatchlike reads where the bar went, whether the hips finished, how fast you got under it and how deep you caught it — then names the fault worth fixing and the drill that fixes it.
Your video never leaves this device.
The pose model runs in this tab. What comes out of it is twelve joints per frame with no face among them, and the reading below is worked out here, not on a server. There is nothing to sign into to use this page.
Signed out, the read and its landmarks stay in this browser and nowhere else. Sign in and the reading — and the twelve joints a frame it was taken from, never the video — are kept in your account instead, so a lift filmed on a phone is in the history you look at on a laptop.
Recording a session
- Film one working set, the heaviest one if the load climbs. Up to a minute is kept; a longer recording is trimmed. Once you stop, trim it to the set before it is kept.
- Get your whole body in frame. A recording in which the detector never finds a body is not counted — there is nothing in it to prove with.
- Log what you did once you stop: sets, reps and the load. Leave the load blank if you did not weigh it; it is left out of your progress rather than guessed.
How to film it so the reading is worth having
- Stand side-on to the camera. Filmed from the front there is no forward, so nothing can be said about bar path or foot travel — and snatchlike will tell you that rather than guess.
- Get the whole lift in frame, feet to locked-out bar, from the setup to standing it up.
- One rep. The reading is of a single snatch. A clip with a set in it is read as the one lift it can find.
- Trim it to the lift. A recording or a chosen clip opens in a trimmer first: drag its ends to just before the bar leaves the floor and just after you stand it up, so the walk to the bar is not read.
- Phone on the floor leaning on a plate is fine. This is not a lab; it is a camera at a gym.
- Far away is fine. A chosen clip is read through a crop round you, blown up to fill the detector's view, so a lifter across the gym is read as closely as one in front of the lens — and the playback and the saved video are zoomed to you, not the room.
Trim it to the lift: a second before the bar leaves the floor to a second after you stand it up. Drag the green and red ends, or play it and mark them. Only the part between them is read, up to seconds.
Watch it back
The same twelve joints the reading was taken from, with the bar's path behind them — blue up to the finish of the pull, red after it — and the hip and knee angles at the joints. The path is your wrists: the detector sees hands, not a barbell. It is zoomed to you, however far from the camera you stood. A clip chosen from a file plays underneath, here in the tab. Drag to scrub, here or on the graph.
Save it as a video.
The playback as a file you can post: the bar's path, the angles andsnatchlike.pro drawn in, and a line saying the path is your wrists, because the clip goes where this page does not. It is made here in the tab and saved to this device — it goes nowhere unless you share it yourself.
Send this read.
A link for your coach or a training partner. It holds the skeleton of this lift, not the video — the twelve joints of every frame between the trim's ends, no face and none of the read's words — and their browser reads it again when they open it. It sits after the # in the link, which a browser never sends to a server, this one included.
What it is measuring
Nine things, all of them in torso lengths and degrees rather than pixels, so a clip shot from three metres reads the same as one shot from one and a tall lifter's numbers mean the same as a short one's: how far the bar left the mid-foot, whether the arms stayed long, how far the hips opened at the finish, what the back angle did off the floor, how far your feet travelled, whether the hips got below the knees in the catch, how long the turnover took, whether the elbows were locked in the bottom, and how still the bar was overhead.
The tolerances are conventional coaching margins — the amount a coach would let go without saying anything. They are reasoned from practice, not fitted to anybody's data, and a measurement the clip cannot support is reported as unchecked rather than filled in. The rest of the method →
