HAGANE | BIG3 Form Analysis

A service that estimates the skeleton from squat, bench press and deadlift videos and lets you check your form as numbers.

A skeleton is estimated from a deadlift video taken with a smartphone, and trunk lean angle, knee joint angle and the position of the bar relative to the joints are quantified for each repetition.

Output is limited to observable facts. No pass/fail judgment, no injury prediction, no joint load estimation. This is not a medical service or a diagnosis.

Six key frames from the same deadlift video, each with the skeleton, trunk lean angle, knee joint angle and bar-to-joint positions overlaid

Key frames of the video

All videos and figures shown are actual output from our in-house systems. No images or videos generated by generative AI are used.

SESSION01

Service overview

A skeleton is overlaid on the video, and trunk lean angle, knee joint angle, the position of the bar relative to the joints, and the boundaries of each repetition are quantified. After review by a specialist, you receive an annotated video, a comparison at the same phase, and three prioritized points.

SESSION02

Scope of service

SESSION05FAQ

Frequently asked questions

Does the AI score the lift automatically?

No. The system estimates the skeleton; the review and the points are made by a specialist. No score or pass/fail is given.

Will it tell me about injury risk?

No. Skeleton estimation is observation, not diagnosis. If you have pain, please consult a medical institution.

Where is my video stored?

On your own device. Footage entrusted to us for review is returned to you, and nothing without consent is published or used for training.
