A different starting position
New angle. Fixed seat.
The backrest moves from seated to reclined. The seat cushion keeps its angle while the backrest moves.

It starts with the starting position
Deep start. Big movement.
The roller starts well beneath the seat. The acute starting angle defines the beginning of the movement — follow the arm from this deep position through its full path.

STOAD 01 / Physical prototype
Watch the prototype in use.
From reclined to more upright. See the backrest positions and the adjustment beside the seat in a real gym.
Physical prototype · video
26 seconds from an actual demonstration. Reclined and more upright setups, with closer views of the adjustment beside the seat. No audio.
About the recording and its evidence
The clip shows visible use and adjustment of the prototype. It does not measure hip/knee angles, capacity or lifetime. The recording date and prototype version are not published. The description was checked against the clip on 5 September 2026.
Open the original clipTwo setups. A closer look at the adjustment.
Seated – more upright
The user exercises with the backrest in a more upright position.
Reclined setup
The backrest is lowered, and the user exercises in a more reclined position.
Adjustment beside the seat
The user leans forward to operate the adjustment beside the seat.

Research context
Why adjust the hip angle?
The rectus femoris crosses both the hip and knee. That makes backrest position an interesting starting point for product development.
A ten-week study of 22 untrained men found greater growth in parts of the rectus femoris at 40° than at 90° hip flexion. It tested another machine; it does not establish the effects of STOAD 01.
