    Step by step

    These steps describe the standard right-handed form without relying on the video.

    1. Face your partner in a crouched, defensive posture, both of you bent forward; take a grip over their back or on the collar with your right hand, sleeve with your left.
    2. Step your right foot between their feet and sit down close, folding back beneath them; your partner's own forward pressure follows you down.
    3. As you roll onto your back, hook your right instep into the inside of their left thigh, lifting as your back meets the mat.
    4. Pull with both hands towards a point past your left shoulder while the instep lifts, steering them over you towards their right front corner.
    5. They roll over you diagonally and land on their back beyond your shoulder. Keep pulling until the roll is complete so they land rolling, not dropping.

    Receiving it

    From a crouched grip fight, your partner sits away beneath you and an instep lifts inside your thigh: your own forward pressure is turned into a roll. You travel diagonally over them. Keep your head tucked to one side, roll across your shoulder rather than your head, and finish the roll onto your back; the momentum wants you to keep rolling to your feet, and you can let it.

    VI judo notes

    Both of you are crouched and gripped, which is contact you already have, and their forward pressure is the signal to sit. Find the inside of their thigh by running your instep up the inside of their leg as you go down. Keep pulling all the way through the roll so they land rolling; from underneath, a partner who stops pulling is how a roll turns into a drop.
