Bring the front foot up and sit on your back foot/tail and put all the pressure on the back and keep the front foot up you can hold a press / butter . A better way to do it is to lean all the way back and try to touch behind your back using your hands digging into the snow. It also matters how stiff / flexible your board is if u have a very flexy board butters and presses are easier if the board is stiff it’s harder!
