The moving step "Ji" Press movement in the Ba Fa Wu Bu 8 Energies 5 Directions form gives many students a lot of difficulty. This movement is about channeling a slingshot force through the body. In order to do that, we have to be like a water hose dialing in the water output from a large spray into a very narrow stream so the force is concentrated. This is why we don't turn our bodies and point our feet in the direction of the press. Most students stomp their foot and push out their arms in the Ji movement. That's not it at all. You should feel a slingshot force rip through your body.
