LIFTBACK Comes with a “lift” mechanism. Allows each pad to be driven upward. The degree of lift is determined by setting a pin in one of three slots. The first slot locks it down. The second and third slots allow 5” and 8” of upward lift.
“The coaching point is to teach a player to roll and sink his hips, and get full arm and leg extension!”
RAMBACK Comes with a “ram” mechanism. Allows each pad to be driven back and then lifted up. Only after the pad is driven back 3” will it release and lift up 3”.
“The coaching point is to knock a defender off the ball and get leverage on the block!”
