Boarding
One of the easiest (and cheapest) ways to increase the lockout portion of the bench is to employ the board press.
With a simple trip to your local hardware store, the 2x6's and wood screws needed for a 5, 4, 3, 2, AND 1 board are LESS than $30. *We've gone up to a 7 board for Big Jon who's wingspan is just over 80".
