Notes About the Project:

  • A jigsaw or bandsaw will be needed to cut the notches in the supports
  • Sanding is totally optional… With repeated use of the plyometric box for workouts, the wood will smooth itself out!

Step One

Cut the pieces for the box: the top and bottom, sides, ends, and supports. Mark the position for the notches on the supports, and cut using a jigsaw. Sand the pieces if desired!

Step Two

Pre-drill countersunk holes along all four of the edges of the top and bottom pieces. Also drill countersunk holes along the 14-1/2″ edges of the end pieces as well as along the center (the 14-1/2″ direction) of the end and side pieces to secure the support.

Pro tip: Position the countersunk holes and screws about 2″ from each end to avoid conflicting with screws from the opposing side.

Apply a bead of glue, and place a side piece on the long edge. Insert and drive 1-1/2″ screws to secure. Repeat for the opposite side.

Apply a bead of glue along the 14-1/2″ edges of the end pieces. Place the end pieces between the side pieces, and secure in place using 1-1/2″ screws.
