Building Plyometric Boxes (Plyo Boxes)

Building Plyometric Boxes (Plyo Boxes)

Plyometric boxes are essential in plyometric exercise. The exercise help in increasing speed and strength. For the lower body plyometric exercise, you often need a box that you jump on and off. If you frequent the gym, it is possible that a plyometric box is available, bit for someone who works in a garage, I doubt it. Buying yours is even expensive, imagine having to send about $150 on something and then you even have to go through the stress of fixing it when it arrives, too much stress. There is no need to worry, you can make your own DIY plyometric box for less than fifty dollars. Amazing right, let us see the steps and materials needed to make our own plyometric box.

Design

We would be following a very simple design.  Here, all the sides are exactly the same size, each one overlapping one another,  while being overlapped by the one on the other side.  Each side is in essence ‘falling’ into another side, but they all lock into one another and create a solid structure. Going by the measurements, it is possible that the sides are angled inwards, so, we would use a bevel of the same angle on the top and bottom to make sure that the bottom rests flat on the ground, and the box top has a flat surface to sit on.

 

Measure And Cut

First, you should measure the panels for the box and mark these edges. Using a ruler and a pencil, join these markings together. This way, you have a straight line to follow with your circular saw.  Follow the lines closely, and cut the panels with your table saw or circular saw if you have one. It is important to follow the lines, this ensures that your panel lines up when it is time to fix the box. If you have trouble working with this, test it out on a piece of scrap wood. This is because, when you start cutting,  you need to know exactly where your blade is going to enter the stock.  The best way to do this is by grabbing  a scrap piece of wood, and putting your straight edge on it.  Then put your saw against it and make a shortcut.  Now measure the distance from the straightedge to the edge of your cut.  You’ll need to offset your measurements by that much. Make sure you cut in the same direction, if not, the sides would not be parallel and that would ruin things.

 

Lay Down The Panels And Sand Them

You need a total of nine panels. Six of them would make up the box and the remaining three would serve as reinforcement inside the box. Sand the panels, using an orbital sander and 220 grit paper. Depending on you, you can cut handles for the box at this point. Decide where you want the handles so it is taken away from the middle, as there would be reinforcement from the middle. To make the handles, draw 1 1/4 inch by 4 inch box, use a drill bit to create a small hole big enough for the blade of your jigsaw or for a router bit. Cut the hole for the handle using a jigsaw.

 

Assemble.

Join the wood together, make sure to use a glue when you are assembling the box together. Use a drill with a 1/8 inch drill to drill  holes before you add screws. This should prevent the wood from splitting. Continue around the corners, use 2 inch long wood screws at each corner.

 

Add reinforcements

It is not really necessary to add reinforcements but they are needed for extra strength. Draw a line that can go straight from the middle down. A panel should  go right while the  nth brother, will go to the other side.  The smaller panels are dismantled so you would be able to add screws for each panels. Make sure you glue the panels before attaching the bottom Part of the box.

 

Add the reinforcement

Put the reinforcement where it is meant to be. Glue each end and put it in the box. Usually, if it is a tight fit, then, a screw might not be needed. Also, it would not budge once the glue dries as long as it is tightly fit. Then, secure the final panel and close the box.

 

Sanding

To sand the box, use a 220 grit sand to smoothen the edges. If it appeals to you, you can fill the screw holes with putty. However, if you do not fill the holes, remember to  sand away the extra.

 

Customize

Once you finish your plyometric box, it is time to customize it. You can customize by painting. Remember to wear your respirator, and make sure the area is well ventilated it is safety first. Then, coat the box evenly using Red Spray Paint. Since we are using two colors, the first color is complete. You should measure 1 1/2 inches in from each side you’d like to add the second paint to. Use a painters tape to mask  the borders.  Ensure that the spray paint is completely dried before taping it. Apply two coats of Black Hammered Finish. When the back pint starts to dry, remove the tape. Do not wait for it to finish drying, that way, it is neater.

 

Complete

And this is how you make your very own plyometric box. And now, you would be one of the manliest me in the neighborhood.
