Introduction

Jumping abilities and sprinting speed are of immense importance in many sports. The best way to train these muscles is to do plyometrics training. A plyometrics box to jump on and off is a must if you are interested in doing this type of exercise. We’ll show you how to build a wooden plyometrics box in a few simple steps. Plus – once you’ve finished your workout, you can also use the box as storage space for smaller items of gym gear!

Let's go - step by step

Step 1 12

Cut the squared timbers to size

Four long wooden slats are securely clamped onto a work surface. They are being cut to size using a NanoBlade saw.
If you clamp the wooden slats securely, you can saw up to four wooden slats at a time and immediately sand them down.
Four sawn-off wooden slats are clamped securely onto a work surface. They are being sanded down using a multi-sander.
Of course, the sawn edges will then need to be sanded.

You need: NanoBlade saw, Multi-sander, Sanding sheet for multi-sander G120, g-clamps, safety glasses, face mask, ear protectors, 4 wooden slats

You can build your plyometrics box in any size you like. In the following steps, we will explain how to build the larger of the two wooden boxes shown in the pictures.

You will need six boards in total. You can saw them yourself to the given measurements yourself get boards of the right size from your local DIY store.

Squared timbers will be installed on the inside of your box to give it extra stability. To make these, get four additional wooden slats and saw them to the following measurements: 4x 470 mm, 4x 528 mm, 4x 338 mm.

Sand down the cut edges of the squared timbers after sawing them.

Step 2 12

Mark the drill holes

Four wooden slats lie next to one another on a work surface. A measurement is being taken using a protractor.
Drill holes need to be marked on two different sides of the squared timbers. Make sure that the holes are offset.

You need: pencil, protractor

Next, mark the drill holes on the 12 squared timbers. To do so, always place four squared timbers side by side on the work surface.

Measure 5 cm from the right and left edges of all each piece of wood and mark the positions. Always mark an additional drill hole in the centre.

Turn all four pieces of wood 90 degrees. This time, measure 6 cm from the right and left edges and mark the positions. Don’t forget the additional drill hole, which must be offset from the centre by about 1 cm.

Step 3 12

Drill and countersink the holes

Several holes are being drilled in squared timbers using a cordless drill.
In order to insert the screws later on, you first need to drill the holes...
Several holes are being countersunk in squared timbers using a cordless drill.
…before countersinking them.

You need: Cordless Drill, 5 piece-wooddrill-bit-set, HSS countersink bit, g-clamps, safety glasses, work gloves, ear protectors

Next, drill all the marked holes in the square timbers. When you have completed this task, switch to a countersink cutter to countersink the holes.

Step 4 12

Attach squared timbers to the side panel

Two wooden panels are put together to form a 90 degree angle. A marking is being drawn along the edge using a pencil.
Mark the width of a short side panel.
Wood glue is being applied to a squared timber.
The squared timbers are first glued for a more stable hold...
A squared timber is being screwed onto a wooden panel.
...before being screwed together.

You need: Cordless Drill, wood glue, pencil, screws

Now it’s time to work on the boards for the side panels: one shorter, one longer.

Positon the two side panels at a 90 degree angle to one other and mark the edge along the longer panel.

Remove the shorter side panel again. Apply glue to the matching squared timber on the longer panel along where you have made your marking.

As soon as you have done this, screw the squared timber in place from above immediately before the glue dries.

Step 5 12

Attach more squared timbers

Squared timbers are being screwed onto all the edges of a wooden board.
All the edges of the two large side panels must be attached to squared timbers.

You need: Cordless Drill, wood glue, pencil, All the tools, aids and materials you used in Step 4

Next, attach squared timbers along all the edges of both large panels. Follow the instructions outlined in Step 4 for each one.

The squared timbers are screwed in place on the long sides, flush to the edge. Observe the distance indicated in Step 4 for the short side panels on the shorter sides.

Step 6 12

Place the side panel on the bottom panel

Two wooden panels form a right angle to one another. They are being screwed together using a cordless screwdriver.
The side panels now need to be connected to the bottom panel.

You need: Cordless drill/driver, wood glue, pencil, screws, matching bit

Next, connect the two side panels with the squared timbers to the bottom panel.

Start by gluing one side panel in place and screwing it down. Once you have done this, repeat this step for the second side panel.

Step 7 12

Attach the cover

Glue is being applied along the edge of a wooden board.
First, apply some wood glue along the top edges of the side panels.
A screw is being countersunk into the inner frame of a wooden box.
Place the cover on the work surface and place the rest of the box on top of it.

You need: Cordless drill/driver, g-clamps, wood glue, pencil, screws

To attach the cover to the box, start by applying some wood glue along the upper edges of the two side panels.

Next, place the cover board on the work surface and place the other part of the box on top of it. This will make it easier for you screw the side panels down from above.

Step 8 12

Attach the rest of the squared timbers

A wooden box without a cover lies on a parquet floor.
Once you have completed this step, your plyometrics box should look like this from above and below.

You need: Cordless drill/driver, Standard screwdriver bit set, squared timbers, screws

To make your plyometrics box more stable, you should now also screw the four remaining squared timbers onto the remaining inner walls of the box. This will ensure that there is enough space for the two side boards that have not yet been attached.

Step 9 12

Attach the small side boards

Glue is being applied along the edge of a wooden board.
The cover and bottom board only need to be glued on.
A cover is being placed on a wooden box.
If your boards do not fit together precisely, you can use the sander to sand them down a little.

You need: wood glue, Two wooden boards

Next, attach the remaining small boards to the box. To do this, you just need to apply wood glue to the squared timbers and stick the boards to both sides. Allow the glue to dry.

Step 10 12

Trace the hole

A marking is being traced onto the cover of a wooden box using a plate.
You can use a round object like a plate to draw the measurement for the large hole on your wooden box.

You need: pencil, Runde Form (z.B. Teller oder Glas) oder Zirkel

If you want to use the box to store your gym gear as well, you will need to drill holes on both sides.

You can decide how big you want the holes to be. We recommend 200 mm for the large one and 90 mm for the small one.

Use a round objects of the right sizes or a compass to trace the shapes for the holes. Position the holes in the centre.

Step 11 12

Saw the hole

A circle is drawn on the cover of a wooden box. A drill is being used to drill a hole on the line.
You will need to drill an entry hole before sawing.
A circle is being sawn out of the cover of a wooden box using a jigsaw.
The circle can be sawn out very easily using a jigsaw.

You need: Jigsaws, Jigsaw blade T 308 BOF, Cordless drill/driver, 5 piece-wooddrill-bit-set, work gloves, safety glasses, ear protectors

Before you can saw out the holes you have traced, you will need to drill a small hole at one point along the line.

You can now simply insert the jigsaw in the drill hole and saw out the circle.

Of course this step works the same way for both the top and the bottom holes.

Remember that you only have one shot at sawing the piece out correctly. Please saw carefully.

Step 12 12

Sand the hole

The inside of a hole in the cover of a wooden box is being sanded down using a sanding sponge.
Make sure to sand down the inside edges of the hole you have sawn.

You need: Multi-sander, Sanding sheet for multi-sander G120, Sanding sponge, safety glasses, ear protectors, face mask, wood oil

Always make sure to sand down the sawn holes again. Sanding sponges are perfect for this task.

It is usually a good idea to sand the entire box all over. You can also varnish your plyometrics box using wood oil. This will seal it, and can prevent sweat etc. from seeping into the wood.

Now it’s time to "Jump around, jump around. Get up, get up and get down!"
