If you’re going to the store to pick up the plywood, make sure you take a vehicle that can fit the wood.
Use a permanent marker to mark the spots on the plywood where you want to cut.
Be sure to wear goggles and gloves to protect your eyes and hands from wood
If it’s your first time asking a hardware store to cut wood for you, they’ll most likely do it for free. If it’s your second or third time asking, you’ll have to pay a few dollars. Call ahead to set up a time for you to go the hardware store. You never know how busy they’ll be.
If the wood doesn’t line up, you’ll have to go back and make cuts to change this.
Wipe off the excess glue that drips down the sides of the plywood as you wait.
The goal is to have screws connecting each piece of plywood to every piece of plywood that it’s touching.
The beauty of having a 28 by 24 by 20 in (71 by 61 by 51 cm) jump box is that it gives you 3 separate heights with which to work. You can start with 20 in (51 cm) box jumps and work your way up to the bigger heights with time and practice.
Work in the garage or outside your home and wear a respirator if you have one. If you’re working in your garage, make sure you open the windows and garage doors to properly ventilate the area.
When you land on the box, you want your feet flat and your knees slightly bent.
When you feel like you can consistently make this jump, flip the box over to try a more challenging jump.
Stop doing box jumps once your form fails. Wait an extra few minutes, reset yourself mentally and physically, and then start doing box jumps again. Make sure to focus on your form. 5 quality box jumps are better than 15 bad box jumps.
To improve your endurance and foot speed, flip the box to 20 inches (51 cm) high and do 3-4 sets of 20 reps each. Take a 1-minute break in between each set. This is also a great way to burn fat! Alternatively, you can do a dumbbell press on an exercise ball. When you do it, ensure that your feet can touch the ground firmly. Keep your core tight and posture tall. Start with a weight you are comfortable with for a few reps before increasing to a more challenging weight.
