# How to Build a Weight Sled

A weight sled is an excellent and extensively used exercise equipment to train for a particular sport, remain fit or as an effective means of conditioning. Pulling it increases the overall effect of your cardio exercise program. It can be built in its simplest form, with the help of a piece of plywood attached to an automobile tire. Ideally use an old tire but thoroughly wash and clean the old tire first. If an old tire is not avail then buy a used one from your local junk yard. Building a weight sled is a fairly simple and easy project which can bring about great benefits to your health as well as lifestyle.

## Tools and Materials Needed:

• Drill bit
• Automobile tire
• Eye bolt
• Washer
• Fastening nut
• Measuring tape
• Piece of plywood
• Pencil
• Jigsaw
• Sandbags, weight plates and rocks (optional)

## Step 1 - Drill a Hole

Use a drill bit which is approximately the size of the eye bolt (that you will be using later on) to drill a hole through the middle of the tires tread. Go about this step gently and carefully so as to prevent any irreparable damage to your tire.

## Step 2 - Fasten the Bolt

Place the eye bolt within the hole. Position it in such a way that the eye of the bolt faces your tire’s outer side. Screw the fastening nut of your bolt to secure your tire’s tread. Also insert and fasten a washer which shall assure that the bolt remains safely in place.

## Step 3 - Get the Diameter Correct

Using a measuring tape, calculate and determine the overall diameter of your tire from one tread to the next. Also measure the diameter of your tire’s opening. Add up both the diameters and divide the final figure by two to find out the average diameter of your observed calculations.

## Step 4 - Sketch a Circle

Sketch a perfect circle on your purchased piece of plywood. Go about it by tying a thread around a pencil’s edge and pressing the string through the center of your plywood. Assure maintaining a distance from the respective pencil which equals half the diameter you calculated in Step 3. Use the pencil to draw a complete circle around the focal point, preserving the tautness of the string.

## Step 5 - Cut out the Plywood

Use a jigsaw to cut out the circle you drew on your plywood. Try to accomplish this with as much accuracy as possible. Once cut, insert the plywood into the tire.

## Step 6 - Put up Weights

Load your sled by piling up weights through your tire’s opening. Place them on top of the shelf created by your plywood. All materials like sandbags, weight plates and rocks can be used for your weight sled. It is also worthy to note that no matter how safely constructed your weight sled is, it does nonetheless, carry a minute risk of injury if not used with thorough caution or proper care.
