Squats are considered to be one of the best overall fitness exercises and in particular target the quadriceps muscles. Squat safety bars are used to prevent the need for lifting the weight onto the back. With a safety bar being used, the lifter can position himself underneath the barbell and simply lift it off the rack. Safety squat bars can be expensive when bought from retail outlets. With a few tools and the right materials a homemade safety squat bar can be built relatively easily.
Measure to the centre of the two 3-foot long pieces of wood and make a small mark.
Place the centre of the two 4-foot pieces of wood on top of the 3-foot pieces at the same mark. Ensure they are square by using a carpenter's square. Screw the pieces together using wood screws.
Measure to the centre of the 1-foot pieces and draw a line on one side to the bottom.
Measure 8 inches from either side of the line on the 1-foot pieces and make a small mark at those locations. Draw a straight line from the marks to the top corner of the wood.
Cut along the lines that you made in the 1-foot pieces. When complete, you should be left with two pieces that have 45-degree angles in each side.
Place the 1-foot boards so the angles are flat against the 3-foot and 4-foot pieces; these will act as the braces for the legs. Screw these into place using wood screws.
Find the centre of the braces and place the centre of the 3-foot board at this position. This piece will be used to attach the two sides together. Ensure that the angles are at 90 degrees by using a carpenter;s square and then screw the board into place using wood screws.
Measure 1 foot down from the top of the 4-foot pieces and make marks on the opposite side of the rack from the braces. At these locations place the top of the 6-inch pieces and ensure they are level and at 90 degree angles. Screw these into place using wood screws.
Place the 9-inch pieces against the front of the 6-inch piece to form a "U" shape. Screw these into place using wood screws. This is where the barbell will be placed.
Consider using sandbags to add weight to the base; this will add extra stability to the squat bar.
