Homemade Isometric Tool – Part 2
Following a past entry from early 2009, I’ve received several requests for a portable isometric training device. The piece of equipment discussed in the original entry is obviously too bulky to pack when traveling.
Fortunately, it will only cost a few dollars to build a portable unit. The device seen below was constructed from two lashing straps. I purchased the straps at a local hardware store (Harbor Freight Tools) for $2.99. I then cut a piece of pipe to form the handle. The total cost was less than $5.

One cam buckle forms a foot strap at the bottom of the unit. This anchor point allows me to pull the unit with maximal force. I also add a small piece of rubber padding for a more comfortable fit around my shoe.

A second lashing strap and cam buckle are used for quick length adjustments. I used 12 foot lashing straps to build this unit, but I am only using the full length of one strap. I then cut the second strap to approximately 18 inches. You can see this short piece below at the black arrow. I’m only using this small piece for its cam buckle (which attaches to the 12 foot piece). This second cam buckle allows me to quickly change the length of the first 12 foot piece.
The handle is actually another short piece of lashing strap that wraps through a short piece of pipe. I tied the second lashing strap (18 inch piece) to this handle. The knot is wrapped in duct tape.

I can use this simple piece of equipment to perform several exercises. I can quickly adjust the length of the unit to target multiple joint angles.
Below I am demonstrating an overhead press.
A variety of pulling exercises can also be performed.
If you are looking for a portable isometric unit, this inexpensive option may come in handy. I’ve made considerable strength gains with isometrics for several years now. The simplicity of this tool certainly does not discount its benefits.
