Farmers Walk Revised
Above is my latest farmers walk design. For most people, this is overkill. I had the unique requirement of not being able to drop the weight from a great distance. If your not working with a weight you might drop, the lift is of limited value. It was made with 1 inch pipe. The top piece is 48 inches and the down bars are 24 inches. Floor flanges hold the weight on. It works great, and for me rides about 4 inches off the floor, creating a very safe device. I added pieces of pvc that give additional grips of 1 7/8 and 2 3/8.
If you can drop the weight, several good ideas exist. One of the best is to use two super curl bars. That is what I was using before I made the above. They work great, as long as you can drop them. I also REALLY like the design found here. The cable bar guy also has an excellent design here. My original design can be found here (though I would recommend one of the others). You can also use dumbbells as described here. Just be REAL careful to miss your toes, if you drop them!
