Anyways, I have wanted some gymnastic rings for different kinds of pullups, pushups and reverse rows. They are a great piece of fitness equipment. You can buy them from Elite rings for $80 or make them for a fraction of the price. Here's how I did it.
Step 1: What you need & Prices
2 x 12 feet lashing straps (Harbor Freight Tools: $3.99)
20 feet of 244 lb capacity nylon rope (Harbor Freight Tools: $1.47)
2x 1" x 24" pvc pipe (Home Depot: $1.43 each)
A 1 gallon paint can
Step 2: Get started
Take two 3-4' lengths of the twine and get it wet so it won't burn in the oven. Put each length through the pipe and cap one end with duct tape.
I used cloth athletic tape which didn't work so well. Twine will work much better.
Step 3: Fill 'er up
We are filling it with sand so as the piping is bent it won't kink.
