Following a few recent discussions on the forum (here and here), I decided to make a pair of softball pull-up grips. A quick search of the web brought up one commercial option that retails for over $70. The DIY model will cost closer to $10.
To begin, I purchased two softballs for a total of $6, and then two eye bolts with a nut and washer for each ($4). The eye bolts are 6 inches long and 3/8″ thick. I drilled a hole through each ball and then screwed in the eye bolt. The drilled hole should be slightly smaller than the eye bolt to ensure a tight fit. I then added a washer and nut to the protruding end.
To attach the grips to the pull-up bar, I made two connectors with chain and a spring clip. Other attachments could certainly be used, but I already had these on hand.
Next, you can see how the connectors attach around the pull-up bar:
If you are looking to add some grip work to your pull-up routine, these grips are an inexpensive and effective option.
These grips can also be attached to rings for body rows.
For approximately $10 and ten minutes of your time, these grips make for a very easy do-it-yourself project.
