What is the circumference of the handles?

Hello John, Thank you for your question. The diameter is about 1.38in, which brings the circumference to roughly 4.3in. Please feel free to call us directly at 925-350 -4111 should you have any other questions. With best regards, Your WorldFit Team

Can you do leg exercises barefoot or will the strap be too uncomfortable?

I personally like to use sneakers, but I use sneakers that I don't wear outdoors, or I clean the soles of my sneakers so that I don't mess up or dirty and degrade the straps while using them. The better you take care of your equipment the longer it lasts. Using bare feet could get a little uncomfortable.

How exactly do you workout your chest with this? Also, is there any way to actually measure your progress?

You can train the chest by shortening it up and positioning it across the back to perform a forward press. This device doesn't really provide a way to measure progress. It is a relatively cheap and portable isometric exercise device. It's best use is for travel or a quick workout when pressed for time. Probably not well suited to a stand alone routine.

Will this work witha Bullworker Classic?

Hello Peter Shmidt, Thanks for your inquiry. No, the WorldFit ISO Trainer is a stand-alone training device. With best regards, Your WorldFit Team
