Excellent exercise device
The OYO is an excellent but small and light weight exercise device. The OYO provides all of the exercise possibilities I wanted in a design that is very easy to take when traveling and does not take up a lot of space at home.
At higher resistance it is a little tricky to hold in place when doing exercise that compresses the OYO, but with practice this is not a problem.
The OYO is exactly what I was looking for and does exactly what I wanted.
