Robert Garrity 5 I came off of 3 years of arrhythmia and finally dieted and made other changes to get myself slim. However, I was pathetically weak from the inability to exercise. The OYO gym was the perfect solution to building up from almost zero. I completed the 10-wk course last week and am already raring to start the next challenge. OYO means 'On Your Own': I was, but with the follow along videos, I wasn't... OYO rocks!
