Sorry for the belated update, but wow! DDP Yoga is probably the best choice I could have ever made for myself regarding what to do for exercise. After the first week, I broke through a plateau and dropped three and a half pounds - maybe that doesn't seem like a ton at my weight, but I'd been hovering around the same number for way too long! I feel great since I've started. Once you learn to engage properly, it's really easy to break a sweat practically standing still! It's amazing to get my heart pounding without killing my knees like I used to. I can already notice increased flexibility, too. In short, this program is absolutely amazing and I don't think I'll ever look back! I highly, HIGHLY suggest this to anyone like me who needs to get cardio in without the joint pressure.
Once I've lost more weight, I'm sure I'll start incorporating other types of yoga. I'm officially hooked!
