I bought into the DDP Yoga program. My total after a 1-week trial will be $86+. I did the 45 minute intro workout today, which is a slow burn movement introduction.
I'll be 65 in April, very inactive and about 45 pounds overweight. I found the initial video challenging enough for me, but also doable. Most traditional yoga workouts are so far beyond my strength and flexibility limits that I can't really get a good workout. DDP seemed to be a combination of modified yoga and isometrics.
I'll track my progress in weight and workout, and report back.
