I can't speak to the effectiveness of the actual workouts because I signed up for it and promptly forgot about it. I am very active and love to exercise. I just never got into DailyBurn. However, I think a company screams scam when you enter your credit card information and never hear from them again. I had a subscription for three months and never got a single email from them. If they were really interested in keeping me fit, wouldn't they be emailing me and reminding me to work out and fulfill my fitness goals? Once I canceled, the emails started to stream in asking me to return and asked me to work out with them. I was so turned off at that point. I would never recommend it to anyone.
Bottom Line: No, I would not recommend this to a friend
