I am now glad I did not sign up for her site. I got on her mailing list a few years ago and get regular emails that I occasionally dig through for pep talks or recipes. I think that, along with the workout videos I enjoy, is enough Jillian for me.
habakuktwo: I've personally had good experiences with some of her workout videos, specifically the 30 day Shred, Ripped in 30 and No More Trouble Zones.
I didn't enjoy Burn Fat Boost Metabolism that much but that's just because I'd rather go for a run or take a dance class then do a 45 minute cardio workout in my basement. It was a good workout though. I also wasn't thrilled with the abs one.
I haven't done the kettle bell one because I've heard iffy things about it and didn't feel like buying a kettle bell. I also have not done her yoga.
Balance in all things.
