I have a love-hate relationship with Jillian. I have Ripped in 30, 30 Day Shred, and Body Revolution.
Unfortunately, I haven't been able to complete any of her programs. They're good, I know, but I'm not quite strong enough for them. Even level 1 is a bit too much for me, and if I stay at level 1 until I get strong enough to move to level 2, I'll be too sick of it. I did Level 1 of 30DS 6 days a week for about three weeks, and was SICK of it, but couldn't move onto Level 2.
So, right now, I'm doing Leslie Sansone's Firm 30 twice a week, and working my way up. I'll probably add 30DS and Ri30 to the rotation on those two days for variety. As I lose a bit more weight, get into a better workout routine, and get a bit more conditioned, I might try to conquer Body Revolution again. I tried starting it Tuesday, but I realized that I wasn't ready for it quite yet, so I decided to go with Leslie Sansone workouts to start.
