"Ripped in 30" kicks it up a notch from the "30 Day Shred" DVD. There are 4 workouts, intended to be used progressively as your conditioning gets better. Each workout includes cardio, strength training (using hand weights) and abs. These workouts move quicker than the 30 Day Shred (no activity is done for more than 30 seconds) which I liked. Jillian is a little more intense in this DVD. Level 1 is not quite as easy for beginners as level 1 in the "30 Day Shred." A great workout when you don't have a lot of time.
