Jillian goes through 6 or 7 circuits depending on how you look at it (warmup, stretch, and one kindof partial circuit at the end). The warmup is nice-mostly cardio (jogging, jump rope) and some dynamic stretching. Each circuit has a few moves and then you repeat the circuit. Jillian does a good job of hitting all the muscles in this one! I really feel that everything was thoroughly worked after doing this.
Most of the circuits are done standing but the last 2.5 are done on the floor and include: plank twists, plank taps, push ups, effective lying ab work variations, donkey kicks, lying inner and outer thigh raises, bridge, supermans, plank rows, and side planks. I love (to hate) all this plank work-you can really feel it working your entire core, chest, shoulders, tri's, and more!
The standing work includes moves like: lunge w/ a bicp curl, squat with an overhead press, static sqat w/ a concentrated bicep curl, pliet w/ an overhead tricep extension, static squat w/ tricep kickback, deadlift w/ hammercurl, surrenders while holding your dumbbells over your head (yikes), sidelunge w/ a hammer curl, etc. I liked all the variety and she does lots of multimuscle moves that got my heart rate up decently.
I would rate this a solid intermediate workout, if you use heavier weights you can easily get a more challenging workout, I did! Jillians got her typical "tough guy" attitude in this, but shes not over the top. If you are not a fan of hers, you probably wont enjoy the workout. But she is fine w/ me, the workout is solid and unique. I like it better than 30 Day Shred, but not as much as BFBM.
