It's an exceptionally well-sequenced set of varied body-sculpting exercises. Jillian encourages fastest results by carefully alternating different multi-muscle exercises (e.g., one set of muscles rests which allows another set to exert maximum intensity). These exercises really do focus on common trouble spots: the back of the arms, thighs, and abdominals (get rid of those saddlebags and muffin tops). These almost cardio-speed moves are very well transitioned with no wasted, between-move downtime. Jillian's cuing is very hands-on; she is both demanding and supportive (a little friendlier than the TV show). Requires 3 to 10 lb. dumbbells. ©2008.
