After a cardio/stretch warm-up (5 Min.), this 60 min. workout features 3 cardio +weights intervals (13 Min., 12 Min. & 12 Min.). Each has body-specific cardio, before appropriate resistance-sculpt. The 4th interval (18 Min.) alternates floor sculpt with same-muscle stretches. The diverse choreography has both exercise variety & effective sequencing. Like many high-budget movies, the music was scored to a rehearsal video. Actress/Dancer Sandahl Bergman is a polished performer with excellent technical virtuosity. A fit, attractive cast of 20 with different body types & ages, illustrate Ms. Bergman's easy-to-follow instructions. Appropriate for intermediate to advanced exercisers.
