Both of these tapes have a similar format. They have short warm-ups and cooldowns and 30 minutes of aerobics. Even though the routines are taught more briefly than usual, they can be picked up fairly easily by the experienced exerciser. Sometimes coordinating the arm and leg movements can be difficult on the Hi/Lo tape. The choreography is in Kari's usual style, dancy but not overly complex. I like the one on one style of these tapes. These tapes are for the self-motivated, serious exerciser who doesn't need an MTV format, loud music and a gimmicky setting or costumes to be motivated to exercise. They are only 40 minutes each so they can be combined with a toning tape, like Kari's Tone It Up, for a total body workout.
