Four indoor walking workouts led by Bob Harper and previous “Biggest Loser” contestants. For motivation and interest, each workout features a different exercise technique (but you can always return to a “plain walking” option). Bob leads two segments. The first is the basic introduction to walking-style movements. The second is more intense; it includes short “cardio bursts” (moves like speed skating and jumping jacks). Previous show contestants lead the other two sections. Sione Fa integrates dumbbell toning into the cardio. And Tara Costa intensifies her aero/tone segment with a medicine ball. Sunny, outdoor setting. Requires 2 to 5 lb. dumbbells and a medicine ball (a single dumbbell will also work)
