Led by veteran instructor Violet Zaki, this interval program burns fat and builds lean muscle by alternating cardio with toning.

The workout has two different 21 to 23-minute segments — you can play them separately, or in sequence for a more intense calorie burner.
The first segment features short intervals and targeted body sculpting.
The second section emphasizes longer intervals and multi-muscle group toning (eg a lower-body dead lift combined with an upper-body hammer curl).

All the cardio blasts are high-intensity and high-impact (but you also get low-impact options).
This DVD comes with a 16-page Cooking Light recipe book. Requires 3 to 5 lb. dumbbells.
