A short-but-intense workout that blends aerobics and dumbbell-toning into a non-stop fat-burner. It combines the intensity — and the results — of the legendary 1990’s Firm videos with an updated, fresher feel (e.g. an uncluttered set, some kickboxing moves). It features lots of The Firm’s “four limb movements” that burn fat as they simultaneously tone your upper and lower body (e.g. aerobic-paced lunges with alternating bicep curls). Alison Davis maintains the classic “Firm” experience with a confident attitude and direct, clear cuing (so even her fast-moving transitions are easy to follow because you always know what’s coming). Requires 3 to 5 lb. dumbbells.
