Fire up your muscles from head to toe.
This do-anywhere workout takes only five minutes—so you can knock it out on a busy day or before a party. Here’s what you need to know:
YOUR TRAINER: Bob Harper, celebrity trainer and host of the The Biggest Loser, which starts in January on NBC.
YOU’LL NEED: A pair of dumbbells heavy enough to challenge you. Start with 5- to 10-pounders.
DO: This workout up to seven days a week. Do 90 seconds of the broad jump (see below). Rest 10 seconds, then do 90 seconds of any other move. Rest 10 seconds, then complete 90 seconds of any other move of your choice. Rest for 10 seconds. Repeat the sequence for 5, 10, or 15 minutes a day.
Now onto the moves…
Works legs, glutes
Stand with feet shoulder-width apart. Squat, then explosively jump up and forward (as shown), landing softly, feet under hips. Repeat.
Works arms, core, back
Stand with feet hip-width apart, holding dumbbells at sides. Bend knees slightly and tilt forward at hips, back flat, arms straight, hands under shoulders. Bend elbows and lift weights toward chest (as shown). Extend arms and repeat.
