The simple act of planning when and how you'll sweat each day makes you more likely to get off the couch and on the move, a study in the Journal of Consumer Research reports. Celeb trainer Kathy Kaehler (who works with Jennifer Aniston, Julia Roberts and other busy bold-faced names) created this workout formula for speedy weight-loss success. Actress Tiffani Thiessen shed her 45 pounds and got back to her prebaby weight with Kaehler's cook once, slim down all week plan and gave this get-lean routine a try.
Plug one (or two) of the fat-burning, muscle-sculpting moves from each category, right, into the routines below to map out your daily downsizing. We gave you the weekends off, but if you need to skip a weekday, swap in a sweat session on Saturday or Sunday.
SWEAT: Power Punch
Stand with feet hip-width apart; bend elbows so forearms are parallel to floor, hands in fists in front of you.
SWEAT: Sizzling Shuffle
Stand with feet hip-width apart, knees soft, hands at chest level, palms out. Shuffle three steps to left; do a side lunge, reaching left hand toward left foot (as shown). Stand and repeat to right. Continue, alternating directions for 1 minute. Repeat twice.
Stand with elbows bent, upper arms tucked close to body. Circle forearms as if swinging a jump rope, and hop from one foot to the other, tapping heels on floor (as shown). Continue for one minute. Repeat twice.
LOWER BODY: Leap & Lunge
From standing, jump forward, landing with knees soft (as shown). Stand, then do a reverse lunge with right leg. Return to standing; repeat reverse lunge with left leg for one rep. Do 12 reps. Repeat once.
LOWER BODY: Tiptoe Toner
Stand with feet hip-width apart, arms raised in front of you at shoulder height, palms down. Rise onto balls of feet (as shown) and hold for one count; squat, holding for one count. Do three sets of 10 reps.
