Like rubbing your belly while you pat your head, these firming multitaskers take major concentration.
Do this routine twice a week, three times through so you can work your mind and your body. Who needs Sudoku?
1. Think On Your Feet
Works: Shoulders, Arms, Hips, Glutes
Stand with feet hip-width apart and palms forward, a four- to five-pound weight in each hand. Rest left-hand weight against left hip. In one motion, raise right arm to right side until parallel with floor and lift left leg to left side (as shown). Return to standing and repeat on opposite side. Alternate for 12 reps. If you’re wobbling, stare at a spot in front of you to stay steady.
2. A+ Abs
Works: Arms, Abs
Lie faceup with knees bent, feet flat, arms by sides, palms down. In one motion, straighten left leg and lift toward ceiling as you reach right arm toward left foot (as shown). Lower to starting position and repeat on other side. Continue for 12 reps. To protect your neck, keep your chin up — imagine you’re holding an orange between your chin and your chest.
3. Smarty Swimmer
Works: Arms, Back, Glutes
Lie facedown with arms and legs extended. Raise chest as you simultaneously lift left arm and right leg (as shown). Pause, then return to start. Repeat on opposite side for one rep. Do 12 reps. You’ll instinctively want to lift all your limbs at the same time, but resist the urge — stare at your hands and move slowly.
