The Ultimate Lunch-Hour Workout

Crab Dip

Targets: Shoulders and triceps

• Sit on floor and place hands on floor on either side of hips, fingers forward; position feet hip-width apart in front of you, knees bent 90 degrees, feet flexed, heels on floor.
• Press through palms to lift hips about 4 inches off floor, balancing body between heels and hands.
• Bend elbows and lower hips toward floor until butt barely touches, then straighten arms to return to start.
• Do 15 reps.

Target tip: Don't cheat: Keep your weight over your hands instead of your feet. It's a small move, but it works!
