Fitness: One area you may be neglecting is the transversus abdominus - without working it, you may develop a straight torso, rather than an hourglass. Add this to your ab workout: On all fours, back straight, looking down. Exhale completely, hold your breath. Pull your belly toward your spine as hard as possible for 10 seconds, while holding your breath. Inhale. Take a few breaths, then repeat 10 times. Later, you may feel like you’ve been laughing hard - because you worked those same muscles!
