Stretch like a cat for 30 to 60 seconds when you roll out of bed each morning. It’s like hitting a reset button on your body. Get on all fours on the floor and curl your back toward the ceiling like a frightened cat. Hold for 10 seconds, then bend in the opposite direction, lowering your bellybutton toward the floor while keeping your arms straight, hands directly under your shoulders, and your thighs perpendicular to the floor. Catlike stretching first thing in the morning improves posture, promotes blood flow, and relieves body tension, according to the Mayo Clinic.
