1. Knees-to-Chest Stretch
While lying on your back, pull both knees up to your chest while simultaneously flexing your head forward until a comfortable stretch is felt in a balled-up position. Hold this position for 15 to 30 seconds, and then return to your starting position.
2. Trunk Rotation Stretch
Lie on your back with your knees bent and your feet flat on the floor. Keeping your shoulders firmly on the floor, roll your bent knees to one side. Hold for five to 10 seconds, and return to the starting position. Then repeat the exercise on the opposite side.
3. Hamstring Muscle Stretch
Lie on your back and grasp your left leg behind the knee. Raise your leg up to 90 degrees with your knee bent. Attempt to straighten your knee with your toes pointed back toward you. Repeat this exercise with your right leg.
4. Arm Cross Stretch
Extend one arm out straight in front of you. With the other hand, grab the elbow of the outstretched arm and pull it across your chest, stretching your shoulder and upper back muscles. Hold and then release. Repeat with your other arm.
