Obliques
This is an excellent first stretch for the core muscles of the torso and, in particular, the external obliques.
1. Stand with your feet shoulder width apart.
2. Bend your arms directly overhead. With each hand, grip your the opposite elbow.
3. Lean slowly sideways until you feel mild tension along the side of your trunk. Bend at the waist, while remaining still below the waist. Don’t lean forward or backward, only sideways.
4. Hold this stretch for ten seconds, then return to the starting position for a few seconds.
5. Perform a secondary stretch for another twenty seconds.
6. Repeat this stretch toward the other side.
