Depending on the style of yoga you practice, you might go to class for years and never do a single sun salutation.  I teach Vinyasa Flow yoga which links movement to breath, and sun salutations are a big part of the practice.  Even if yoga is not your thing, sun salutations can help you warm up for other activities.

Full salutations can be challenging because they require a lot of wrist, arm, and core strength.  I've had very fit active duty folks struggle with Chaturanga (Four-Limbed Staff Pose) and Urdhva Mukha Svanasana (Upward-Facing Dog) because keeping the arms close to the body requires a lot of tricep strength not used in regular push-ups.

Use the modified version to build up your strength. Grab a fellow military spouse to see if you both can complete this challenge, when you have one full sun salutation film it and post the 15-second (or less) video to Facebook or Instagram using #idfitnesschallenge.
