Here is a short yoga video (or yoga interval) I shot for triathletes, cyclist and runners. The cool part is it really works the psoas, quads, hamstrings, and glutes. It is meant to be a restorative interval but it can also be used to strengthen the legs in a balanced way. And the best part is it only takes about 5 or 6 minutes to go through 2 or 3 times. Although in truth this simple interval is pretty challenging so one time through may be plenty. Restorative, strengthening yoga in 6 minutes or less? How's that for effective time management?
