Over the past 30 years, I’ve tried almost every kind of workout. But one remains consistent: a series of yoga poses I do first thing most mornings. The routine doesn’t require chanting or opening your chakras. It’s four basic stretches that activate the muscles, open the joints after hours in bed, and clear the cobwebs. Best, the whole thing requires only 10 minutes. Before each pose, take a deep breath and exhale as you move into position. Once you reach your limit, breathe in and exhale again; this helps muscle fibers relax and allows you to go deeper into the stretch.
