No time to make it to the studio for a 90-minute yoga class? A little
goes a long way, so even if you throw in five minutes every day, you're
sure to notice a difference within a week. These five poses focus on
the arms and upper back, and because you hold each one for one minute
(twice as long as you normally would in class), taxing your muscles in
such a way will make you feel that warm burn we all love that lets us
know we're really working.
