Biking is a great way to work your legs without taking a toll on your knees. To work the separate muscle groups in your legs it pays to pedal with clips, or straps, that secure your foot to the pedal.
Emphasize the downstroke: If you push on the downstroke you will work your quads - the muscle in the front of the thigh.

I think the quads are the most over worked muscles in our bodies and they sure do get tight. This standing quad stretch is one of my favorite stretches because you can do it anywhere (I often do it when I am waiting for the elevator when no one is around). In fact I often refer to it as a "portable stretch" since you need no props to do it and you don't have to get on the ground.

The last pose we need to learn for Sun Salutation B is Warrior 1. It is a powerful and grounding pose that strengthens your quads,
calves, booty, and the muscles in your feet. Working these muscles together helps to build knee joint stability.
