Doing chair pose is almost like the yoga version of doing squats. However, it can be easier on your knees because you will be holding a steady position instead of jerking them up and down. Start by standing with your feet about hip width apart, and extend hands overhead. Squat down without extending your knees too much past your ankles. Look forward, hold in your abs, and press through legs to engage your butt muscles. Breathe deeply, holding this pose until you can’t anymore. Try to go for 1 minute to start.
