Stand up tall and take a big step froward so that when you bend your knees your front knee stays above the ankle. Try to get deep enough in the lunge position that your back knee touches the floor, or comes close. Then step the back leg to meet the front and continue forward.
PLANK TO LIZARD
This is a really great hip opening exercise. Start in a plank position and raise one leg to try to bring your foot to the outside of your hand on the same side. (If your hips are too tight to be able to reach your foot to your hand, you can grab your low chair or ottoman to modify) Once your foot is next to your hand, start to sink into the movement by lowering your hips toward the floor. Breathe deeply and try to move with your breathing. Come back to plank position and repeat on the other side.
