Step forward and across with your left foot; roughly 2-3 feet in front of and a few inches to the right of your right foot.
Slowly lower your body directly in between your feet until the thigh of your left leg is parallel with the floor and your right knee is almost touching the ground. Keep your upper body perpendicular to the ground, and both feet facing forward as best you can.
Both knees should be at or around a 90` angle and your left knee should never come over the toes of your left foot; try to keep your left knee directly over your left ankle through the entire motion.
Slowly push through your legs to return to the standing position with your feet together.
Repeat the motion, this time stepping forward and across to the left side with your right foot. Complete the same number of repetitions on each side.
The Crossover Lunge is a great variation of a traditional lunge. Not only does it help tone and strengthen the Butt, Hips and Thighs but it also builds great lateral support through the knee, ankle, and hip joints. This is a great exercise for home workouts since it needs no equipment and can be done virtually anywhere. Make this exercise more difficult by holding extra weight but be careful, always err on the side of to little weight versus to much to protect your knees.
