Last week, your challenge was to perform 300 side lunges. How did you do? Side lunges make you sore in new places, don’t they? This week, I want you to add a curtsy lunge to your side lunge. Watch the above video to get the proper form. Make sure, as always, that you are keeping your knee over your foot in proper alignment. For more of a challenge, add in the balance element that he talks about in the video.
