The Single leg Squat and Dead-lifts are two of the most challenging, but beneficial leg exercises. These exercises forces the stabilizers of the lower leg to work in ways they are not used to thus allowing them to strengthen and better protect you. This move takes both exercises, and puts them together. Give it a try, master it and your legs will not only look amazing, but they will feel SO strong.
Watch this video then start by trying the move with no weight. Do three sets of 12. As your form improves and you feel more stable throughout, then add weight. Make sure to sit back and keep your knee behind your front toe.
