Here's a great unilateral exercise that helps to strengthen the adductors and vastus medialis oblique (vmo).
Stay as upright as possible.
Allow the knee on the front foot to shoot as far past the toes as possible (the knee not traveling past the toes is a myth) but don't allow your heel to come off the floor on your front foot.
Perform all the repetitions on your weaker leg before switching to your other leg.
gluteus medius gets a good charge too as a stabiliser
