This exercise works the muscles of the inner thigh (adductors). It is very easy to perform, and only requires a set of dumbbells and a workout mat. The good thing about the dumbbell thigh lift is that it not only builds strength in the legs, it also promotes flexibility.

From a seated position, place the bottoms of your feet together. Grasp a dumbbell in each hand and place one on the inside of each knee. Slowly lift your knees as high as you can, then lower them back to the starting position. Repeat the exercise for several repetitions.
