Lower Body Workout

My lower body workout is my version of the " Body for Life" lower body program. I combine twenty minutes walking on the treadmill with a four set lower body workout.
4 sets of leg presses followed by one set of quad extensions; 4 sets of leg curls; 4 sets of toe raises. I do ab work on leg day - 5 sets of 60 crunches, followed by one set of side crunches.
