Raise Big Toes
With raised arches, lift only both big toes, keeping the other four on the ground, then lower them back down. Repeat this slowly 5-10 times. This exercise and the next one require a gradual re-learning of lost muscle control. When you first try, you might not be able to move certain toes independently. Keeping your spine straight and long, you can bend your knees and bend down forward to use your fingers to help hold the other toes down while you are learning the new muscle control.
Crossovers (abs)
Crossovers train the obliques hard by combining rotation with a crunching motion, hitting the sides of your abdominal wall more directly than a straight-ahead crunch. Lying on your back with knees bent, curl your shoulders up and rotate to bring one elbow toward the opposite knee while extending the other leg out. Alternate sides in a controlled rhythm, keeping your lower back pressed into the floor throughout.
Side Crunches (abs)
Side Crunches isolate the obliques, which helps with the rotational power used in sports like football as well as a tighter side-cut look. Lie on your back or side with knees bent and let them fall to one side. Curl your ribcage toward your hip on that side, focusing the movement in your obliques rather than your hip flexors, then switch sides after completing your reps.
