3. Side Balance Crunch
Side balance crunches are an effective exercise but a fairly advanced. It may take some practice to perfect this technique, but it is worth it. A mirror or training partner is helpful in spotting mistakes and correcting form. Keeping your body in a straight line is essential. Do not overextend yourself when lifting. The side balance crunch begins in a side elbow plank. Lift your right leg up and tilt your elbow lightly. Three sessions of ten reps are all you need to firm and tone your waist and abs.
