Marzia Prince, Healthy Housewife and fitness trainer, brings us the walking side squat today, intensified by the use of a rubber band. You can do a walking side squat without the band, but the stretching rubber engages more muscle groups in our hip flexors, legs, abs, and glutes. Go into a low squat, go wide, and then bring it in while keeping your core tight to get the most out of this exercise. Amplify your workout with a medicine ball to provide more weight, tighten your core even more, and work your arms.
