Dr. James Vegher (co-owner of Precision Physical  Therapy & Fitness) and Fitness Director Dustin Miller take it to the next level this week by expanding on last week's basic tip on properly engaging your core muscles. Watch and learn as they add some resistance to this concept and challenge Dustin's ability to maintain proper form while bringing the heat: the weight of his arms and legs. If this exercise is easy, regardless of your fitness level, you are doing it incorrectly. We recommend practicing this movement for 10 -15 minutes per day or until you cannot maintain correct form due to fatigue in the lower abdominal area being exercised. This simple movement is a great alternative to crunches or traditional ab building exercises that advocate pulling your belly button to your spine while engaging your core, a movement that will unequivocally weaken your back and could even cause permanent damage. Happy muscle building!
