Stationary bikes have been around for decades and have improved in design and function over the years. They have been proven to provide weight loss and health benefits if used consistently and correctly. They offer a good cardio workout if properly used, and many come with built in features such as an adjustable platform and computerized workout to help enhance the effects of your exercise routine. There is some jarring and joint stress involved with running, on a treadmill or other type of home gym. This type of equipment is to place your forearms flat on each armrest, with your back fully extended on the ball. Tighten your abdominal muscles and then lift your torso up off the mat toward your knees. Return to the original position with your back flat on the mat. Relax your abdominal muscles and then repeat. Remember to breathe during the exercise.
