Before buying a jogging running system, make sure you’re clear on what you’re getting. This is easy to do with the Baby Jogging Travel System from Doctor’s Choice. The system has two treadmills to move your body and a cross-country bike for exercise. In addition to the running machine, it has an abductor trainer and calipers to work on balance and posture issues. However, don’t let this fool you into thinking that it is only for fitness or even the gym–the system can be used at home or outdoors in your yard or backyard.
