The best gym is the one right outside your door. From race training to routine jogging, running is a great full-body, mind, family workout. The BOB Ironman jogging stroller is perfect for sprinting, endurance training or just a nice long walk with your kiddo. The Ironman stroller features a fxed front wheel providing increased stability whether jogging or speed training. 16” semi-slick, air-filled tires on lightweight aluminum alloy wheels mean that this stroller is built for speed just like a road bike and the hand-activated front caliper brake adds control when jogging downhill.
