In the past few years, we have covered plenty of sleds that can help you build strength in your body. The WOD Wagon is another versatile tool that helps you work on building strength and improving your conditioning. The WOD Wagon is portable and works with dumbbells, barbells, and other training tools.
You can transform this into a dog sled by removing the wheels. This tool has quarter-inch steel base plates and 3-foot upright push bars.
