If you are looking to enhance your speed with this type of equipment, then you most certainly can and here is how. First off, you need to determine a light enough weight that you can push. The goal here is to not push an astronomical amount of weight as all you are trying to do is increase your speed. Do an amount that works for you and then push the sled for 10 to 20 yards around five times in a set. In-between, take a good 60 seconds or so to catch your breath.
