“We hung this net obnoxiously low and you need to crawl under it.” Best way to train: Duck Walks. Sure they look a little funny, but nobody will be laughing when you make this obstacle look like a joke. Do 100 yards of duck walks also at a random interval during each run. As for your resistance training—deep squats. So long as you're injury free and have the mobility to make it happen, going below parallel is very beneficial for your knees. Deep squats will prepare your quads, knees, and back for the awkwardness that awaits you. 3 x 10-12.
