Okay, so I've had this prowler for a little bit. It's fucking awesome and kills me. I'm wondering though, if any of you have favorite programs with it or with tire dragging or sled dragging that you'd like to share with me. I'm using it with all my rugby athletes to develop penetrating running with people tugging on them (snicker...) Should I use it at the beginning of practices to develop straight speed and power? Or should I use it for conditioning at the end to wear them out? Let me know what you think.
