Not really sure where I should post this, so I hope this is alright. I was looking into getting resistance parachutes to build up my sprints, for general leg development, and maybe to throw into my training week as an anaerobic cardio of sorts. I know many of you favour sleds, but that is not really an option for me.
So can anyone recommend a good site where I can buy reasonably priced resistance 'chutes? And also, when they list the approximate resistances, is 30lbs a lot for doing wind sprints?
