Right, so we know sprinting is one of the best things for conditioning and sledge work for GPP. So, I'm wondering from a conditioning point of view, if I had say a 300m incline at like 20 degrees and 'sprinted' (I use the term loosely due to the distance and what I'm about to suggest) up it dragging a sled behind me, would this be a good supplement to HIIT work for GPP and overal muscle strength (with everything being a supplement to MT) I'm thinking of a lifting belt (and/or dipping belt) and attaching the sled (when I make/buy one) to it via chains. Couple of years ago I was doing the car pushing for 200m stretches and I thought it'd be good to mix it up again
Sounds like a great workout for your leg muscles and cardio if you ask me, I keep meaning to make myslef a sled as there's a big stretch of grass about 2-300m long just around the corner from me which would be perfect. If you want to see more on the subject Dave Tate wrote a whole article (although its more from a PLing point of view so its pretty thin on cardio, more a active recovery/work capacity focus) which has a bit on different dragging techniques to work different muscle groups. http://www.t-nation.com/readTopic.do?id=459405
