I pushed my bike up hill the other day. We were "mountain biking" on a relatively level dirt road that had a big hill in the middle. Man, pushing my bike up the hill was more tiring than I expected. Maybe if I had some kind of wheeled thing, a wagon or something, that I could load up with stuff and push it or pull it up my steep driveway that would provide a good workout. I've never seen a prowler and don't even know what it looks like. We don't have anything like that at my gym. I'd just get in the way in the gym if I tried pulling a plate with a rope or something like that.
