How about ankle weights? I've hear that 5 or 10 pounds around your ankles is the same as using a 30 pound pack.
I am wearing heavy RAT boots and using a pack. I need to build up the shoulders since we will be wearing packs when I get to the Combat Training Center in Cali next week. Training to go train. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" /> Well, I just rotated the laundry into the dryers, so I have 45 minutes to finish my circuit. About 4 miles.
