just read on a blog where two traing partners once a week go to their high school track and carry a 50# sandbag. they carry it on their right shoulder for a while, then carry it just holding it in both arms, then its on thre left shoulder, etc. as long as they dont stop walking and it dosent hit the ground. they started with a lap, and over a few months time they are up to almost 2 miles. then he said they fall to the track in exhaustion with their heart rate almost at max.
i never tried this, but it sounds like a good workout. is it really that tough, and does the heart rate really get up that high carring a 50# sand bag a mile or two?tthanks for any comments
