weight vest experiment

I borrowed a 20 lb weight vest from my friend yesterday so that I could hopefully build up my leg muscles a little bit. I wore the vest for an hour and realized it was a little too heavy so I took some weights out so now it only weighs 10 pounds. I can definitely feel the weight of the vest on my shoulders and back and on my legs when I walk up stairs. I hope after a couple of weeks my shoulder and back will get used to the weight so I can add more weight and reap the benefits.
