Don't have and dumbells at home? You can use bottles of water or canned foods (EX:veggies). My dumbells tend to grow legs around my house with having 6 kids living here. Rather then taking the time to try and locate them every day or using it as an excuse "I don't have any so I can't workout today", grab a couple bottles of water or cans of veggies and throw your excuses our the window!!!
My husband finally figured out why there were peas sitting by the computer when he got home from work yesturday when I was chatting with someone and while waiting for a response I picked them up and did a couple reps with them.
