After I had a baby and my husband was deployed - I obviously had ZERO time to go to the gym. I lost 65 pounds by the time he came home - THIS was my arm workout every day. And ooooooh boy did it work. 10 sets of 10 every day & each of my arms has lost 7 inches since giving birth. Proof you don't need a lot of time or money or equipment to change the way you look.
