Only takes 4 minutes, but its the longest 4 mins of my life: Burns as many calories as a 40-60 minute run. Makes your body adapt and improve very quickly. Increases metabolism for up to the next 36 hrs. Takes only FOUR minutes, Developed by a Japanese Scientist. NO EXCUSES. 4 minute workout? May have to try it soon.
Another pinner said: "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."
