I recently came up with a new idea for exercise that others might enjoy. I happen to love drinking milk, and I usually have a couple of gallons in the fridge. It occurred to me that since the gallon containers have handles, I could use them to exercise my arms with the milk in them.
I just take one container in each hand and start moving them around, making big circles with my arms, lifting them over my head, etc. After three or four minutes, I get a nice burn in my hands, arms and shoulders, then I rest and go again. If I'm staying at my apartment, I do this very quietly since noise will penetrate through to the neighbors', but occasionally I stay at my friend's house where I can play dance music and dance with the jugs, moving them around for the same burn.
I really like it because I don't have the clutter of weights lying around, plus there's something kind of soft and attractive about milk, softer and more attractive than steel weights.
