Too lazy to go to the gym nearby, and since my father threw out all the weights we had I'm using a damn backpack to do some "backpack curls" and reverse "backpack" curls.
The advantage would be that I can easily change the weight, by adding or removing some books and , measuring the weight w/ backpack, and subtracting the amount from my original weight.
