Resistance bands are crappy. Someone bought me one for christmas when I was 14, and believe me, at age 14, I was very strong. Well, needless to say, it lost it's resistance within 2 months.
I just do lots of military push ups, chin ups, tricep push ups, and heavy lifting. Try beating egg whites into a stiff peak with just a dessert fork! It took me a whole day.
