Bicep and tricep exercises
Use dumbells if you are not in a gym, its complex to explain the exercises in words but in attendance are several fitness sites that will show them within pictures, you requirement tricep extensions, tricep presses, tricep dips, overhead tricep exercises plus the traditional bicep lift, soon see results, I did!
What I do is hold 2 tins (like beans) one in respectively mitt, stretch out within front afterwards bend arms to touch your shoulders. down to the floor any side of your body next up to the shoulders , above your come first. after start over again.
Do this as regularly as you can each day. this tightens up the 'floppy bits'
