Exercise: Big Ass Book Dumbbell
Situation: In the couch
Exercises: Upper arms

Why not use some couch time to work on those biceps? If you have some dumbbells then then use them, but if you don’t there’s still no excuse. You can use anything you have laying around which carry some weight and you can hold with one hand. For instance a big ass book.

Grab your big ass book with one hand and support the elbow on your knee. Do a few sets on each arm and then switch.
