20.57 - push-ups and planks are two body weight exercises that work your arms.
He estado intentando ganar músculo en el brazo, pero no tengo pesas. ¿Alguien me puede recomendar ejercicios con mi propio peso corporal?

Push ups are a great exercise. Isometric exercises, where you essentially provide your own resistance are also great. For example, press your palms together, hard, for 10 seconds. Rest and repeat.
