Q: Is shooting a slingshot frequently a good lower arm exercise? It has those really thick rubberbands too! Thank you.

A: That's a tough one. I suppose It could be a decent forearm exercise, but it really depends on how strong the rubber band is and how much tension you're creating in it. See for yourself: if you can draw it 15 times or so back-to-back without rest in between fairly easily, then it's not much of a workout for you.
