In reply to anonymous123:
It's your choice/judgement whether you decide you want to take falls indoors. Suggest you ensure both you and your belayer are happy with what you'll do, and what will happen. Make sure you're both comfortable with the type of belay device being used.
Search 'dynamic belaying' on here and read the articles. Search 'clip drop' technique too for progressive method of learning how to fall. Be aware of what you will fall into, protruding holds, angle of walls etc.
That said, I think being comfortable climbing above a potential fall is the biggest performance enhancing technique there is.
