I have not competed. What I've gathered from this forum is that it'd be a good idea to take her out to a meet as spectators first, see how she responds and let her decide of she really would enjoy it. Obviously, I'll support her either way.
She has not shown a particular interest in powerlifting, because she's new to lifting and didn't even know it was out there. What I do know, though, is that she'll call me on the phone after each of her workouts excited whenever she hits a new PR...so the desire to get stronger is definitely there. Plus, she has the competitive edge that comes with being in such a low weight class.
Thanks for the input.
