it's funny you mentioned that the first time I went to a boxing gym they thought I looked like I knew what I was doing so had me spar with the most experienced guy.
The guy comes in to hold...dips low...my hands go round the back of his head and my facking leg twitched..I nearly kneed the fella in the face..goes to show how well we've been trained The guy didn't see it but my mum who bless her likes to keep an eye out for me did.

Finding a good gym is hard. There are lots of gyms but you need to click with the people, trainer, or you're just treading water.
