Good luck to Jaimito, at Milonga Para Tres, in his experiment:
"There is a common belief among some people that it is impossible, or at least very difficult, to be in incredible shape and have a comfortable embrace. ... So right after I get stuffed tonight for Thanksgiving dinner, I'll start an experiment to get incredibly ripped, and still have a comfortable embrace, which will be verified through pictures and through the opinions of milongueras who dance with me."
Go for it! The common belief, incidentally, is bollocks. It's certainly possible to be in pretty good shape and have a great embrace. I haven't closely inspected the six-packs of any of the dancers I'm thinking of, so I can't tell you for certain how well defined they are, but I can think of several definitely fit men with definitely working tummy muscles and beautiful snuggly embraces. And fat men who you just bounce off of, boinngg.
I also happen to know that if you train in the right way, it is possible to use your tummy muscles to make the woman laugh. However, I don't advise you to try this unless you're pretty sure she's going to.
