Loyal Topless Tuesday followers will quickly recognize the "oh-so-purty" mug of Luke Guldan - who was a hit when he was featured as a Topless Tuesdays model. For those of you unschooled to the hotness that is Luke Guldan - let me give you a crash course. Though I give him the title of "Sexiest Man I Feel Like I Almost Know" he describes himself as Professional Bodybuilder / Model / Actor / Entrepreneur. Try saying that three times quickly!

Basically, Luke is a fitness and underwear model with his own website living in New York City. He will be featured in a new 2(x)ist underwear campaign beginning in October which can be found at your local Target store! Additionally, Luke is busy working on another project to keep all of us aspiring to match his well formed physique.

His current project is called Trainers' Tip. I've posted the first two clips below. They are short and well, well worth your time.
