Philadelphia's Muay Thai Mecca

Welcome to Stay Fly Muay Thai, the Philadelphia Muay Thai Mecca and home of Justin "The Purple People Eater" Greskiewicz. The awesomest place to get awesome. Awesome.

Training in Thailand

Early this spring, before it starts to really get awesome outside, we’re gonna avoid the tail end of the cold. When there will probably still be snow on the ground from the patented Northeast late winter blizzard that we all have grown accustomed to, we won’t be here. Those frigid temps that seem to keep Punxsutawney Phil in his hole every February 2nd will be left behind. Why? Because we’re headed to the land of smiles, Thailand. 

This March 12th through March 26th, I will be hosting a camp at Khongsittha in Thailand. It’s open to everyone, not only to Stay Fly members, but I would love to have a few familiar faces come with. 

If you’ve ever been interested in training in Thailand, this is your perfect opportunity.  The training here is awesome. The accommodations are comfortable, and the itinerary is packed full of the good stuff. 

We’ll spend solid hours in the gym, smashing it. We will go on a few trips to see some stuff in the area. We’ll get a real taste of the areas surrounding Bangkok, and we’ll be among friends with similar interests. 

It really is an awesome opportunity to get a ton out of a trip. 

Here’s the link to the trip, so you can get an idea about it.

Stay Fly, homies,
