COACH, HUMBLE, etal, TOO much info here ... but .....
Flex's new gym is located in the vicinity of Blue Diamond Road (exact address unknown by myself at this time.)
Blue Diamond is the road that runs from the south Las Vegas Blvd to the desert town of Pahrump.
If you know where the Silverton Hotel/Casino is located, Blue Diamond runs along the backside of that facility and you can possibly(?) see the Silverton in the nearby background of one of Flex's videos while he is talking outside of the gym.
It's interesting that "Dragon's Lair" is also the name of one of the gift shops in one of the Strip Casinos and is also the name of an outfit which specializes in the captive breeding and sales of monitor lizards, Green Tree Pythons and new Calidonian geckos, both of which I have been told are in Vegas but may be closed down due to the pandemic.
I should also say that EOS is open big time here in Vegas and doing great business (parking lots always packed) and the newest EOS gym/club(?) recently opened on Blue Diamond with $10/month memberships.
My unprofessional guess is that Flex's DRAGON'S LAIR will cater to top notch competitors within any sporting endeavor ..... Local, national, and international as well.
And that EOS will continue to be a big success if their membership fees reamain stable. (Presently $10/month.)
Best of Luck to FLEX and his new business in LV!!
