The Jiu-Jitsu Challenge has been issued and is underway, with onetime “Baywatch” star Jeremy Jackson leading his newly formed crew in getting their feet wet in gentle art competition .

And they’ll be diving in head first: With no prior experience but determination a-plenty, Jackson, his fiancee, Loni Willison, and the rest of the troop will take on the American Cup Jiu-Jitsu tournament in just three months’ time, showing how there’s no better way to face one’s fears than through Jiu-Jitsu.

Still only just starting out in their preparations for gi-clad combat, the initiative has already inspired others across the United States to follow suit.

Registration for April 28-29 American Cup, in San Jose, California, is already open at americancupbjj.com. Sign up for a chance to test your mettle and get to rub elbows with celebrities, to boot.

Rickson Gracie used to say that Jiu-Jitsu is a vast ocean, so you’d better try and be a shark, even against opponents who hardly know how to swim. Or something like that.

So the actor Jeremy Jackson, once on the hit TV show “Baywatch,” took up the challenge of diving into this ocean by signing up for the 5th installment of the April 28-29 Claudio França-promoted American Cup  in San Jose, California, and he got two cronies to join him, with no gentle art experience and just 90 days to prepare.
