When it comes to picking fights, you’ve been known to battle it out over just about everything.

An unanswered phone call. A wet towel on the floor. A sideways glance.

But when the stakes are really high, you need the best in your corner. JABB Gym, a spacious, sparkling clean boxing gym has made a name for itself by training professional fighters and Olympic hopefuls. And now the three partners — Tina Park, promoter Dominic Pesoli, and former world-ranked featherweight contender Mike Garcia — are offering intimidation-free boxing instruction for women.

Throw your first punch in a private lesson or ease into it with group training or an S&M (stick and move, silly) fighting class. If an all-out rumble is more your speed, gather the crew for a customized group session.

Sparring is optional, but if you decide to get in the ring there’s a screening room so you can thoroughly study your opponent’s tapes before facing off.

Which may finally teach you the most important fighting lesson of all: Choose your battles wisely.
