Back in the day, you busted windmills and elbow spins without even breaking a sweat. (Represent.)

Now, your chiropractor strongly urges against it.

But whether you’re old school or new, b-boys (and b-girls) should lace up their Adidas: Double Dutch opens today in the Mission.

Step inside and enter New York City’s golden age of hip-hop and punk rock. Lit by neon chandeliers, the Beat Street scene is still dark enough for your baddest moves (that’s bad bad, as in not good, as in the Robot). Hardcore crews can try to out-Worm one another in the break-dancing circle next to the DJ booth while too-cool and the gang take five in the garden in back.

Avoid injury altogether by kicking it on the black leather couches with gin and juice in hand.

Or, better yet, just schedule your back adjustment in advance.

Double Dutch, 3192 16th Street, between Valencia and Guerrero Streets.
