NEW YORK (

TheStreet

) -- One of the most important ingredients to making a business partnership work is communication, says Jen Whinnen, co-owner of the

Yoga Collective

and owner of

Three Sisters Yoga

.

Owning a business on your own means "you're in charge, which is a blessing and a curse, but with a partner that takes some of that pressure off, which is awesome," Whinnen says.

Whinnen started Three Sisters Yoga in New York City in 2009 to train and certify yoga instructors. This past May Whinnen and a partner opened The Yoga Collective to offer new instructors a place to practice their own teaching.

Partners need to be honest and upfront with each other, she says.

"If something is bothering you, say something right away and keep it all out in the open," she says. "If you sit on it, it's going to explode."
