Now that Jamie Chung has had some time to let her engagement
sink in, she's ready to start planning her nuptials – and talk about fiancé Bryan Greenberg's proposal.
"It was a total surprise!" Chung, 30, told PEOPLE at Reebok's ZQuick shoe launch in New York on Wednesday. Greenberg, 35, popped the question in Chung's native San Francisco over the holidays.
The bride-to-be and her beau are looking forward to the months leading up to the wedding. "We just want to enjoy the year of being engaged," she says.
As for a date? "Oh, I don't know ... maybe fall 2015," Chung says, noting she's eager to get planning. "I think it really is stress-induced in terms of planning a wedding, but we've kind of initiated the conversation. I think the sooner you start, the less stressed out you're going to be."
Chung, who stars in Alfonso Cuarón's upcoming series Believe
, is known for her sleek physique and enjoys an active lifestyle – so much so she plans on integrating that into her big day.
"We love working out. We love the outdoors. So we want to incorporate that – maybe make it a weekend and have all the guests go on a hike. Or there's a crazy obstacle course at this one location," she says. "We literally have to do something every day in terms of something physical."
And while Chung may not have her location picked out yet, she has some ideas.
"We want to do it somewhere in the woods. We're looking at some locations in California – we just don't know where it's going to be yet. It’s going to be a fun wedding," she says.
