One of them is by a pool.

The organizers behind Pop Up Yoga at Fort Canning last month have come up with two more affordable yoga sessions this month. Like the previous Fort Canning event, they are all about practising in a relaxing and social atmosphere, minus the competitive vibe you might sometimes get at a trendy studio.

At POP UP YOGA (Pool Party Edition @ Orchard), the one-hour 30-min yoga flow session is held on a "secret" rooftop at Orchard Road on Jun 18 from 8:30am-12:30pm. There's a chance to chill by the pool and refuel at a bring-your-own-food potluck party post class. And in conjunction with International Yoga Day, POP UP YOGA x International Yoga Day (Jun 21, 6:30pm) is a free sunset session at Marina Bay Sands' boardwalk. The classes are open to participants of all levels.

Registration is required for both events, and you have to bring your own yoga mat and bottled water. For more information, follow Urban Yogis on Facebook.
