"Our business remained strong in the second quarter as we continue to bring new guests into the brand through our stores and multiple e-commerce platforms," Calvin McDonald, chief executive officer, said about the brand's continued robust performance in the mainland market.

McDonald attributed the growth to Lululemon's "innovative product offerings and omnichannel operating model".

"We are acquiring guests through our unique made-to-feel positioning, which comes to life through our commitment to movement and community, all of which supports the Healthy China 2030 initiative," McDonald added.

During the second quarter, Lululemon's Summer Sweat Games expanded to more than 70 stores across nearly 40 cities, engaging about 10,000 participants.

Looking ahead to the third quarter, Lululemon plans to leverage World Mental Health Day in October with events across several cities in China.

"We remain excited about the potential for Lululemon on the Chinese mainland," McDonald said. "Our business remains strong, and we believe several factors will continue to benefit us."

During the post-results earnings call, McDonald said Lululemon's footprint in the Chinese market is still relatively small, with 132 stores as of the end of the quarter.

Sportswear brands have geared up for more collaborations with competitions and training to enhance their community engagement.

Asia Crossfit Championship, a leading fitness event, has joined hands with Adidas to collaborate on events, user community, training, court channels and member services.

The Asia Crossfit Championship will be held in Shanghai in the fourth quarter.
