It's never too late to get into fitness and one elderly woman from Tianjin, China, is living proof of this.

Fondly known as Grandma Bai, the 79-year-old has gone viral on Chinese social media for her intense exercise regimes. 

She trains five days a week from Monday to Friday, according to Chinese media Xiaoxiang Morning News on Monday (Sept 16).

"Each fitness class lasts for an hour, but I need to warm up one to one-and-a-half hours in advance. Otherwise, I can't keep up with my coach's progress," she shared with the publication. 

Some types of exercises she does are weightlifting and pilates. 

And when it comes to high-intensity fitness programmes, Grandma Bai confidently said: "There is no pressure and it's easy to do." 

Got into fitness because of poor health

Grandma Bai had never always been this active and only started after she turned 60, adding that she's been into fitness for 19 years. 

For the earlier part of her life, she worked in the finance industry and was so focused on her career that she neglected her health. 

Because of this, she needed to go for three surgeries.
