Actress Kate Hudson says that she teans up with her children to improve her workout routine.

While exercising, the actress involves her two sons - 10-year-old Ryder from her marriage to ex-husband Chris Robinson and her three-year-old Bing with her long-term boyfriend Matt Bellamy, reports femalefirst.co.uk.

"I love exercising with my kids! I'll walk around for a couple of hours with Bing on my back - that's a workout," she was quoted as saying.

"And I've been kick-boxing with Ryder. I can do squats with him on my back. He's 10 now, so he's starting to get a little heavy ... but I can still do it. I'll probably get another year out of him, then Bing's next.

"I've also bench pressed Bing before now. The kids love it - and after about five lifts, you're exhausted,` added Hudson.
