Ashley's intense workout included kettlebell squats, side weighted side lunges and back lunges, all performed without a wobble.
The presenter has always been into fitness. Prior to joining The Pussycat Dolls she was a professional dancer and choreographer and she told Coach Magazine: " Some people don’t think of dancers as athletes but that’s garbage. All-day sessions in the studio are hardcore total-body workouts."
"I did ballet, tap, modern and lyrical – all different styles that tested my fitness and worked my muscles in different ways," she said.

She also previously said: "I love exercise; it’s not only for my physical health but it’s for my mental health so it’s very important to me."
It's not just dancing that Ashley loves. As seen in her video, weightlifting is another favourite activity of hers. "Lifting gets my heart rate up and makes me look amazing, but more importantly it makes me feel strong," she told Coach.
She's sung the praises of spinning, kick boxing and yoga too.
Of yoga, she told Coach: "Not only is it good for mobility and injury prevention, it de-stresses me too. You need to have a balance of hardcore stuff and things that centre you, plus your body needs time to recover after doing heavy deadlifts and squats."
