This woman is using her baby as an actual dumbbell

Do you remember Chontel Williams, the mum-to-be who had taken the internet by storm with her ridiculously muscle-bound pregnant body?

Here's a reminder of Chontel (left) at almost 22 weeks:

It seems the next step in mum fitness is to incorporate your newborn into your exercise regime.

New mum Kristy transformed her post-baby body with the help of her...er baby.

Here's Kristy and her son, Tucker, hard at the squats...

A six-month-old Tucker is helping his mum with lunges...

And at seven months, he's also useful on arm day...

And leg day...

In fact, here is Tucker at six months old doing the plank. Hard. Core.
