Kayla Itsines's arms workout for new mums

When you have a newborn, you have about as much chance of getting to the gym as the newest member of your family does.

But if you feel like staying active and you find a spare moment at home, #TeamCoach's fitness trainer Kayla Itsines is sharing some simple workouts for new mothers in a new video series for ninemsn Coach.

"As a new mum you don't have a lot of time, so every little bit counts," Kayla explains.

"It's about giving it a go, getting your body moving and being active when you can."

In the first video above, Kayla runs through step-by-step instructions for an arms workout you can do at home with easy-to-find equipment, while bub is napping.
