This energetic toddler put the AB in baby as she used her bouncing chair to perform some sit-ups.
Adorable Aislinn Kerr was watching the TV with sister Amilia at home in Barrow-in-Furness, Cumbria, when she started doing the exercise on February 2.
As her twin placidly lies back in the rocker, Aislinn uses the momentum to spring her torso off the seat and throwing her hands up in front of her.
Reminiscent of the classic abdominal exercise normally seen in gyms, the effervescent infant continues unabashed much to the delight of dad Anthony.
Anthony said: “I found it really funny that Aislinn appeared to be doing some manic situps.
“Her and Amilia love sitting in front of the TV and will stay there for half an hour or longer.
“In that time Aislinn just carries on doing this until she runs out of steam.
“The pair of them are mad but as long as it keeps them happy I don’t mind.”
