National MP Alfred Ngaro has delivered a good old-fashioned slap down after Police Minister Stuart Nash posted a video of himself pumping 45kg dumbbells at the Parliamentary gym.
"What (a couple) of MPs get up to in parliament at 11.00pm in between reading papers.
"5 sets of 12 reps with 45kg dumbbells (no heavier weights available in Parliamentary gym). Not bad for an old geezer," Nash bragged on Facebook.
As he finished his set and sat up to look at the camera, a red-faced Nash said "there you go, mate. Do that one."
