Napier MP Stuart Nash has been caught up in a comedic flexing contest after posting a video of himself pumping iron at the gym.
The Police Minister, donning a grey singlet with his biceps bulging, posted a video of himself pumping 45kg dumbbells at the Parliamentary gym late Tuesday night.
"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 posted 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".
