Magistrate Donald MacKenzie said Tippet was a poor role model, and should've bulked up in a legal way by eating 'honey and banana sandwiches'.

'Particularly with young men and seeing they can have the body that you have and thinking they can have a body like you by using steroids,' Mr MacKenzie said.

Mr MacKenzie said Tippet was 'idiotic' for using steroids when he had a serious heart issue.

Tippet charges up to $150 for an eight-week 'body bulking' program which he advertises through his Instagram account.
