‘The Mountain’ Hafthor Bjornsson has given fans an update on his incredible  weight loss by sharing an image of his trim new physique on Instagram.

The 2018 World’s Strongest Man referenced a “killer morning session” in the gym and said his weight had  shed just under 40lb of bulk.

Not that we’d say it to his face, but Bjornsson looks far slimmer around the midriff than he was earlier this year.

It’s clear from his fighting stance that he’s losing weight in preparation for his boxing bout against fierce rival Eddie Hall, scheduled for September 2021.
