Outlander's Sam Heughan flexed his bulging muscles today as he shared a fitness work out with his fans.

The Scots actor has always been known to keep in shape and today as he posted a sweaty snap, fans really couldn't get enough - so much so one asked the star to marry her.

Taking to Instagram, 41-year-old Sam posed in a tight black Nike vest top and a pair of The North Face shorts while clutching a kettle bell surrounded by other gym equipment.

He captioned the picture: "Sweaty weekend @mypeakchallenge garage gym workout done!"

He then gave a full run down of his work out which included, burpees, dead lifts and Russian twists.

He then added: "Thanks to @kettlebellkings for the sweet gear. (Can I put this down now?)"

And fans were left extremely hot under the collar, prompting a marriage proposal and one even dropped the 'L bomb'.

One wrote: "MARRY ME."
