Outlander actor Sam Heughan has wowed fans after showing off his muscles in a fitness Instagram post.
The 41-year-old star is shared a video about the Munro Step Challenge he has undertaken to raise awareness for charity Blood Cancer UK.
Heughan, from Dumfries, took to Instagram to encourage fans to take part writing: "One of my favourite challenges throughout the year.
"It’s so easy to participate, good for your health (actually amazing for fat burn, increased endorphins and personal mindfulness) AND helps us raise awareness for Blood Cancer awareness month and @bloodcancer_uk."
Sam first began completing the challenge in 2015.
Participants pick up one of the famous trails the world has to offer and can virtually climb the walk by keeping count of your steps either on a treadmill or on walks around your local area - or if you are lucky enough, perhaps the real trail itself.
Fans applauded the actor for raising funds and awareness for a cause close to their heart.
One wrote: "Thank you for doing this Sam. Lost my Mom to Leukaemia two years ago, so this is close to my heart."
Another agreed: "This is awesome! My uncle was diagnosed 4 months ago with blood cancer. He's been going through treatments and he's fighting hard...thanks for raising the awareness."
A third said: "One of my favourite charities it’s very close to my heart. A success and healing outcome and I hope this for every one. Go Peakers’!!"
But some other cheeky social media users praised Sam for his muscular physique in the video showing the Hollywood Hills.
One fan declared in the comments: "Here, ladies and gentlemen, is the reason for the wildfires in Cali!"
Another agreed writing: "SOOOO BEAUTIFUL"
A third was in unison: "THIS is your next BOND. Articulate. Witty. Sexy. = Deadly Combination."
