Unfortunately, I can't seem to find the name of this male model anywhere!
His picture is featured alongside a few articles, but he's not credited, which is a shame as he's obviously quite popular. His picture's mostly been used to show the effects of muscle improvement programs!
How to trace images of unknown male models
Sorry I couldn't be of more help, but in future if you'd like to source an image, or similar images, a quick way is to use Google reverse search.
Just right click on the image you want to source, then click 'Search Google for this image'. If the model or whatever you're searching for can be found, you can usually trust Google to find it.
If not, you can find similar images that may show you something new that matches your taste!
