There's a new English language Jihad-ist magazine out online and it's even got a section for the fundamentalist fanatic who needs to tone up a little before the next holy war.
Oh... and they did example photos!!!
I promise, hand on heart I haven't made these up or doctored them.
Check for yourself HERE on page 22 (as long as you're alright with possibly being put on a government watchlist)
"Building your legs is the most important part of your body to prepare for Jihad, and if you think Jihad is anything but long walks, jogging and running then you are quite mistaken. On top of that you’re going to be carrying weapons and equipment!"
