Bear Grylls presents Week 3 of his 40 day military fitness challenge to get Brits into shape

BACK in the pub?

Make sure your fitness doesn’t slip by joining Bear Grylls’ Be Military Fit programme.

Over the last few weeks he’s been sharing a series of exclusive videos for Sun readers – and here he unveils the third, as part of a 40 day challenge.

He said: “Training outside is going to be better for your physical and mental health than being stuck indoors in a gym on your own.

“You get the fresh air, the vitamin D and that little bit of grit.”
