This video of Imran Khan's fitness routine will scare Nawaz Sharif, says PTI

If you can't be the Prime Minister, might as well beat him... in the gym, of course.

Looks like political rivalry has taken a new form — a fight to the fittest!

First it was the Sindh Sports Minister who challenged his Punjab counterpart to 50 push-ups (though we all know how that flopped. Oops), now it has made its way to the big fish: PTI Chairman Imran Khan vs. Prime Minister Nawaz Sharif.

In a video upload on PTI Official Videos Facebook page, IK shows us how to #WorkWorkWork those abs, because he's gearing up to take over the Iron throne.

"Kaptaan's lifetime of training for this very decisive moment, it's been a long time coming! Be very afraid Nawaz Sharif," reads the caption.

What we're thinking: Where'd IK get those pink kicks from? They're quite cool, but those white socks are ancient, they have got to goooo.

Going by this workout vid, here's how the 64-year-old stays in shape:

1) Toe touch crunches

2) Bicycle crunches

3) Side-to-side obliques

4) Knee Ins

5) Basic crunches with knees up

Imran Khan may be dead set on becoming the next PM — cuz let's face it, he's been waiting for it like Leonardo DiCaprio was for his Academy Award — but we're not sure whether gym time = PM time.

Others have some things to say too.

Some people feel he's preparing for a position other than head of state:

Others are truly inspired:

Some call the video 'absurd':

Some people are anticipating fallout:

And some people know exactly what's going on in PM Nawaz Sharif's head:

Now we'd watch that.
