Chris Pratt has stripped off to flaunt his bulging biceps and chiselled chest in his first-ever Super Bowl television commercial for Michelob's new low-calorie beer.

The 'Jurassic World' star has set pulses racing in the advert, which has been released ahead of the NFL final this Sunday (04.02.18), as he is seen peeling off his kit and showed off his gym gains as part of a small-screen collaboration with the brand for their new ULTRA range.

Taking to his Instagram account, Chris said: ''These days, I'm trying to stay in top shape for work. So when I see a beer I can't help but squint my eyes and imagine a treadmill - Specifically how long I'll have to be on that treadmill to burn off the beer. Michelob ULTRA has only 95 calories and 2.6 grams of carbs SO ... I can run that off very easily. Probably in like 10 seconds? (I run 85 mph) Which really makes you wonder why I'm not playing in the Super Bowl instead of just doing a commercial that will air during the Super Bowl. So anyways, Michelob ULTRA doesn't throw off my workout routine. And it tastes great. So ... That's what I call a win win. Check it out before it airs on Sunday.''

In the one-minute advert, the 38-year-old actor can be seen working up a sweat in the gym, picking up the pace with his trainer and slaving away with heavy dumbbells, before relaxing with a pint of Michelob ULTRA around the table with his friends.

It then becomes apparent that the hunky actor is in training for the television advert and wants to be in the ''best shape of his life for the big role'', but he's not worried about guzzling down the alcohol beverage in the evening because it's low calorie.

And the temperature soars when Chris - who recently split from his wife Anna Faris - takes off his camo-coloured tee to flash his ripped body as he chats away to himself.
