Look, it’s hard to get all excited and ready to seize the day at the start of the new week – especially when it’s bloody cold.

Still, the cold didn’t stop one Sylvester Stallone from achieving his goals for the iconic Rocky movie.

UpROXX recently reported on the Oscar winner's exercise regime for the movie, and it sounds insane.

Stallone endured six days of working out, twice a day, alongside former Mr Olympia Franco Columbu (one of Schwarzenegger’s friends who featured in Pumping Iron). His diet included a glass of liquid aminos before breakfast.

Speaking about his workout, Stallone said: ‘I wanted to look like Tarzan – sleek, tight, almost catlike. I wanted to forget the bulk and go for well-developed muscles. I began a hardcore weight-lifting program, working out twice a day. When I made Rocky, I increased my exercise.’

Columbo continued to work with Stallone after the first Rocky movie, working through its sequels as well as the Rambo films. The workout routine they developed has been sustained by Stallone through the Rambo revival, Rocky Balboa, and in The Expendables movies.

‘I worked out a program that was right for him and then I led the way, constantly increasing weights and reps,’ Columbu explains. ‘I knew for sure that this would motivate him to try and keep up with me.

‘If I took a weight and did 12 reps, Sly would have to try and do at least seven. Then, next set, I would do 15 reps, so he would have to increase his reps to at least 10. By the end of our training he was doing curls with 70 lb dumbbells.’

According to Unilad, Stallone’s routine for Rocky III consisted of:
- 20 rounds of sparring in the ring
- 2 hours of weight lifting
- 2 miles of jogging
- lots of jump roping

This was six days a week, minimum.

Moreover, here’s Sylvester Stallone’s diet:
- Pre-breakfast: A glass of liquid aminos
- Breakfast: 3 egg whites, half yoke, Irish oatmeal, toasted pumpernickel bread, fresh papaya, few figs
- Lunch: Roasted summer squash, broiled skinless chicken, salad, figs or berries
- Dinner: Salad, broiled fish, high-fibre toasted bread; occasionally eats veal
