Charlotte Kalla is one of Sweden's most successful cross-country skiers of all time.

The basis for the many medals and podium finishes is a well-known willingness to train, but exactly how much Kalla trains she has been secretive about.

Now she chooses to reveal to Expressen exactly what the training load during a pre-season week looks like.

- I have never shown this before, says Charlotte Kalla to the newspaper.

"Lying down on the floor in the gym"

Six days out of seven possible days are training for the 33-year-old and 22.5 hours in total will be during this week at the end of May 2020. The sessions are divided into effort levels where A1 (60-75% of maximum heart rate) is the most affordable.

The A3 + pass (90% of maximum heart rate) saves Kalla until Sunday after a rest day on Saturday.

- It's the toughest workout this week.

It usually ends with Charlotte lying on the floor in the gym and panting quite well, says Kalla's coach Magnus Ingesson to Expressen and continues:

- Each set is two minutes including rest.

So she stakes 200 meters in 40-45 seconds.

Then she goes straight to ten burpees, for example.

When she is done with them, the clock is at 1.07 and then she gets 53 seconds of rest.

We drive like that eight times before she gets a longer rest of 2-3 minutes.

It's a war.

And this is the war we want.
