She performs 44 songs from all her 10 albums over three and half hours at each of her Eras Tour concerts, all while undergoing multiple costume changes.

And with dozens of shows to go, many are wondering how Taylor Swift is going to survive her world tour.

In Sydney last week, the Cruel Summer songstress played four shows back-to-back across four nights – a total of 10 hours and 30 minutes – without showing the slightest ounce of exhaustion.

The pop megastar said she knew what she was facing before she embarked on the tour, and came very well prepared.

‘I knew this tour was harder than anything I’d ever done before by a long shot,’ she told Time magazine last year.

How Taylor Swift performed four nights back-to-back for three and a half hours on her Eras Tour in Australia – and the one thing she gave up to do it

The pop powerhouse took extreme measures when it came to being in tip-top shape for the global tour.

She started training six months before it kicked off at a New York City-based gym called Dogpound – a ‘state-of-the-art’ facility ‘offering bespoke team, private training, lifestyle advice’.

She performed her entire setlist while running on a treadmill so that she would be ready to belt out her hits while dancing around the stage.

‘Every day I would run on the treadmill, singing the entire set list out loud,’ she told Time magazine.

‘Fast for fast songs, and a jog or a fast walk for slow songs.’

She also incorporated ‘strength, conditioning and weights’ into her fitness regime.

Three months before the tour kicked off in March 2023, Taylor also began working relentlessly with choreographer Mandy Moore to learn new dance moves.

‘Learning choreography is not my strong suit. I had three months of dance training, because I wanted to get it in my bones,’ she explained.

‘I wanted to be so over-rehearsed that I could be silly with the fans, and not lose my train of thought.’

Taylor also cut out alcohol, saying, ‘Doing that show with a hangover… I don’t want to know that world.’

But putting on her immense performances certainly takes a toll on Taylor.

She usually performs two or three shows in a row, followed by a bunch of days off before her next leg.

The Shake It Off hitmaker admitted she needs a full day to recover after finishing a run of shows, and she can ‘barely speak’ or walk afterwards.

‘I do not leave my bed except to get food and take it back to my bed and eat it there [for the first day after the shows],’ she revealed.

‘It’s a dream scenario. I can barely speak because I’ve been singing for three shows straight. Every time I take a step my feet go crunch, crunch, crunch from dancing in heels.’

No matter how sore she is, Taylor vowed that nothing will keep her from getting back on the stage when the next concert rolls around.

‘I know I’m going on that stage whether I’m sick, injured, heartbroken, uncomfortable, or stressed,’ she added.

‘That’s part of my identity as a human being now. If someone buys a ticket to my show, I’m going to play it unless we have some sort of force majeure.’

Taylor wrapped up the Australian leg of her Eras tour on Monday after playing to more than 600,000 fans across Melbourne and Sydney.

A record-breaking 96,000 fans attended each of her three nights in Melbourne, while Sydney attracted a further 83,000 Swifties at each of her four shows.

The pop sensation reportedly earned $25million per Sydney show.

Taylor also injected a whopping $145m into the NSW economy, as thousands of local and interstate fans flocked to the city for the must-see event of the year.

She is now in Singapore for three concerts on March 2, 3 and 4.
