Revealing the 5 SECRETS that enabled Taylor Swift to perform 44 songs four nights in a row for three and a half hours during her Eras Tour- and the one thing she gave up that made millions of fans startled and REGRETFUL…

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.
