Cardio workouts have long been hailed as one of the best way to boost your heart health, fitness levels and more - so much so, that global popstar Taylor Swift has recently revealed that she trained for her entire Eras tour while running on a treadmill.
The 33-year-old star confirmed that to prepare for the gigs, which saw her on stage for over three hours each night performing 40 sounds in 16 different costumes, she trained for six months.
