In an outtake video for Shake It Off Swift talks about her cheerleader training:
I’ve done a million basket tosses and I’ve never done one before the shoot. It’s really terrifying to know that you’re going to be thrown into the air, but they catch me so that’s good…I did a lot of running, which I hate! I’ve been running a lot [for a month] just to do this amount of cardio. These are the longest shoot days I’ve ever done.
