Trainor explained that it wasn’t so much about being ‘healthy’; it was to stay fit for her sons Riley, who turns four in February, and Barry, 17 months: ‘I mean, look at those kids. I’ve got to lift them up and chase them. I’m exhausted.’

How does she do it? Trainor shared that she doesn’t work out every day, saying ‘I’m not crazy’. Instead, ‘I try to go three times a week of lifting weights. I didn’t know lifting weights would change my life so much.’

As for cardio workouts, Trainor said: ‘I was like, dying, trying to run on the treadmill, and it made me swollen.’

Kotb replied: ‘Weights give you more energy later. I think when you run you get more adrenaline, but when you lift weights, you’re like, wow.’

‘And you’re dead the whole day,’ Trainor added. ‘I just saw I can be stronger, you know?’ before joking she can now lift her children ‘like a dumbbell’.
