Well, one look at Goulding's Instagram account answers that question. The "On My Mind" singer's page is jam-packed with videos of herself working out, and these exercises look hard. Her most recent? A clip showing her doing what can only be described as one of the most challenging ab moves we've ever seen.
In the clip, Goulding lays on a decline bench, a weighted barbell held directly above her head. The singer manages to complete quite a few sit-ups, and we're totally impressed. "Good for the abs..." she cheekily captioned the black-and-white vid. Um, yeah. We know what exercise we'll be trying next time we hit the gym.
