Getting a washboard stomach like Irina Shayk takes work – the hard-core spin cycle class on a Sunday kind of work.
Posting a picture on Instagram of her killer figure in a sports bra, the model said, 'that's how we roll Sunday nite# soulcycle class.'
Soul Cycle is a cult full body indoor cycling class in America which incorporates weights and core exercises, combining fat burning with strength training.
No wonder she's proud!
The class keeps attendees pumped by throwing in some high-energy music and inspirational coaching, so there's no excuse for slacking off. Lady Gaga and Katie Holmes are also fans.
If you fancy trying out Irina's workout in the UK, head to a BodyBoom! Class in London for spin cycling incorporated with weight training, boommybody.com, or Virgin Active's V-Cycle class (available nationally), virginactive.co.uk
