Let's make one thing clear - jumping up and down in your living room isn't going to make look like Chris Hemsworth. Nor Hugh Jackman. We'd all be at home traumatising the cat if it did.
But high intensity interval training can shift that stubborn wheel of winter insulation from your midriff and help you feel a whole lot healthier.
These excellent pop culture themed workouts from fitness trainer Nelia Rey don't require any costly equipment or access to a sweat-saturated gym. Each routine has a range of bodyweight exercises, with the option to up the difficulty by increasing the number of repetitions.
