Ciara Madden — aka @ciaralondon on Instagram — is one of the UK's best personal trainers (she's worked with Maya Jama and Neelam Gill), and she's offering 12pm daily workouts via IG for a small fee. (£15 for a monthly subscription to six live workouts a week, one stretch session on your rest day, two live tutorials a week, and one weekly live health and nutrition Q&A.) Her butt-and-leg-themed workout — a class that utilises resistance bands for maximum impact to burn out and define the glutes — really pulls in the crowds.
