THE MUST-HAVE

i Fitbit Flex 2

£69.99, www.fitbit.com

Fitness trackers are 10 a penny, but this reliable model from Fitbit covers the basics without being too bulky or bogged down in technical detail. Attach to your wrist and the waterproof band will count your steps and keep a tally of any fitness goals as you stride. Link it to a smartphone, double tap the band and wait as lights appear. Each solid light represents a quarter of the day’s fitness targets completed. It’ll also give you a nudge if you’ve been inactive for too long, but you can turn this feature off!
