That back-to-school feeling is in the air, as summer begins to fade and the ‘second New Year’ (as productivity gurus and life coaches like to call it) starts in September.

Whether you’ve just returned from a long, relaxing holiday or you’ve eased up on exercise throughout the warmer months (and who can blame you with all those heatwaves), if you’re looking for some gym kit to kickstart your fitness routine, now’s the right time to stock up.

The autumn/winter collections are landing in-store and online, and there’s everything you need to update your workout wardrobe – from high-tech, long-lasting essentials to affordable basics.

Here are five activewear trends to help you get in gear for autumn…
