Try the Core Master
I’m hoping for a six-pack thanks to this, devised by trainer Dean Varga. It looks like a wobble board with a ball in the middle and handles. You do a range of exercises on it, from press-ups to planks. The instability means your core gets a harder, deeper workout. £149.95, thecoremaster.co.uk.

Fermented fizz, anyone?
Fermented drinks that help your microbiome are set to boom. Remedy Kombucha (from £1.99, from Tesco), a sweet tea full of live bacteria, tastes great without the usual sugary hit of fizzy drinks. And my favourite, Agua de Madre Kefir Water (£23.70 for six bottles, aguademadre.co.uk) is made with fermented cactus.
