So why seek the best water bottle for the gym? Drinking water at the gym serves two essential purposes: it keeps you hydrated and it shows people that you are serious about your workouts. If what you are drinking is water with some kind of supplement or flavouring in, so it's a funny colour, that's even better. A stylish and capacious water bottle helps make staying hydrated less of a chore. 

Obviously cyclists, runners and just people in general carry reusable water bottles around these days, but these are gym water bottles.

The bottle’s mouth is is wide enough to fit ice cubes and is designed for drip-free sipping, plus its exterior is designed to be condensation-free so it won’t get your gym bag wet.

You need only shake the bottle to sync your drinking data with the Bellabeat app, which shows you trends and progress. The bottle might help you stay on the straight and narrow when it comes to sipping frequently, but the technology comes at a price… specifically, 80 quid.

Best water bottles: Wilko's basic

5. Wilko water bottle

Cheap and cheerful option

Reasons to buy
+Basic bottle that’s cheaper than a coffee+Choice of colours
Reasons to avoid
-Basic AF

• Buy direct from Wilko for £3

If you take the view that whatever gym water bottle you buy is going to get left behind eventually, an ultra-cheap option might seem sensible. Cheap and reasonably cheerful retailer Wilko has some great options under £5. This 800ml water bottle has a pleasing curved shape and comes in a choice of colours. The 'interesting' screw-top might start to get on your nerves after a while, but it's better than having to buy a bottle of water for £3 from the gym's vending machines, or fishing someone else's used one out of the bin and refilling it from the gym's skanky water tap. Not that we have done that. The bottle is made of impact-resistant Tritan and is dishwasher safe, but not freezer safe.
