Whether you’re heading off to spin class, boot camp, or any other exercise, it’s always important to hydrate so you can stay energized and have your best workout. But you don’t want to grab just anything for hydration purposes.
Electrolyte-loaded athletic drinks, for example, can be a source of unnecessary calories, so “drinking water is usually fine until you’re exercising for more than one hour,” Jackie Newgent, RD, author of The Big Green Cookbook, tells Health.
But if you are working out harder and longer, feel free to go for regular Gatorade-type drinks (and their calories), which can give you a beneficial replenishment boost. But worry not if you like a little flavor during your fitness: There are now lower-cal sports drinks available, adds Newgent, so look out for ’em in your grocery aisles.
