Chowing down on a nutritious snack is a great way to get yourself amped for a workout. If your grub of choice is packing in the right mix of nutrients—protein and complex carbohydrates—it can provide you with the energy you need to sail through your go-to HIIT routine or yoga class like a pro.

But sometimes you just don't have the time to whip up a snack before you scoot your boot to the gym. Maybe that's because you're coming from work and were barely even able to throw on sneakers and leggings. Or maybe you're waking up at 4 A.M. for a five-mile run, and you'd rather sleep for five more minutes than throw together breakfast. If you aren't hungry, then you don't need to worry about eating. But if you are, having ready-to-go, store-bought snacks on hand is the easy solution for this situation.

Which snacks should you shop? Registered dietitians have seven great recommendations. Look for these the next time you're at the grocery store, and keep them in your fridge or gym bag at all times.
