What Are The Worst Pre-Workout Snacks?
Generally, all the foods that can somehow disrupt your performance during exercise and cause digestive problems are a bad choice before a workout.
Here are the 5 worst pre-workout snacks that you should not try before a workout:
1. Greasy Foods
Eating fried foods is super tasty, but they pack a lot of bad fats and calories, which isn’t great for your bodybuilding goals. These munchies take their sweet time breaking down and can cause bad digestion. When you chow down on fried grub before exercising, your body’s too busy trying to digest instead of pumping up those muscles.
Say you grab some fried chicken, chips, or donuts – those things are stuffed with trans fats and oils that’ll make you feel zonked and puffy. Snacking on them pre-workout might make you drag yourself around or, worse, make you want to hurl mid-crunches. Moreover, they jack up your blood sugar to let it plummet soon after, leaving you wiped out and all over the place.
2. Sweet Munchies
Eating sweet stuff like candy, cookies, or sweetened cereals before exercising might perk you up fast, but it won’t last. Highly refined sugar treats can shoot your blood sugar up quickly and then drop it, making you feel drained and feeble. That’s the worst thing when you’re trying to get your sweat on.
Moreover, these sugary bites don’t pack the nutrients you need to keep going when you’re working out. They give you a brief energy pop but don’t power you up for the long haul. Better to go for a snack that mixes some protein, good fats, and complex carbs. This will keep your power steady and your muscles ready to go.
3. Dairy Goodies
Stuff like milk, cheese, and yogurt is packed with protein and calcium, but they aren’t your pals when it’s time to hit the gym. Dairy tends to mess with some folks’ stomachs, which can lead to feeling bloated, getting cramps, or even getting hit with diarrhea while you’re trying to work out. That kind of trouble can throw you off your game.
Lactose can be a real pain for some, so if dairy tends to upset your belly, steer clear of it before you exercise. If you’re cool with dairy, plan to snack on it maybe two or three hours before exercising so you give your body plenty of time to handle it.
4. Zesty Grub
You should steer clear of spicy food before hitting the gym. Things like hot peppers and zesty sauces might mess with your tummy, causing nasty stuff like heartburn, acid reflux, or even tummy aches when you’re trying to exercise. This can get in the way of your exercise game and throw you off your groove.
Munching on fiery snacks might crank up your stomach acid, too, making you feel queasy or sick while you’re working out. Best to munch on that spicy grub after you’re done with your workout so your body isn’t in the middle of digesting and pushing you through a sweat session.

5. Caffeinated Beverages
Loads of folks grab a coffee or gulp down an energy drink for a quick zap of stamina before hitting the gym. Sure, caffeine sharpens your focus and makes you more alert, but overdoing it pre-exercise might mess things up. Caffeine’s a stimulant. So, it pumps up your heartbeat and could make you thirsty big time if you chug too much.
During a workout, you sweat buckets to keep cool, but if you’re starting all parched from too much caffeine, cooling off gets tough. This parched feeling can lead to getting worn out, muscles freaking out with cramps, and you not doing your best. If you’re going to have caffeine before pumping iron, don’t forget to knock back loads of water to keep your hydration level up.
