Quick Answer

Fruit bars can be a good pre-workout snack for low-to-moderate intensity exercise, especially when you need quick, easily digestible carbs. However, they may not provide enough sustained energy or protein for longer or more intense workouts. The key is matching the bar's ingredients to your activity type and timing.

When Fruit Bars Work Best as a Pre-Workout Snack

Fruit bars shine when you need a light, fast source of energy about 30–60 minutes before exercise. Because they're made from whole fruit with no added sugars or preservatives, they provide natural carbohydrates that your body can use quickly. This makes them ideal for morning walks, yoga, light jogging, or a casual gym session where you don't want a heavy stomach.

The simplicity of ingredients—just fruit and nothing else—means there's little risk of digestive upset. For example, That's It fruit bars contain only apples and cherries or mangoes with probiotics, so you get fiber and natural sugars without artificial additives. If your workout is under 45 minutes and moderate in intensity, a single fruit bar can give you the boost you need without weighing you down.

When Fruit Bars Might Not Be Enough

For longer endurance activities like running over 10 miles, high-intensity interval training, or heavy weightlifting, fruit bars alone may leave you short on energy. They are low in protein and fat, which help sustain blood sugar levels and support muscle recovery. If you rely solely on a fruit bar before a demanding workout, you might feel a quick spike in energy followed by a crash.

In those cases, consider pairing a fruit bar with a small source of protein or healthy fat—like a handful of almonds or a spoonful of nut butter. This combination provides more balanced fuel and helps maintain steady energy throughout your session. Alternatively, choose a pre-workout snack that includes protein and complex carbs if your workout is intense or lasts longer than an hour.

How to Choose the Right Fruit Bar for Your Workout

Look for bars with simple, whole-food ingredients and no added sugars. That's It fruit bars fit this criteria perfectly, with options like Apple + Cherry or Mango Probiotic. The probiotic version adds live cultures that may support gut health, which can be beneficial for overall digestion and comfort during exercise.

Check the calorie content—most That's It bars are around 100 calories per bar, which is appropriate for a light snack. If you need more energy, you can eat two bars or combine one with another small snack. Also consider the variety pack, which includes Apple + Fig, Apple + Blueberry, and Apple + Strawberry, giving you flavor variety and a consistent nutritional profile.

Pre-Workout Snack Diagnosis

  • Symptom: You feel sluggish or hungry before a workout, or you experience an energy crash mid-session. Your pre-workout snack may lack the right balance of carbs, protein, or timing.
  • Likely Cause: Eating too close to exercise, choosing a snack high in simple sugars without protein or fat, or skipping a snack altogether. Fruit bars provide quick carbs but little protein or fat, which may not sustain longer efforts.
  • Corrective Action: For workouts under 45 minutes, eat one fruit bar 30–60 minutes before. For longer or intense sessions, pair a fruit bar with a protein source like nuts or yogurt. Match the snack to your workout duration and intensity for steady energy.
  • Stop or Choose Another Option: If your workout exceeds 60 minutes or involves heavy strength training, consider a snack with more protein and complex carbs, such as a protein bar or a banana with peanut butter. Fruit bars alone may not be sufficient for demanding exercise—adjust your snack accordingly.
