Best Snacks Before a Workout
You have your kit on, your playlist ready — and then it hits you: should you eat something first? Train on an empty stomach and you risk running out of fuel halfway through. Eat the wrong thing and you feel heavy and sluggish. The right pre workout snack sits perfectly in between: it tops up your energy without weighing you down.
Whether you are heading to the gym, going for a run, or making a class after work, what you eat beforehand makes a real difference. In this guide we break down what to eat, when to eat it, and the easiest pre-workout snacks that actually deliver.
Why What You Eat Before Training Matters
Your body's main fuel for exercise is carbohydrate, stored in your muscles as glycogen. When those stores are low — first thing in the morning, or hours after your last meal — a workout can feel like wading through treacle. A small, well-chosen snack tops up that fuel so you can train harder and stay focused for longer.
Just as important: the right snack helps you avoid a mid-session energy crash and stops hunger from becoming a distraction.
What Makes a Good Pre-Workout Snack
A great pre-workout snack follows three simple rules. First, easy-to-digest carbohydrate as the base — carbs are the quickest energy source, so fruit, oats or wholegrains work well. Second, a little protein to support your muscles and make the energy release feel steadier. Third, go easy on fat and fibre right before training, because both digest slowly and a large amount close to a workout can leave you feeling heavy.
Timing: How Long Before a Workout to Eat
Timing changes what you should reach for. Use this as a simple guide:
| Time before workout | What to eat |
|---|---|
| 2–3 hours | A balanced small meal — carbs, protein and a little fat |
| 1–2 hours | A light snack, mostly carbs with a little protein |
| 30–60 minutes | Something small and quick to digest, like a banana or a protein bar |
The closer to your workout, the smaller and simpler the snack should be. Everyone is a little different, so experiment to find what feels best.
The 6 Best Snacks Before a Workout
Here are our favourite pre-workout snacks — chosen for how quickly they fuel you, how easy they are to digest, and how little prep they need.
1. A Banana
Almost pure easy-to-digest carbohydrate, naturally portable, zero prep. Ideal for the final 30–60 minutes before training.
2. A Mycelium Protein Bar
The easiest grab-and-go fuel. FungoFit bars are plant-based with 20g protein and no added sugar — steady energy, no crash.
3. Greek Yogurt & Berries
A light, balanced option for 1–2 hours out. A little protein from the yogurt, quick carbs from the berries.
4. A Small Bowl of Oats
Slow-release carbohydrate that keeps energy steady — great for an early workout with a couple of hours to spare.
5. Rice Cakes with Honey
Light, crisp and very easy to digest. A thin drizzle of honey adds fast-acting carbohydrate for a quick lift.
6. Apple Slices & Nut Butter
Quick carbs from the fruit plus a touch of protein. Keep the nut butter to a thin spread this close to training.
Why Functional Mushrooms Belong in Your Pre-Workout
Most pre-workout products lean on caffeine and sugar for a fast hit — followed, all too often, by a crash mid-session. Functional mushrooms take a different approach. Cordyceps, in particular, has been used for centuries to support stamina and oxygen uptake, working with your body's own energy systems rather than overriding them.
That is the thinking behind FungoFit bars: a meaningful dose of functional mushroom alongside 20g of plant-based protein, so your pre-workout fuel is steady and clean — no jitters, no crash.
Fuel Your Session the Smart Way
The FungoFit Crunchy Almond & Cordyceps bar is the easy pre-workout snack — plant protein and functional mushrooms in one.
Your Pre-Workout Snack Blueprint
Even the best snack falls flat at the wrong time. Here is a simple way to plan it around your session:
2–3 Hours Before
Have a balanced small meal — carbs, protein and a little fat. Think oats with yogurt and fruit, or a wholegrain wrap.
1–2 Hours Before
Go lighter: mostly carbs with a little protein. Greek yogurt with berries, or apple slices with a thin layer of nut butter.
30–60 Minutes Before
Keep it small and quick to digest. A banana, rice cakes with honey, or a FungoFit bar are all ideal here.
Don't Forget to Hydrate
Even mild dehydration makes training feel harder. Drink water in the hour or two before you start — especially with drier snacks.
What to Avoid Before a Workout
Knowing what not to eat is just as useful. Close to a session, watch out for these:
- Very fatty foods — they digest slowly and can leave you feeling heavy mid-workout.
- Very high-fibre meals — great for everyday health, but better saved for after training.
- Large portions — a full stomach and exercise rarely mix well.
- Sugary snacks with no protein — a quick spike followed by a crash partway through.
The Bottom Line
The best pre workout snacks are carbohydrate-led, light on fat and fibre, and timed to how long you have before training. The closer to your session, the smaller and simpler the snack — a banana or a protein bar is ideal for that final hour.
Get this right and the difference is obvious: steadier energy, sharper focus and a session that feels strong from start to finish. For recovery afterwards, see our companion guide on the best snacks after a workout, and for more everyday ideas, our top 10 healthy snack ideas.
