Fuel Your Workouts: Why I Never Skip Carbs Before Lifting

A few years back I tried training fasted because a guy at my gym swore by it. Rolled out of bed, black coffee, straight into leg day. By my third set of squats the bar felt like it had doubled in weight, my head went foggy, and I cut the session short pretending I had somewhere to be. I didn't. I went home and ate toast and felt sorry for myself.

That was the last time I ever lifted on an empty tank. These days I treat pre-workout carbs the same way I treat charging my phone: non-negotiable, because I know exactly what happens when I don't.

Your muscles run on carbs, whether you like it or not

Here's the short version without the biochemistry lecture. When you lift weights, your muscles pull energy from glycogen, which is just the storage form of carbohydrate sitting in your muscles. Heavy sets burn through it fast. Fat is a fine fuel for walking the dog or sitting at a desk, but the moment you ask your body for hard, explosive effort, it reaches for carbs first. Every time.

So when you train with your glycogen half empty, you're basically asking your body to sprint while it's rationing fuel. It'll do it, grudgingly, but everything feels heavier than it should and the last few reps you're capable of just never show up.

What actually changed when I started fuelling properly

The bar moves better. Same weight, same program, but sets that used to grind now feel crisp. I'm not magically stronger - the strength was always there, I just finally had the fuel to express it. An extra rep or two on your top sets, week after week, adds up to real progress.

I don't fade halfway through. My old sessions had a very clear cliff around the 40-minute mark where everything after felt like admin. Eating carbs beforehand flattened that cliff. The last exercise of the day gets the same effort as the first now.

My head stays in it. This one surprised me. Your brain runs on glucose too, and it turns out "foggy and irritable" is not the ideal state for squatting heavy. Fuelled sessions feel focused. I'm thinking about my form instead of thinking about food.

Training stopped feeling like a chore. Honestly this is the biggest one. Good sessions make you want to come back. Terrible, flat, grindy sessions make the couch very persuasive. Eating carbs before training made most of my sessions good ones, and consistency did the rest.

When I eat them

Nothing fancy. If I'm training in the evening, my normal lunch a few hours out does most of the work - and being Filipino, there was never any danger of that lunch not including rice. Then about 45 minutes to an hour before the gym I'll have something small and easy to digest, just to top up.

Morning sessions are trickier because nobody wants a big meal at 5:30am. My move is something light the second I wake up - a banana or a couple of rice cakes with honey - then coffee, then train about 30 to 40 minutes later. Light enough that it doesn't sit in my stomach, enough fuel that the session doesn't suffer.

What I actually eat (all from the local Woolies)

• Bananas - the undefeated pre-workout snack. Cheap, zero prep, sits well.
• Rice cakes with honey - my morning go-to. Digests fast, feels like nothing in your stomach.
• White rice - the foundation of my bigger pre-training meals. Rice with anything works.
• Oats - great if you've got 90 minutes or more before training. A bowl with a banana sliced in is a proper pre-workout.
• Toast with jam or honey - dead simple and it works.
• Weet-Bix with milk - about as Australian as it gets, and quietly a great pre-gym feed.

Notice there's nothing exotic on that list. No supplements, nothing from a specialty store. The best pre-workout carbs have been sitting in the supermarket the whole time costing a few dollars.

A few things I learned the hard way

Match the size to the time. Big meal, leave two to three hours. Small snack, 30 to 60 minutes is plenty. Eat a huge feed 20 minutes before squats exactly once and you'll never need this advice again.

Keep the fat low right before training. Fat slows everything down, which is great for staying full at dinner and terrible when you want that energy available in half an hour. Save the peanut butter for after.

Don't experiment on leg day. Try new pre-workout foods before an easy session, not before the hardest one of your week.

Carbs are not the enemy, even when cutting. I eat carbs before training every single day of a fat loss phase - I just budget for them. If you're worried about that side of things, I wrote about how fat loss actually works, and spoiler: it was never about the carbs.

The takeaway

You don't need a new program, a new pre-workout powder, or more motivation. Sometimes you just need fuel. Eat some carbs before you lift - a banana, some rice, toast with honey, whatever's around - and pay attention to how the session feels. I'd bet money you lift better, last longer and enjoy it more.
