“I just didn’t have it today.”
As coaches, we hear this all the time. Maybe you’ve said it yourself after a workout that felt harder than it should have. The weights felt heavier. Your conditioning wasn’t where you expected it to be. You struggled to focus or found yourself running out of energy halfway through class.
Sometimes there are obvious reasons. Maybe you didn’t sleep well the night before, you’ve been carrying extra stress, or you’re fighting off the start of a cold.
But there’s another factor that’s often overlooked.
Did you give your body the fuel it needed before you asked it to perform?
At The Factory, we spend a lot of time talking about training, recovery, and consistency. Nutrition is an important part of that conversation, not because we believe everyone needs a perfect diet, but because your body needs fuel to get the most out of the work you’re already putting in.
The reality is this: your workout doesn’t begin when the warm-up starts. It begins with how you prepare your body beforehand.
Think of Your Body Like a Vehicle
Imagine leaving for a long road trip with your gas light already on.
Could you still make it down the road? Probably.
Would it be the smoothest or most reliable trip? Probably not.
Your body works much the same way.
Every workout requires energy. Whether you’re lifting weights, running intervals, playing soccer, preparing for volleyball season, or taking a group fitness class after work, your body needs fuel to meet the demands you’re placing on it.
That doesn’t mean you need to overcomplicate nutrition or obsess over every meal. It simply means recognizing that what you eat before training has a direct impact on how you’re able to perform during training.
The Four Players on Your Performance Team
Performance nutrition doesn’t have to be confusing. Think of it as four teammates, each with a different role.
Carbohydrates provide your body’s primary source of energy for moderate- and high-intensity exercise. During strength training, sprinting, interval workouts, and most sports, your muscles rely heavily on stored carbohydrates—called glycogen—to produce energy quickly.
Protein helps repair and rebuild muscle tissue after training. Every workout creates an opportunity for your body to adapt, and protein provides the building blocks that support that process.
Healthy fats contribute to hormone production, overall health, and provide energy during lower-intensity activity and throughout the day.
Fluids and electrolytes help regulate body temperature, maintain performance, and replace what is lost through sweat.
None of these nutrients work in isolation. Together, they help your body perform, recover, and adapt to training over time.
Not Every Tough Workout Is About Motivation
It’s easy to assume a difficult workout means you’ve lost motivation or aren’t making progress.
Sometimes that’s true.
More often, though, your body is simply responding to everything you’ve asked of it before you walked through the gym doors.
How did you sleep?
Have you been stressed?
Are you hydrated?
Did you eat enough today?
The workout itself is only one piece of the performance equation. Every decision you make leading up to training influences how your body responds once the workout begins.
That’s why two workouts that look identical on paper can feel completely different.
What Does the Research Say About Training Fasted?
Social media has made fasted workouts a popular topic. You’ve probably heard claims that exercising on an empty stomach burns more fat or leads to better results.
Like many topics in nutrition, the answer is more nuanced than a simple yes or no.
Research does show that training without eating beforehand increases the percentage of fat your body uses for fuel during that workout. However, current evidence has not consistently shown that fasted training leads to greater long-term fat loss when overall calorie intake is the same.
More importantly, moderate- and high-intensity exercise relies heavily on carbohydrates for energy.
For most individuals performing activities like strength training, CrossFit®, HYROX, interval training, recreational sports, or competitive athletics, consuming carbohydrates before exercise supports higher-quality performance and helps maintain training intensity throughout the session.
That doesn’t mean every workout requires a full meal beforehand. It simply means your body generally performs better when it has access to the fuel it needs.
There are exceptions. Some experienced endurance athletes intentionally complete certain lower-intensity sessions with reduced carbohydrate availability as part of a carefully structured training plan. These strategies are designed for very specific adaptations and are not intended to be everyday recommendations for the average athlete or fitness enthusiast.
For most people, showing up fueled allows them to train with greater quality—and higher-quality training is what drives long-term progress.
Timing Matters More Than Perfection
One of the most common questions we hear is:
“What should I eat before I work out?”
The better question is:
“How much time do I have before I work out?”
If you have two to three hours, a balanced meal containing carbohydrates, lean protein, and healthy fats is a great option.
If you have about an hour, choose a lighter meal or snack that emphasizes carbohydrates with a moderate amount of protein.
If you’re heading straight from work or school and only have 30 minutes or less, keep it simple. A banana, applesauce, toast with honey, pretzels, or a few dates can provide easily digested carbohydrates without sitting heavily in your stomach.
If you’re training in hot conditions, exercising for an extended period, or know you’re someone who sweats heavily, pair your pre-workout snack with water and an electrolyte beverage to help replace fluids and sodium lost through sweat. Coconut water can also be a refreshing option for lighter training sessions, though it naturally contains less sodium than most electrolyte beverages.
There isn’t one perfect pre-workout meal.
The best option is one that provides energy, agrees with your stomach, and fits consistently into your schedule.
(We’ll also be sharing a quick-reference guide on our social media with pre-workout snack ideas based on how much time you have before training.)
Coach’s Corner
One of the biggest misconceptions we see is people assuming they had a “bad workout” because they suddenly lost motivation or got weaker overnight.
Before jumping to that conclusion, ask yourself a few simple questions:
- Did I eat enough today?
- Am I hydrated?
- How did I sleep last night?
- Am I carrying more stress than usual?
Sometimes your body isn’t telling you to work harder.
It’s telling you it needs more support.
Consistency Wins
Performance nutrition isn’t about eating perfectly.
It’s about consistently giving your body the resources it needs to perform, recover, and improve.
Some days you’ll have time to prepare a balanced meal before training. Other days you’ll be grabbing a quick snack on your way to the gym. Both can fit within a healthy approach to fueling your body.
The goal isn’t perfection.
The goal is preparing your body well enough that each workout has the opportunity to produce the results you’re working so hard to achieve.
The Bottom Line
At The Factory, we believe every workout has a purpose.
Whether your goal is making the varsity team, preparing for your next HYROX race, building strength, improving your health, or simply having enough energy to keep up with your kids, your nutrition should support that goal.
You don’t need expensive supplements, a complicated meal plan, or to eat perfectly. You simply need to remember that your body performs best when it’s adequately fueled.
Your workout doesn’t start when class begins. It starts with how you prepare for it.
