The Fitness Fix You’re Ignoring: Why Sleep Deserves a Spot in Your Training Plan
Lynne Steiner • July 7, 2025
Picture this.
You hit your WOD with the force of a caffeinated freight train. You meal-prepped like a macro-tracking wizard. You even foam rolled (without whining, mostly). But you’re still stuck. The scale won’t budge, the barbell won’t move, and your motivation is flatter than a protein pancake.
Here’s a wild idea: What if the secret sauce isn’t another supplement or sweat session—what if it’s...sleep?
Yep. The free, wildly underrated, unsexy performance enhancer that you’re probably ignoring while doomscrolling at midnight.
Let’s break it down.
🧠 Sleep Is Not a Luxury—It’s the Foundation
Think of your training as a high-performance machine. Lifting, sprinting, and squatting are the gas pedal. Sleep? That’s the oil that keeps the whole engine from exploding.
Without it, even the best athletes fall apart like IKEA furniture without the manual.
- Your muscles repair while you sleep.
- Your hormones regulate during sleep.
- Your brain consolidates movement patterns and skills through sleep.
In other words—no sleep = no progress. You’re trying to build a castle on a swamp.
🔥 Pain Point 1: No Sleep = No Fire in the Tank
You know that groggy, slow-motion-wading-through-molasses feeling?
That’s your body crying out for sleep, not another cup of cold brew.
- When you sleep less than 6 hours, your endurance drops.
- Your rate of perceived exertion (a fancy way of saying “this feels like death”) goes up.
- Even your strength output suffers—studies show one bad night can slash performance by 10-20%.
So, if you’re dragging your feet through a warm-up, don’t blame your programming—blame Netflix.
Lack of sleep also sucks the joy out of training. Your motivation plummets, your mental grit erodes, and soon you're ghosting workouts like an ex with no closure.
🍟 Pain Point 2: Sleep Deprivation Turns You Into a Gremlin
And not the cute kind.
When you sleep like garbage, your body’s hunger hormones—ghrelin and leptin—go completely off the rails.
- Ghrelin (the “feed me now” hormone) skyrockets.
- Leptin (the “I’m full” hormone) gets ghosted.
The result?
- You're ravenous all day.
- You crave sugar like it’s oxygen.
- And you make decisions like a raccoon at a 2 a.m. dumpster buffet.
Combine this with low energy and poor willpower, and your clean eating plans crash harder than your 3 p.m. caffeine high.
Worse still: sleep also affects muscle-building hormones, like testosterone and growth hormone. Skimp on shuteye, and your body stops building muscle and starts hoarding fat like it’s prepping for hibernation.
🛠️ Want Better Workouts? Start With Better Sleep.
This isn’t about becoming a monk who drinks chamomile tea in candlelight every night. You don’t need a 12-step ritual or a $600 mattress.
Start small. Aim for consistency. Treat sleep like part of your training plan.
Here’s how:
- Go to bed and wake up at the same time—even on weekends. (Sorry, Sunday sleep-ins.)
- Avoid screens 30-60 minutes before bed. Blue light = brain party = no sleep.
- Cool, dark, quiet room = sleep sanctuary. Make it a cave, not a concert.
- Cut caffeine after 2 p.m. Yes, even your iced Americano. I’m sorry.
- Add just 30 more minutes of sleep per night this week. That alone can change the game.
🏁 Final Thoughts: Sleep Is a Performance Multiplier
You don’t need more hustle.
You need more recovery.
Because when you sleep well, your body does everything better:
- You lift heavier.
- You recover faster.
- You eat smarter.
- You feel like showing up.
So if you’re grinding through workouts but spinning your wheels, maybe it’s time to stop grinding and start snoozing.
Sleep is not a weakness. It's a weapon.
Now go sharpen it.

Gym Etiquette 101: How to Be a Great Member Walk into any gym and you’ll see two types of people. The first? The silent hero. They finish a set, wipe down the bench, re-rack the dumbbells, and glide away like a ninja of courtesy. You barely notice them, because everything just flows. The second? The gear hoarder. They’re building a fortress with kettlebells, chalking the air like LeBron before every set, and—oh look—there’s their sweat angel plastered across the bench you were about to use. Which one would you rather train with? Being a great gym member isn’t about lifting the heaviest barbell or crushing the fastest metcon time. It’s about something simpler (and honestly, more impactful): respecting space and equipment so that everyone’s workout is smoother, safer, and more enjoyable. Let’s talk about two big etiquette mistakes—ones that make or break the training experience—and how to avoid them. Equipment Hoarding: The Fitness Equivalent of Cutting in Line Picture this: you’re at an all-you-can-eat buffet. But one guy grabs an entire tray of shrimp, guards it like treasure, and leaves everyone else staring at empty platters. That’s what equipment hoarding looks like in the gym. - Why it matters: In a CrossFit class, equipment is a shared resource. When you “claim” four different bars, two sets of dumbbells, and a rower for yourself, you’re essentially telling your classmates, “Sorry folks, the buffet’s closed. I’m the shrimp king now.” - How it affects the room: It slows everything down. Other people have to wait, ask awkwardly to “work in,” or skip a movement altogether. Not exactly the community vibe we’re going for. Quick fix: Only take what you need for that moment. If the workout calls for a barbell, grab a barbell—not a barbell plus three kettlebells “just in case.” You’ll always have access to what you need if everyone plays fair. And if you’re worried about losing your equipment mid-class? Relax. Nobody’s plotting a barbell heist while you tie your shoes. Clean Up: Your Sweat, Your Responsibility Here’s a truth bomb: nobody wants to accidentally sit in your sweat puddle. Leaving behind your DNA in chalk, sweat, or skin flakes (yep, it happens) is the fastest way to turn your gym into a biohazard site. It’s also, quite frankly, gross. - Why it matters: Hygiene is respect. Sweat and germs spread quickly, especially in group classes. By wiping down your gear, you’re saying, “I care about the next person who has to use this.” - The bigger impact: It keeps the gym safe and smooth-running. Nothing derails a class faster than someone slipping on a sweaty pull-up bar. Quick fix: Wipe down everything you touch—rower handles, barbells, benches, the works. Most gyms have spray bottles and towels everywhere for a reason. And let’s not forget re-racking weights. Leaving plates scattered on the floor is like leaving Legos in the hallway—it’s a guaranteed trip hazard and a guaranteed curse word waiting to happen. Why This All Matters: More Than Just “Rules” Some people roll their eyes at gym etiquette, like it’s a fussy set of rules written by the “Fun Police.” But etiquette is actually about energy. When everyone shares equipment fairly and cleans up after themselves, the room feels lighter. Workouts move faster. People smile more. Coaches can coach instead of playing janitor. It’s not about rules—it’s about respect. And respect is the glue that holds a strong community together. The Takeaway (and a Simple Tip to Try Today) Being a great member doesn’t require you to be the fittest, the fastest, or the strongest. It requires something far simpler: thoughtfulness. Here’s the cheat code: - Use only what you need. - Clean up when you’re done. - Re-rack like a legend. Do those three things and you’re not just a member—you’re the kind of person others want to train with. So the next time you finish a set, think about the person waiting behind you. Wipe it down. Re-rack it. And in that small, ninja-like act of courtesy, you’ll pass on the positive vibe that makes your gym one of the best places to be.

Picture this: your alarm blares at 5:30 a.m. and suddenly you’re negotiating with yourself like a lawyer in a courtroom drama. “If I skip today, I’ll go tomorrow.”“ If I just get more sleep, I’ll perform better next time.” Sound familiar? Here’s the hard truth: the universe is not going to clear your schedule, tuck your kids into bed early, or refill your coffee pot so you can have the “perfect” conditions to work out. Life is messy, chaotic, and sometimes downright rude. And yet, the secret to fitness success isn’t buried in some obscure training manual or locked inside a macro-tracking app. It’s simpler—and harder—than that. The real secret is showing up. Especially when you don’t feel like it. Why Obstacles Aren’t a Sign to Stop Life throws haymakers daily: - Your boss schedules a late Zoom meeting. - Your kid has soccer practice that somehow requires three hours of driving for a one-hour game. - Dinner burns because you answered a work email and forgot the chicken in the oven. At the end of the day, your workout starts to look like a luxury cruise: nice in theory, impossible to board. But here’s the twist: those obstacles aren’t signals to quit—they’re signals that this is the exact moment you need movement most. - Busy schedules convince us there’s no time. But what if fitness isn’t competing with your schedule—what if it’s fueling it? A 30-minute class can give you more focus for the next eight hours. That’s a return on investment Warren Buffett would be proud of. - Stress and fatigue whisper that skipping a workout is the “safe” choice. But skipping doesn’t recharge your batteries—it drains them further. Exercise is the world’s most underrated stress relief valve. Miss it, and you’re building pressure until the lid blows off. The Psychology of Just Showing Up Here’s a fun fact: your brain is terrible at measuring effort. It screams, “This will be awful!” before you even touch a barbell. But once you walk through the door, say hi to your coach, and start the warm-up, the story changes. Suddenly, what felt impossible feels… doable. Think of it like dragging your feet to a party you didn’t want to attend. You almost bailed three times. Then you show up and—what do you know—you’re laughing, eating chips, and wondering why you resisted in the first place. Fitness works the same way. The hardest lift is the front door. Flip the Script: How to Show Up When You Don’t Feel Like It Instead of chasing “perfect conditions,” practice this mindset: - Shrink the workout. Don’t have an hour? Do 20 minutes. No gym? Knock out squats and push-ups in the living room. Something is always better than nothing. - Anchor to identity. Stop saying, “I have to work out.” Start saying, “I’m the kind of person who trains, even when it’s hard.” That tiny linguistic tweak shifts your brain from obligation to ownership. - Stack the deck. Lay out your workout clothes the night before. Book your class in Wodify. Tell a friend you’ll meet them there. Future-You will be grateful when Current-You tries to chicken out. The Conclusion (And a Pep Talk) Here’s the takeaway: the secret sauce isn’t motivation, luck, or perfect conditions. It’s the gritty, stubborn decision to show up anyway. - Your schedule will always be busy. - Your energy will sometimes be low. - The stars will never align just right. But when you show up through the chaos, you win. Every. Single. Time. Pro Tip: Next time you’re tempted to skip, try this: tell yourself, “I’ll just go for the warm-up.” If after 10 minutes you still want to leave, you have permission. (Spoiler: you won’t.) So lace up your shoes, roll your eyes at your inner excuses, and step into the arena. Because the only true failure in fitness isn’t a missed lift or a slower run—it’s not showing up at all.
