From diaper rash cream to panic on the rower; the battles nobody talks about.

I want to talk about the real first week of CrossFit because I want you to know that you’re not out of your mind and you’re not the only one. If you’re living in a larger body and you just started this journey, you might be feeling things right now that you’re too embarrassed to talk about.

You hear the smaller people in the 5am class complaining about soreness. They laugh about their quads hurting or how hard it is to wash their hair. But you? You’re dealing with things they don’t even know exist. You’re battling physics on a whole different level.

panic on the machines

Nobody warns you about the machines. You sit down on the rower and it pins you in place. It’s not just that your stomach presses against your thighs and cuts off your air; it’s that the foot pedals are so narrow that your legs are forced together in a way that is physically painful.

You don’t have to strap in. The foot pedals are extremely narrow and they were designed around a smaller skeleton. When you have larger thighs and you force your feet that close together, your legs rotate inward, your ankles collapse toward each other, and your knees get pushed out of their natural tracking. That chain reaction creates friction in the thighs, torque in the knees, and strain through the ankles and hips, which is why the pain shows up fast and feels sharp. Put your feet on the floor. Or drop one foot down and just row with the other. Make the machine work for you, don’t keep yourself in pain trying to fit the machine.

And then there is the bike. That tiny seat wasn’t made for you. In that first week of CrossFit, it feels less like a seat and more like a thong that’s trying to slice you in half. It hurts in a way that makes you not want to get on it ever again. It’s going to take time to get used to it, but just know that the discomfort you feel there is normal. You’ll get used to it. 

the “kids’ table” syndrome

Then comes the moment the class starts lifting. Everyone else grabs a barbell and starts loading weights and making noise. But the coach hands you a PVC pipe or a light dumbbell.

Logistically, you know they’re keeping you safe. But emotionally? It feels like being sent to the kids’ table at Thanksgiving. You feel infantilized and feeling sorry for yourself starts to creep in.

You’ve got to reframe this immediately. You’re learning positions, patterns, and control that your body needs before load gets added. Strength comes from patience and from earning the next step.

the strategic “hiding” spot

You might find yourself gravitating toward the corner of the gym, right next to the weight rack. A coach might try to encourage you to move into the center, thinking you’re “hiding” or being shy.

Many of them don’t understand that when you’re carrying hundreds of pounds of body weight, walking across the gym to get a dumbbell or a plate is a workout all by itself. I get it; you’re conserving energy. 

Stay in your spot. If being near the rig makes the logistics easier, or simply makes you feel more comfortable, plant your damn flag there. If someone tries to pull you into the middle of the room, a simple wave and “I’m good right here” is enough. You don’t owe an explanation.

the friction and the flu

By day three or four, the “chub rub” hits, and it’s agony. It’s not just discomfort; it’s raw, stinging skin between your legs or under your arms that burns every time you move. I’m going to be honest, this takes out more people in the first week of CrossFit than burpees. Unfortunately your coach might not even know the gravity of this. It’s not just rubbing, the skin can open, crack, and bleed.  

Don’t suffer through this. Go to the store and get barrier cream to keep this at bay. If it’s already cracking and bleeding, get the the good old-fashioned diaper rash cream. It’s the only thing that’s going to soothe the fire. It’s not glamorous, but it will keep you going.

You might also feel sick. You might get home and feel shivery, exhausted, and foggy and you think the workouts are making you sick, but they’re not. This is metabolic shock. Your body is releasing myokines and inflammatory markers because it’s confused by the new stimulus. Drink water, sleep, and ride it out. This part is temporary. Your body adapts fast, and this will go away. It means the work is happening.

the scale lies

This is the most dangerous trap of Week One. You’ve worked harder than you ever have in your life. You’re sore, you’re tired, and you’ve been eating well. So you step on the scale on Friday morning expecting a reward… and the number has gone up.

If you don’t know the science, this might push you over the edge. You’ll think, “I’m working this hard and getting fatter?” No. You’re inflamed. When you damage muscle tissue (which is what exercise does), your body floods the area with fluid to repair it. You’re retaining water like a sponge. That three-pound gain isn’t fat; it’s inflammation. Don’t touch the scale this week and if I were you, I wouldn’t touch it next week either.

the hunger panic

Around Thursday, your brain might go into panic mode. It senses a massive energy deficit and it’s going to scream for sugar. You might find yourself staring at an empty pizza box, wondering how you let this happen.

The shame spiral hits hard. “I ruined it.” You didn’t ruin it.  Your body is trying to save you from what it thinks is starvation. Acknowledge it, forgive yourself, and get back to the gym tomorrow. One meal does not undo a week of work.

the sabotage

Finally, you’ve got to be ready for the comments. It might happen in your kitchen or at work. Someone in your inner circle might roll their eyes and say, “Oh, you’re doing the New Year thing again?” or “Good for you,” with that tone that implies they think you’re going to quit.

It’s going to sting. You’re going to want to snap back at them. Don’t. Save that energy for the workout. You don’t need to convince them or defend yourself. Let your consistency do the talking while you keep your energy focused on getting through the week.

you can make it

Your first week in CrossFit is going to be messy. It’s going to hurt in places you didn’t expect, and it’s going to test your resolve in ways nobody warned you about. But if you can navigate the equipment, leave the scale alone, and take care of your body, you will make it to Week Two.

You’re not going to see progress if you leave. You got this.
