Most people avoid starting CrossFit because they don’t know what’s going to happen, and walking into a room where everyone else knows the routine is its own kind of hard.
So here’s the whole thing, start to finish.
Before you get there
What to wear. Athletic clothes you can move in. Shorts or leggings, a t-shirt, regular athletic shoes. You don’t need lifting shoes, a weight belt, gymnastics grips, or anything with a brand on it. Nobody is looking at your shoes.
What to bring. A water bottle. That’s it. If you have a towel, bring it. Most gyms have chalk, and you won’t need it on day one.
When to arrive. Ten to fifteen minutes early. This isn’t about being polite — it’s because that’s when the coach can actually talk to you before the room gets busy. At our gym, coaches are on the floor at least ten minutes before every class specifically for this. Use it.
Eating beforehand. Something light, an hour or two out. Don’t show up having eaten nothing since breakfast, and don’t show up full.
Before the clock starts: paperwork and a conversation
You’ll fill out a waiver. Then, in those minutes before class officially begins, the coach will pull you aside and ask you some version of: what’s your background, what hurts, what are you nervous about?
Answer honestly. This is the single most useful two minutes of the hour. If you had a shoulder surgery in 2019, say so. If you haven’t exercised since college, say so. If your knees complain going downstairs, say so.
Coaches aren’t judging your starting point. They’re gathering the information they need to make the next hour work for you specifically. A coach who doesn’t know about your back is a coach who can’t protect it.
This is exactly why we ask coaches to be on the floor ten minutes early. That window isn’t padding. It’s when the coaching that matters most for a new person actually happens.
The hour, minute by minute Minutes What’s happening 0–10 General warmup 10–15 Workout brief 15–30 Strength work 30–40 Specific warmup 40–55 The workout 55–60 Cooldown and cleanup
Minutes 0–10: general warmup
Class starts with everyone doing the same thing. Light cardio — rowing, biking, a short jog — plus mobility and basic movement prep. Air squats, arm circles, lunges. Nothing heavy, nothing complicated.
The point is to raise your body temperature and get your joints moving. It’s also the coach’s first look at how you move before there’s any weight involved, which is why they’re walking the floor rather than standing at the front.
You may be a little winded by the end. That’s normal and it says nothing about how the rest of the hour will go.
Minutes 10–15: the workout brief
This is the part most people don’t expect, and it’s the part that makes the whole class less intimidating.
Before you touch a barbell, the coach walks the whole room through the entire day: what the strength work is, what the workout is, what the movement standards are, what the time domain looks like, and what the scaling options are.
You’ll know the plan for the next forty-five minutes before any of it starts. Nothing gets sprung on you. If you’re new, this is when the coach tells you specifically what your version of the day looks like — and if they haven’t, this is exactly the moment to ask.
Walk out of the brief knowing what you’re doing and you’ve removed most of the anxiety about a first class.
Minutes 15–30: strength work
The social part of the hour. Usually a strength lift — back squat, deadlift, press, that category — or a skill being built.
It’s slower and more deliberate than people expect. Rest between sets. A coach walking the floor correcting positions. It looks nothing like the CrossFit clips on Instagram.
If you’re new, you’ll likely be working with an empty barbell or a PVC pipe while the person next to you loads plates. This is not a demotion. Learning the pattern before adding load is the entire point, and every strong person in that room started exactly there.
Minutes 30–40: specific warmup
A second warmup, and one a lot of gyms skip.
The general warmup got your body ready to train. This one gets you ready for today’s workout specifically. You’ll rehearse the exact movements in the workout, at lighter loads, at the pace you’re about to do them. If the workout has dumbbell snatches and box jumps, you practice dumbbell snatches and box jumps.
Two things come out of this. Your body is primed for the specific demand instead of a general one — which is where a lot of injury risk lives. And you get to try every movement, with a coach watching, before it counts. If something feels wrong, you find out here, not four rounds into a workout.
For a first-timer this is the most valuable ten minutes of the class.
Minutes 40–55: the workout
This is the part everyone pictures when they hear “CrossFit.” Usually ten to twenty minutes, and designed to be hard.
Here’s what matters: hard is relative to you. Scaling options were on the whiteboard and covered in the brief. You already know which version you’re doing, because that got sorted twenty-five minutes ago.
The specifics vary daily — five rounds of rowing and dumbbell presses, or a running clock with a few movements you cycle through. What doesn’t vary is that a coach adjusts it to your capacity, not the other way around.
You’re going to breathe hard. You may need to stop and rest mid-workout. Both of those things happen to people who’ve been doing this for a decade.
One thing that surprises almost everyone: when you’re the last one finishing, the room doesn’t empty out. People stay and cheer. It feels strange the first time. It stops feeling strange fast.
Minutes 55–60: cooldown and cleanup
Some stretching, some conversation. The competitive energy drops off almost immediately and people just talk.
You’ll put your equipment away. Everyone does — there’s no staff cleaning up behind you. Then you go home.
What you’ll feel the next day
Sore. Probably more than you expect, and probably in places you didn’t know were involved.
This is called delayed onset muscle soreness, it peaks around 24 to 48 hours, and it’s a normal response to new movement patterns rather than a sign you did something wrong. It gets dramatically better after the first two or three weeks as your body adapts.
The best thing you can do about it is come back and move again. The worst thing you can do is wait until it’s completely gone, because by then you’ve lost the week.
The five things people worry about that don’t happen
Nothing gets sprung on you. Between the workout brief and the specific warmup, you’ll have heard the plan explained and physically rehearsed every movement before the workout starts. There is no moment where you’re standing there wondering what’s about to happen.
Nobody makes you do anything. If a movement doesn’t feel right, you say so and the coach gives you something else. That’s a normal exchange, not a confrontation.
Nobody is watching you. Everyone in that room is fully occupied with their own breathing. The self-consciousness is real and it is also entirely internal.
You won’t be the worst one there. And if you are, that’s a one-day condition. Someone newer walks in next week.
You don’t have to be fit first. This one comes up so often we wrote a whole post about it. You don’t get in shape and then start. Starting is how you get in shape.
You’re not going to get hurt because it’s CrossFit. Injury risk in coached CrossFit is comparable to running and lower than several sports nobody worries about. We covered the research in Is CrossFit Safe? The variable that matters is coaching quality, not the sport.
When a first class isn’t the right first step
Honest answer: for some people, dropping into a regular class on day one is the wrong move.
If you’re coming back from a significant injury or surgery, if you haven’t done any structured exercise in several years, or if the idea of a group class is a genuine barrier rather than mild nerves, you’re better served starting one-on-one and joining classes once the basics are in place.
That’s why our primary entry point isn’t a class at all — it’s the 90 Day Transformation, which starts with four personal training sessions before you’re ever in a group setting. You learn the movements with a coach’s full attention, then walk into your first class already knowing what a good squat feels like.
Some gyms will put you straight into class on day one. Some people do fine that way. But if you’ve been putting this off for two years because you don’t want to be the person who doesn’t know what’s going on — start where you’ll be set up to succeed.
Frequently asked questions
How long is a CrossFit class? One hour. At our gym that breaks down as a ten-minute general warmup, a five-minute workout brief, fifteen minutes of strength work, a ten-minute specific warmup, fifteen minutes for the workout itself, and five minutes of cooldown. The high-intensity portion is only about fifteen minutes of the hour.
Will I know what the workout is before it starts? Yes. There’s a dedicated workout brief about ten minutes into class where the coach walks the whole room through the day’s strength work, the workout, the movement standards, and the scaling options — before anyone touches equipment. Then there’s a second, workout-specific warmup where you rehearse the exact movements at light load before it counts.
Do I need to be in shape before my first CrossFit class? No. Every workout is scaled to the person doing it. The starting point is wherever you currently are.
What should I wear to my first CrossFit class? Athletic clothes you can move freely in and regular athletic shoes. No specialty gear is needed.
Will I be able to walk the next day? Yes, though you’ll be sore. Soreness peaks 24 to 48 hours after and improves substantially within the first few weeks of consistent training.
How much does a CrossFit membership cost? Coached group training in the metro Atlanta area generally runs in the $175 to $250 per month range, depending on the gym and the membership. We broke down the full local market in What Does a Gym Membership Actually Cost Around Decatur, Clarkston, Avondale Estates, and Tucker?
Can I try a class before I sign up? At most gyms, yes. Ours starts with a free intro conversation — about thirty minutes, no pressure — so we can figure out the right starting point for you.
How soon will I see results? Energy and sleep improve within two to four weeks for most people. Visible body composition changes take closer to three months. We laid out the full timeline in How Long Before I See Results from CrossFit?
If you’re still on the fence
The uncertainty you’re feeling is the whole reason this post exists. Almost nobody’s first class is as bad as the version they imagined for six months beforehand.
CrossFit Liminal is in Clarkston, about ten minutes from downtown Decatur and five from Avondale Estates. You can see our clas schedule here.
