If you’ve ever walked past a CrossFit box (yep, that’s what they call their gyms) and heard people grunting, barbells clanging, and a coach shouting encouragement, you’ve probably wondered… what’s going on in there? CrossFit isn’t your typical “hop on the treadmill and call it a day” kind of workout. 

It’s a mix of weightlifting, cardio, and bodyweight movements, all packed into high-intensity sessions designed to push you past your comfort zone and build serious strength and stamina.

What makes it so addictive for many people is the variety. One day you might be flipping heavy barbells with a clean & jerk, and the next you’re grinding through burpees, box jumps, or rowing sprints.

No two workouts are the same, which keeps things exciting and your body constantly adapting. And the best part? It’s scalable. Whether you’re a total beginner or an elite athlete, your coach can tweak the movements and weights so you can train safely while still getting results.

In this guide, we’re breaking down the top CrossFit exercises that can skyrocket your strength and endurance, based on movements ranked from the CrossFit Open (the sport’s global annual competition). 

You’ll also get tips on structuring your workouts for strength vs. conditioning days, plus how to keep your CrossFit classes packed using Rezerv’s scheduling and marketing tools. So, grab your chalk, lace up your shoes, and let’s dive in.

Overview: What is CrossFit & Class format

At its core, CrossFit is a high-intensity training program designed to make you ready for just about anything life (or sport) throws your way. Instead of specializing in one type of exercise, it blends elements from weightlifting, cardio, and gymnastics into constantly varied workouts.

This means you might be squatting heavy one day, swinging kettlebells the next, and sprinting or rowing the day after. The goal? Build a well-rounded mix of strength, stamina, agility, and speed.

Most CrossFit classes follow a similar structure, even though each “box” (CrossFit term for gym) operates independently. Sessions typically run about an hour and start with a workout brief, where the coach explains the “WOD” (Workout of the Day) and demonstrates the movements. After that, you’ll warm up with mobility drills or light cardio, then move into strength or skill work, think practicing Olympic lifts like the clean & jerk or refining your pull-up form.

The heart of the class is the conditioning workout, usually lasting 10–30 minutes. This is where the intensity ramps up. Depending on the WOD, you might do an AMRAP (as many rounds/reps as possible in a set time) or an EMOM (every minute on the minute). Finally, there’s a cool-down to help you recover and reduce soreness.

What’s great is that everything can be scaled. Newer athletes might use lighter weights, adjust movements, or work at a slower pace, while seasoned CrossFitters push heavier and faster. This makes it one of the few training styles where you can have total beginners and competitive athletes sweating side-by-side, and still get equally effective workouts.

Most common CrossFit movements ranked from open workouts

If you’ve ever watched or participated in the CrossFit Open, the annual worldwide competition that tests athletes across multiple workouts, you’ll notice certain movements show up year after year.

These aren’t just random picks; they’re the bread-and-butter of CrossFit training, chosen because they challenge multiple muscle groups, test endurance, and demand solid technique.

At the top of the list are thrusters (a front squat immediately followed by an overhead press). They’re brutal because they work your legs, core, and shoulders all in one go, while also spiking your heart rate. Close behind are burpees, the ultimate bodyweight punishment that builds explosive power and stamina without any equipment.

Wall balls, throwing a medicine ball to a target while squatting, are another Open favorite, combining lower-body strength with coordination and cardiovascular endurance.

You’ll also see heavy-hitters like deadlifts for raw pulling strength, and clean & jerks for explosive power and full-body coordination. Even gymnastics-style moves, such as toes-to-bar and pull-ups, often make the cut because they test both grip strength and midline stability.

By tracking which movements dominate the Open, you can prioritize training for the ones most likely to improve overall performance. These exercises aren’t just competition staples, they’re also fantastic for building functional fitness that translates directly into everyday strength and resilience.

Essential exercises: Burpees, Thrusters, Wall Balls, Deadlifts, Clean & Jerks

When it comes to building both strength and stamina in CrossFit, these five exercises are non-negotiable. They hit multiple muscle groups, challenge your cardiovascular system, and build the kind of functional strength you can use inside and outside the gym.

Burpees may be simple, but they’re a full-body test of grit. Dropping to the floor, pushing up, and jumping back to your feet over and over forces your heart rate up fast, making them perfect for conditioning and mental toughness.

Thrusters combine a front squat with an overhead press, meaning your legs, core, and shoulders work in one fluid movement. They’re especially taxing because they demand both power and endurance, you can’t slack on either.

Wall balls bring a unique twist by adding coordination to the mix. You’ll squat with a medicine ball, then launch it to a high target. Done in high reps, this move quickly teaches you how to manage fatigue while keeping form sharp.

Deadlifts are the ultimate raw strength builder. By lifting a loaded barbell from the ground to a standing position, you develop powerful hamstrings, glutes, and lower back muscles, critical for safe lifting and athletic performance.

Finally, clean & jerks are the Olympic lift that blends strength, speed, and precision. You’ll lift the bar from the ground to your shoulders (the clean), then drive it overhead (the jerk). It’s a full-body challenge that improves explosive power and coordination.

Mastering these five movements gives you a solid foundation for almost any CrossFit workout. They’re tough, but once you nail them, you’ll notice your overall performance skyrocket.

Structuring classes: Strength vs conditioning focus

A great CrossFit program isn’t just about doing random hard workouts, it’s about balancing strength training with conditioning so you can build power without sacrificing endurance. The two go hand-in-hand, but they serve different purposes.

Strength-focused sessions usually start with a primary lift, like deadlifts, squats, or clean & jerks. The goal here is to lift heavy with proper form, often in lower rep ranges (e.g., 3–5 reps per set) and with plenty of rest between sets. This builds raw power, reinforces technique, and helps prevent injury when you go heavier or move faster in other workouts.

Conditioning-focused sessions, often referred to as “metcons” (metabolic conditioning),are all about pushing your cardiovascular limits. These workouts are typically shorter but more intense, involving bodyweight movements, lighter weights, or mixed modalities like rowing, biking, and running. Formats like AMRAPs and EMOMs are common, keeping you moving under fatigue.

Many CrossFit boxes blend the two in a single class: you might spend the first half building strength with heavy lifts, then finish with a fast-paced conditioning circuit. Others dedicate entire days to one focus. The key is variety, enough heavy work to make you stronger, paired with enough conditioning to keep you quick, agile, and resilient.

When your training strikes that balance, you’ll see progress across the board: heavier lifts, faster workout times, and better stamina for everything from sports to daily life.
