Having a good warm-up can be the difference between hitting a PR and missing it again. Yet a lot of CrossFitters either make it way too complicated or skip it entirely.
The best warm-up is one that preps you for the work you're going to do, and nothing more. Here's the simple structure I use before most sessions. The final step changes slightly depending on whether you're doing regular working sets or going for a max (weight or reps).
Step 1: Get Warm
Start by actually getting warm. Pick a machine and spend 5 to 10 minutes gradually bringing your heart rate up. I usually start slow and work my way to a light sweat, around 75% of max heart rate. This gets blood flowing and preps your body to start working.
Step 2: Mobility and Activation
Next is mobility and activation work. This should target the joints and muscles you're going to use in the session. If you have mobility restrictions, attack those. If certain muscles always need activating, do that. Keep it focused and efficient. 5 to 8 minutes is plenty. Nothing more.
Step 3: Build Into the Movement
After mobility, start working directly on the exercise you're about to do.
Begin with an empty bar for 10 to 15 reps. Then move to roughly one third of your working weight for 5 to 10 reps. Next, go to two thirds for another 5 to 10 reps.
If you're doing regular training sets, jump straight up to your working weight and begin your sets.
If you're maxing out for weight or reps, work up in small steps from the two-thirds mark until you reach your target weight. Avoid doing too many reps between 90 and 100 percent. Those can take too much out of you before the actual working set.
Key Takeaways
Keep it purposeful. Warm up for the specific work ahead, not just to feel good.
General to specific. Start with cardio to raise temperature, move to targeted mobility, then progressive bar work.
Save energy for the main sets. Especially on max days, limit heavy reps during the ramp-up.
Consistency beats complexity. A repeatable three-step process works better than random long warm-ups.
Frequently Asked Questions
How long should my warm-up take?
Most sessions fit in 15 to 20 minutes total using this structure. Adjust the ramp-up based on how recovered you feel and the demands of the workout.
Does this work for every movement?
Yes. The three steps apply to almost any exercise. Change the activation drills and bar progression to match the movement pattern.
What if I feel ready after step one?
Still do the mobility and activation. Skipping them often leads to feeling off once the working weight hits the bar.
