Ask ten coaches how they warm their clients up and you’ll get ten different answers. Some send people to the treadmill for five minutes. Some hand them a foam roller and point at whatever’s tight. Some run through the same six dynamic stretches before every single session, regardless of what that session is. None of these approaches are wrong, exactly. They all raise body temperature, get some blood moving, and make the first working set feel less like waking up a dead limb. But raising your temperature was never the hard part of warming up. The hard part is figuring out if the joint you’re about to load can actually get to the position you’re about to ask it for.
Doing something beats doing nothing
Walking, biking, light circles through the joints, a few minutes on the roller. All of it works, in the narrow sense that it works. Movement increases blood flow to the tissue you’re about to train. Warmer muscle and connective tissue conducts force more efficiently and tolerates a bigger range before something feels tight or restricted. Foam rolling adds something on top of that: a real, if temporary, drop in stiffness and a modest bump in range of motion, without the strength and power costs you’d get from holding a static stretch cold (1). If your only goal is to feel ready, any of this gets you there, and I’m not going to pretend otherwise. We’ve made the longer case for what foam rolling actually changes and what it doesn’t over in FRC vs foam rolling; the short version is that it’s a legitimate way to feel looser before you train, and a poor way to build the range you’re trying to feel looser in.
Feeling ready and being ready aren’t the same thing, though. A joint can feel loose because you spent two minutes rolling over the muscle around it and still have no active control anywhere near its actual end range. That gap doesn’t show up on the roller. It shows up mid-set, when you ask a hip to get somewhere it’s never had to go under load, and something else compensates to get you there anyway.
The problem most warm-ups never solve
Most programming warms up patterns. Push, pull, squat, hinge, carry, done. What it rarely asks is if the joints underneath those patterns can actually get where the pattern needs them to go. Can your shoulder reach full flexion without your low back arching to finish the job? Does your hip rotate enough to let you sit into a deep squat without your knees caving in to find the range your hip won’t give you? A generic warm-up assumes the answer is yes for everybody in the room. A useful one checks first, and it checks the joint, not the pattern, because the pattern is only ever as good as the joints doing the work underneath it.
This is also the point where I’ll push back a little on my own field. A lot of mobility coaching talks about warm-ups like the answer is just adding more drills. More bands, more circles, more corrective exercises stacked in front of the actual training. That’s not the fix. The fix is asking a better question before you add anything at all.
What CARs actually check before you load anything
This is where CARs, controlled articular rotations, earn their place. They’re not another warm-up drill stacked on top of the others. They’re a way of asking each joint what it’s got today, in the same motion that also happens to raise tissue temperature and prime the joint for work. Done well, a CAR is neurologically demanding in a way a joint circle from gym class never was: full-body tension held everywhere except the joint doing the work, which rotates through its complete available arc under muscular control rather than momentum.
We’ve written the deeper explanation of why that distinction matters, and how to build a full CARs sequence joint by joint, in the complete CARs guide. Worth flagging here since it comes up constantly: a CAR that clicks, catches, or pinches at a specific point isn’t automatically a red flag. Painless, consistent clicking is usually just how that joint sounds and always has been. What’s worth paying attention to is a new catch, a pinch that shows up at the same spot every time, or a spot that’s gotten worse over a few weeks. That’s information your warm-up just handed you for free, before you loaded anything.
The point for this article is narrower than the full CARs explanation, though. CARs double as your assessment and your warm-up in the same ten minutes, which is more than you can say for a treadmill or a roller. That’s the whole case for building your warm-up around them instead of around whatever felt tight yesterday.
Broad, then specific, then broad again
Once you’ve run CARs through the joints you’re about to train, upper body day means shoulders, elbows, and spine, lower body day means hips, knees, ankles, you’ve got real information. Something felt restricted. Something clicked or caught in a spot it shouldn’t. That’s your cue to go specific for a minute or two before you load anything. A shoulder that struggled with external rotation gets a set of banded external rotations or a scarecrow before you press overhead. A hip that felt locked in internal rotation gets a 90/90 transition before you squat. This isn’t a menu of corrective drills you run through regardless of what CARs told you. It’s the opposite. CARs tell you where to spend the extra ninety seconds, and everywhere else, you skip straight to training.
From there you go broad again: a few reps of the actual pattern you came in to train, light and unloaded, so the nervous system gets one more rehearsal of the whole movement before the working weight goes on. That’s the full arc. Broad to check general readiness and raise temperature, specific to address what the check turned up, broad again to rehearse the pattern you’re about to load. Ten to fifteen minutes, most days, and it’s doing three jobs instead of one.
Warming up for Austin’s version of stiff
Context changes what stiff actually means without changing the framework underneath it. In August, when it’s a hundred degrees before nine in the morning, people show up already sweating and assume that means they’re warm. Sweating isn’t the same as your hip having active control at end range. A joint that’s been locked into the same forty-five degrees of flexion at a desk chair all day doesn’t loosen up just because the parking lot was hot. In January, when mornings are actually cold for once, the same joints show up genuinely stiff on top of whatever the desk did to them, and the broad pass at the start needs a little more time before you go specific.
Desk-heavy clients, and this is most of the tech workforce we train out of St. Elmo, show up with a fairly predictable pattern: hips that don’t want to extend, thoracic spines that don’t want to rotate, shoulders that have forgotten what full flexion feels like. For those people, the CARs portion of the warm-up isn’t optional or a nice-to-have. It’s the only part of the hour where those joints get asked to do something other than what eight hours in a chair just did to them. Anyone training outside on the Greenbelt or Lady Bird Lake has a second layer on top of that: uneven ground asks the ankles and hips for stability the gym floor never demands, and a few minutes of ankle and hip CARs before a trail run is cheaper than finding out mid-trail that your ankle doesn’t have the range it needs. Same logic applies if pickleball is your outdoor activity of choice instead of a trail; the lateral shuffle and the sudden stop-start demand hip rotation most people never check until a game asks for it under speed.
This isn’t the same as your daily CARs practice
Worth separating two things that sound identical but aren’t. What this article is describing is CARs used as a pre-training warm-up: ten minutes before you lift, run, or play, aimed at the joints that session is about to load. That’s different from running CARs as a standalone daily practice, first thing in the morning, on days you’re not training at all. Both are legitimate uses of the same tool, and honestly the daily version is the one that does more for long-term joint health, since it’s not competing for time with everything else in a training session. If that’s the piece you’re actually after, why your morning routine should start with CARs covers that case specifically. This article is about the ten minutes before you train. That one is about the other twenty-three hours and fifty minutes.
Why I won’t hand you a universal drill list
I’m not going to give you five corrective exercises to bolt onto every warm-up, because I don’t know what your joints are doing today, and neither does anyone reading a blog post about warm-ups. That’s the actual argument for assessment. We use the Functional Range Assessment with new clients for the same reason CARs matter inside a single warm-up: you can’t train what you haven’t checked. If you’re training with us in Austin, that assessment plus personal training built around it removes the guesswork entirely. If you’re training on your own, KINSTRETCH Online will teach you to run CARs correctly and read what they’re telling you, which is most of what a coach is doing for you in the first five minutes of a session anyway.
A warm-up that only raises your temperature is doing a third of the job. Check the joint, address what the check found, then go train. That’s the whole framework, and it works with fifteen minutes before a squat session or five minutes before you walk out the door to the Greenbelt.
A few questions that come up
Is foam rolling before training a waste of time
No. It’s a reasonable way to feel looser before you start, and the evidence doesn’t suggest it costs you strength or power the way holding a cold static stretch can. It just isn’t checking anything or building anything. Use it if it helps you feel ready, and don’t mistake that feeling for the joint having gained control it didn’t have an hour earlier.
How long should a warm-up actually take
Five to fifteen minutes covers most sessions. The time isn’t the variable that matters most. What that time actually went toward, checking your joints or just raising your temperature, is the variable that matters.
Is this the same thing as stretching before I train
No. Stretching, especially held cold before a session, mostly changes how much sensation you’re willing to tolerate at a given range, not how much active control you have there. CARs are asking a different question: can you get to that range and hold it under your own tension, not can you get pushed into it.
Can a good warm-up actually prevent injury
It reduces risk more than it eliminates it, and it does that by catching a restriction before it becomes the compensation that gets you hurt. A joint that shows you a clean, controlled range during CARs is a joint you can load with more confidence. A joint that catches or restricts somewhere is telling you exactly where to be more careful that day.
Should I be doing CARs every single day, not just before training
If your goal is long-term joint health rather than just a better warm-up, yes, and that’s a different conversation from this one. Daily CARs practiced independent of training is where most of the durability gains come from. What’s in this article is the pre-training version aimed at whatever you’re about to load.
