You're Not Warming Up. You're Just Starting Early.
Most people confuse moving around with preparation. They're not the same thing.
I completed the Rogue Enduro Challenge this week. It was the first time I've entered an online fitness contest. The workout can be seen here: Rogue Enduro Challenge! I've always struggled with warming up for fitness activities. In the early days, I didn't need it much. Now, if I don't do it, I don't perform well. For this event, which you complete on your own time, I spent about 60 minutes warming up.
Sixty minutes. Not training. Preparing.
When I tell people that, the reaction is usually somewhere between surprise and skepticism. Sixty minutes seems like a lot when you've spent years walking in the door, hopping on a bike for five minutes, and calling that a warm-up. But what most people are doing before a session isn't preparation. It's just early movement. There's a difference, and it matters more than almost anything else you do in the gym.
What a Warm-Up Is Actually Supposed to Do
The common understanding of a warm-up is that you raise your heart rate a little, loosen up your joints, and get the blood flowing. That's not wrong, but it's incomplete to the point of being almost useless as a framework. A properly designed warm-up does something far more specific: it tells your nervous system it's time to work.
Your muscles don't just turn on. They fire in response to signals, and the quality of that signal determines how much force you can produce, how accurately you move, and how quickly you can access the muscle fibers you need. A cold, unprimed body produces a degraded signal. A properly prepared one does not. The difference shows up in your first rep, your peak output, and your injury risk across the session.
Most people get a fraction of the preparation they need and skip the rest.
The Part Nobody Talks About
There's a well-established principle in exercise science that a properly constructed warm-up doesn't just prepare you for the session. It temporarily elevates your performance capacity above your baseline. In practical terms, you can be more capable coming out of a good warm-up than you were when you walked in the door. More powerful, more coordinated, more able to access what you've built.
That window doesn't last long. But it's real, and it's one of the reasons elite athletes and serious competitors invest significant time in preparation before they ever touch a meaningful load. It's also why a casual five minutes on the bike before your heaviest sets is leaving performance on the table every single session.
Why It Gets More Important as You Age
In your twenties, the body is forgiving. You can walk in cold, push hard, and get away with it most of the time. What you're actually doing is using your first few working sets as a warm-up, which works until it doesn't.
As you age, the margin for error shrinks. The high-power muscle fibers you recruit for anything demanding take longer to activate. The nervous system requires more deliberate preparation to reach the same state of readiness. The joints need more time to move through their full range before you load them.
I've felt this shift myself. Twenty years ago I could handle almost anything with minimal preparation. Now, the warm-up is where I earn the workout. Sixty minutes for the Rogue Enduro wasn't excessive. It was the correct investment given the intensity of what followed.
What Most People Are Actually Doing
Walk in. Five minutes on the elliptical or assault bike. Maybe some shoulder circles. A couple of light sets of whatever the first exercise is. Go.
This gets you warm in a general sense, but it doesn't activate the specific movement patterns you're about to load. It doesn't prime the stabilizers that need to fire before the prime movers can do their job. It doesn't work through the ranges of motion that matter for that session. And it doesn't reach the intensity required to produce any real preparation effect.
If you're training seriously, a passive low-intensity shuffle before the session is physiological noise. It checks a psychological box without doing the actual work.
What Preparation Actually Looks Like
A proper warm-up builds progressively. You raise temperature gradually, work through the joint mobility patterns relevant to the session, activate the muscles you're about to load, and finish with movements that bring your nervous system to a high state of readiness for what's ahead. The whole sequence points toward the specific demands of the training session rather than functioning as a generic prelude to it.
The time required depends on the session. A moderate lifting day needs less than a maximal effort or competition. But the minimum effective dose is almost always longer than people think, and the quality of the movements matters more than the duration.
For competition or high-intensity testing, the window expands considerably. You're trying to walk into the first rep in the best physical state you can produce. That takes time.
With my online endurance clients, warm-up development is part of early programming. We build it, we test it across sessions, we refine it based on how they feel going into their work. Once we land on what works for that athlete, it becomes the race-day warm-up. We don't just use it on race day and hope for the best. We practice it. The warm-up itself gets trained.
Most people have never thought about preparation that way. They treat it as a formality rather than a skill. But if what you do before the session determines how well you perform during it, then the warm-up deserves the same intentionality as the training itself.
The Habit Nobody Builds Until They Have To
Most people don't develop a real warm-up practice until something goes wrong. An injury, a performance plateau, a session that felt inexplicably bad. Then they start paying attention to preparation and notice the difference immediately.
The people who train the longest and perform best across decades don't skip this step. They've learned what their bodies need before they can express what they're capable of. That's not a luxury. It's basic maintenance on the most complex performance system you'll ever use.
You're not too busy to warm up. You're too busy not to.
See you in the gym. —JG
