When it comes to exercise and nutrition advice, there’s all kinds of information floating around. Some of it is science-backed, some comes from personal experience, and some… well, it’s just plain misinformation.

I once had someone tell me you should warm up for the number of minutes equal to your age. So if you’re 40 years old, that means 40 minutes of warming up. Now, maybe that makes sense before a big athletic event or a race, but let’s be honest—that’s not realistic for the average Joe walking into the gym on a Monday morning.

Still, there’s a kernel of truth hidden there: warming up really does matter. In fact, skipping your warmup is like trying to drive your car on a freezing morning without letting the engine run first. It’s not just uncomfortable, it’s risky.

A proper warmup does far more than get you sweaty. It prepares your body—and your mind—for the work ahead. According to strength coaches and performance experts, the right kind of warmup increases blood flow, raises your core temperature, and wakes up your nervous system. That means your muscles contract faster, your joints move more smoothly, and your brain is primed to perform.

Think about it: would you expect to sprint at top speed right after rolling out of bed? Of course not. Yet that’s what many of us do when we skip the warmup and dive headfirst into exercise.

The best warmups aren’t about endless jogging or holding long stretches. In fact, research shows those approaches don’t do much to improve performance. Instead, a good warmup should:

• Increase your heart rate gradually to get the blood flowing.
  
• Mobilize key joints like hips, shoulders, and ankles that tighten up from sitting all day.
  
• Activate specific muscles so they’re firing before you start lifting, running, or playing.
  
• Prime your nervous system with dynamic, explosive movements that wake up your coordination.
  

And here’s the good news: this doesn’t take long. In just five to ten minutes, you can run through simple drills—lunges, hip openers, band pull-aparts, or short sprints—and suddenly your body is ready. You’ll feel lighter, looser, and more athletic before the “real workout” even begins.

Skipping this step might save you time in the short run, but it often leads to poor performance—or worse, injury. Tight hamstrings, stiff shoulders, or a cold back aren’t just uncomfortable—they’re ticking time bombs once you load up the bar or push the pace.

So next time you’re tempted to breeze past the warmup, remember: those first few minutes aren’t throwaway time. They’re the foundation for everything else. Treat your warmup like an investment, and your workout (and body) will pay you back in strength, longevity, and fewer injuries.

Warmups aren’t busywork. They’re smart work. And if you want to perform at your best, they’re non-negotiable.
