5 Warm-Up Mistakes That Increase Your Injury Risk

TL;DR

The five most common warm up mistakes are jogging a lap alone, walking before a run without activating your muscles, static stretching only, skipping the shoulders, and using the same routine for every sport. Each one leaves a muscle group unprepared for load. Change one mistake at a time, not your whole routine.

In Detail
Warm-up mistakes are one of the easiest things to fix before they turn into an injury, yet they are still common even among experienced players. Most of these mistakes come from habit, not a lack of effort. Winter makes these mistakes more costly, since cold muscles need more preparation than warm ones. In this post, you will learn the five warm-up mistakes physios see most often, and what to do instead.

1. Jogging a lap and calling it done
A slow jog raises your heart rate a little, but it loads your muscles in much the same way as the run itself, just at a lower intensity. That means you are still absorbing impact through a running movement, rather than activating individual muscles in a controlled way before you need them. This is true even if your normal running pace is already slow. A jog does not count as a proper warm-up just because it is easier than your usual run.

2. Walking before a run, then running straight into it
Walking a kilometre before a run is a reasonable start for your ankles, but it does not activate your quads, glutes or calves. It doesn't matter whether you then sprint or ease into an easy jog; those muscles still need to be switched on deliberately before they are asked to absorb the impact of running.

3. Static stretching only, before activity
Holding a stretch still for 20 to 30 seconds feels productive, but done cold, before sport, it does not activate the muscles you are about to use. Save longer static stretches for after the activity instead.

4. Skipping the shoulders
Not every sport needs a dedicated shoulder warm-up, but more do than people expect. Throwing sports and swimming are the obvious ones, but sports like netball also load the shoulder heavily through passing and shooting, and players often skip warming it up regardless. Shoulder warm-ups are also often reduced to a few arm swings, which move the joint but do not activate the muscles around it. Purposeful movements, like squeezing your shoulder blades back and holding, do more to prepare the shoulder for load.

5. Doing the same generic routine regardless of sport
A warm-up built for running is not the same as one built for a sport with quick changes of direction, like netball or rugby. Higher-level teams tend to tailor their warm-up to their sport, while recreational players are more likely to use the same routine regardless of what they are about to play.

How to choose the right fix
Start by looking at whichever mistake sounds most like your current routine, and change one thing at a time. Adding a single low level strength movement per muscle group, alongside your existing joint movement, closes most of the gap without needing a full programme overhaul.

What to do next

• Add one low level strength exercise per major muscle group to your warm-up.
• Save static stretching for after activity, not before.
• Match your warm-up to the specific demands of your sport.
