Workout Wednesday: Why Your Warm Up Matters More Than You Think

Let me be honest with you right off the bat.

I probably do less warming up than I should. I know it is beneficial. I know it helps prevent injury. I still sometimes skip parts of it when I am running short on time or just want to get into the actual lifting.

So I am not going to stand here and lecture you. I am going to tell you what warming up actually does, what my routine looks like, and why the days I actually do it properly always feel better than the days I do not.

What Warming Up Actually Does to Your Body

Before we get into the how, it is worth understanding the why. And the science here is actually pretty compelling.

When you warm up before lifting, a few things happen simultaneously.

Your muscle temperature rises. Warming up significantly improves muscle performance, particularly speed and power, by increasing muscle temperature. Warmer muscles are more pliable, more efficient, and better able to handle the demands of heavy lifting.

Blood flow to the muscles increases. More blood means more oxygen and more nutrients being delivered to the muscles you are about to use. They are better fueled before you even touch the bar.

Your nervous system activates. Warming up increases muscle temperature, blood flow, and neural drive, which all improve coordination, reaction time, and movement efficiency.</cite> In plain terms, your brain to muscle communication works better when you are warmed up. Your body moves more efficiently and safely.

Your awareness improves. As you begin moving, you may notice tight areas, minor discomfort, or muscle fatigue that could influence how you structure your workout. This awareness allows you to adjust your plan if necessary, preventing the possibility of pushing too hard when your body may not be ready for certain exercises.

With the right warm up, you are faster, stronger, more powerful, have better reaction time, are able to work out longer, and it reduces your risk of injury. If you could bottle that and sell it, everyone would buy it. The fact that it is free and just requires a few minutes is either the best kept secret in fitness or the most ignored one.

Dynamic vs Static Stretching: Get This Right

Most people have this backwards.

Static stretching, the kind where you hold a position for thirty seconds, is better suited for after your workout when the muscles are already warm and pliable. Doing static stretches on cold muscles before a lift is not as effective and can actually reduce power output temporarily.

Dynamic stretching is what you want before you lift. These are movement based stretches. Think arm circles, leg swings, hip rotations, bodyweight squats. They move the joints through their full range of motion, get the blood flowing, and prepare the muscles for what is coming without the downsides of holding static positions cold.

A quick Google search for dynamic stretches for whatever body part you are training that day will give you plenty of options. Experiment and find what feels good for your body.

My Actual Warm Up Routine

Since I go to the gym first thing in the morning, waking the body up before attempting to lift heavy weight is pretty important. Trying to squat heavy when you are half asleep is a bad idea. Stating the obvious but worth saying.

Here is what I actually do.

I start with a foam roller. I roll out my back and whatever muscle groups I am training that day. It cracks my back and for some weird reason I love that. Beyond the satisfaction of the crack, foam rolling helps loosen up tight areas and improve blood flow before you even start moving.

Then some dynamic stretching. Arm circles, leg swings, hip openers, whatever is relevant to the day's workout. This takes maybe two to three minutes.

Then one or two warm up sets before my first working set.

Warm Up Sets: The Most Underrated Part

Warm up sets are sets of your first exercise done with a significantly lighter weight than you plan to work with.

The goal is not to fatigue yourself. It is to remind your body what the movement is supposed to feel like. You go slow, get a full stretch at the bottom, squeeze at the top, and focus entirely on the range of motion rather than the weight.

This does two things. First, it warms the specific muscles you are about to use so that when the real weight goes on it is not the first stress they have experienced. Second, it helps you remember the correct form for the lift before the weight gets heavy enough that bad habits can creep in.

I have forgotten to do warm up sets before and immediately noticed the difference. The first few reps with the working weight feel off. The range of motion is not quite right. The muscle does not feel engaged the way it should. A couple of light sets fixes all of that in about ninety seconds.

Compound Lifts Need More Warm Up

Not all exercises require the same level of warm up.

For big compound movements like squats, deadlifts, and bench press, you want to be properly warmed up before you load the bar. These lifts stress your muscles, joints, and ligaments throughout your entire body simultaneously. The more stress involved, the more important it is to be ready for it.

For smaller isolation exercises like bicep curls or tricep pushdowns, a warm up is still helpful but the stakes are lower. You are working a smaller muscle group with less total load.

The general principle is simple. The heavier and more complex the movement, the more thorough your warm up should be.

What About Cardio as a Warm Up

I like to do a few minutes of light cardio before lifting. Treadmill, bike, whatever is available.

I would not call it strictly necessary the way stretching and warm up sets are. But it helps get the body moving, gets a light sweat going, and signals to the brain that exercise is happening before the heavier stuff begins. It also helps with getting in the mood to actually train, which is not nothing at five thirty in the morning.

If you find a few minutes of cardio before lifting helpful, do it. If it feels like a waste of time, skip it and focus on the stretching and warm up sets instead.

What Happens If You Skip It Consistently

When I was young I never warmed up. I was made of rubber bands and nothing could kill me.

Over time that changed. I started noticing more stiffness. More aches and pains that were not the satisfying kind of muscle soreness but the more concerning kind. Joint discomfort. Lower back tightness. The kind of things that do not always go away quickly.

Adding stretching and warming up to my routine consistently helped knock the cobwebs off and made those issues significantly more manageable.

Skipping warm ups consistently over a long period of time leads to those compounding aches and pains. Not always immediately. But over months and years your body keeps score.

How Long Should a Warm Up Take

Honestly somewhere between three and ten minutes depending on the person.

I am usually done in about three minutes between some brief stretching and a couple of warm up sets. Maybe I am an idiot and my limbs are all going to pop off next time I go to lift, but until then this seems to work for me.

Younger people with naturally good flexibility might need less time. Older lifters or people who are naturally stiff might need more. The point is not to hit a specific time target but to feel ready. When you feel loose, aware of your body, and mentally prepared for the work ahead, you are warmed up enough.

Do not rush it. But do not turn it into a forty minute production either.

The Bottom Line

Warming up is not sexy. It is not the part of the gym session where people look over and think wow who is that. Nobody posts their warm up sets on Instagram.

But it will help you perform better, feel better during your workout, and protect you from the kind of injuries that keep you out of the gym for weeks at a time.

Try adding five minutes of dynamic stretching and one or two warm up sets before your next session. Then tell me I am full of it.

But seriously. It will help.

We are the underdogs. We don't stay down, we bite back.
