How to Warm Up Before a Workout: 5-Minute Routine

Your Warm-Up Has One Job

A warm-up isn’t a ritual or a flexibility routine. It has one job: take your body from “sitting at a desk” to “ready to produce force” without shocking it.

A good warm-up raises your core temperature, gets blood flowing to the muscles you’re about to use, rehearses the movement patterns of your workout, and gives your joints a chance to lubricate. Done right, it takes five minutes and makes your first working set feel better — and research consistently links warm-ups with a lower risk of strains when you’re about to load muscles hard.

Done wrong — usually as long static stretching in a cold body — it wastes ten minutes and can even temporarily reduce how much force your muscles can produce.

Static Stretching Before Exercise: Skip It

This is the single most common warm-up mistake. Holding long stretches on cold muscles:

• doesn’t prevent injury the way people assume
• can temporarily reduce strength and power output for the session
• eats your limited time without raising your temperature or rehearsing movements

Static stretching still has a place — after training, or on its own for flexibility goals. But it belongs at the end, not the start. We cover the timing question in detail in our guide on stretching before or after a workout.

Before training, you want the dynamic kind: moving through ranges of motion, not holding them.

The 5-Minute Warm-Up (Works Before Any Workout)

Three phases. Do them in order. No equipment, small space, works before running, lifting, cycling, or a class.

Phase 1: Raise the pulse — 2 minutes

• March in place with arm swings, building to a light jog in place — 60 seconds
• Jumping jacks (or step-jacks, low impact) — 60 seconds

You should end phase one breathing a little harder, warm at the collarbones, and definitely not gassed.

Phase 2: Wake up the joints — 2 minutes

• Hip circles — 10 per direction
• Leg swings — hold a wall, swing front-to-back 10 each leg
• Arm circles — 10 small, then 10 big, each direction
• Bodyweight squats — 10 slow, full-depth-as-possible
• Inchworm or cat-cow — 6 slow reps for the spine

Phase 3: Rehearse the first exercise — 1 minute

Do a lighter, easier version of whatever your workout starts with:

• Strength day? Two ramp-up sets of your first exercise — first with just the bar or bodyweight, then slightly heavier
• Running day? Three or four 10-second relaxed stride pickups before you settle into pace

That’s the whole routine: raise the pulse, move the joints, rehearse the movement. Five minutes, every time.

Adjust It to Your Workout

Workout type	Emphasize	Add before the first set
Upper-body strength	Arm circles, shoulder rolls, push-up plank hold	2 ramp-up sets of the first lift
Lower-body strength	Leg swings, hip circles, bodyweight squats	2 ramp-up sets, empty bar first
Running	Calves, ankles, hip openers	3 × 10s relaxed strides
Cycling / class	Easy 3–4 minutes at conversational pace	Usually nothing extra needed

Four Warm-Up Mistakes to Avoid

1. Static stretching cold muscles. Save it for after.
2. Skipping the warm-up when short on time. Cut a working set instead — the warm-up is what protects the sets you keep.
3. Turning it into a workout. If your warm-up leaves you tired, it was too much.
4. Same routine forever. If your squats feel stiff, add one extra hip move. Tune it to how your body feels that day.

Should You Foam Roll Before Exercise?

Light foam rolling can earn a place in phase two — but with two rules. First, keep it short: 30–60 seconds on a stiff spot (calves, quads, upper back), not a ten-minute full-body project. Second, it’s a “unlock the door” tool, not the event itself: roll, then move. Long rolling sessions belong after training or on rest days, which we cover in our complete foam rolling guide.

If you don’t own a foam roller, skip it entirely. The routine above works fine without one.

Morning vs. Evening Workouts: Does It Change Anything?

Yes — your body temperature changes the math. In the morning, your core is colder, joints are stiffer, and the pulse-raising phase matters more. Give phase one an extra minute and be generous with the joint work.

In the evening, you’ve been moving all day, so you can often compress the warm-up: shorter pulse-raiser, quicker rehearsal sets, and you’re ready. Either way, the same rule decides when you’re warm: when your first working set feels smooth instead of stiff, you’re there.

Where This Fits in Your Routine

A warm-up only works if there’s a workout to warm up for. If you haven’t built that yet, start with our guide on building a beginner workout routine — and make these five minutes the non-negotiable first block of every session.

Frequently Asked Questions

Is 5 minutes really enough warm-up?

For a general fitness session, yes. For very heavy lifting, a long run, or cold-weather training, extend phase one and add more ramp-up sets — total 8–10 minutes.

Should I stretch after my workout instead?

That’s a much better slot for it: your muscles are warm and time spent on flexibility then doesn’t interfere with strength. Keep the holds gentle, 20–30 seconds per position.

Does warming up prevent injury?

A proper warm-up is associated with fewer muscle strains when you suddenly load or sprint. It’s not a magic shield — sensible progression matters more — but it’s a cheap, five-minute insurance policy.

What if I’m sore — should I still warm up?

Yes, even more. A gentle warm-up typically makes mild soreness feel better by increasing blood flow. Just keep intensity low and see how the body responds as you go.

Can I just hop on a cardio machine to warm up for weights?

It covers phase one, but not the rest. Five minutes on a bike raises your temperature without rehearsing a single squat or press. Do the bike and the joint work — that’s the whole point of the three-phase structure.

How do I know when I’m warmed up enough?

Use the first-set test: when your first working set feels smooth and coordinated rather than stiff and rusty, you’re ready. If your joints still feel “rusty,” add another minute of the movement-specific phase — not more cardio.
