How to Warm Up Before Lifting (Without Wasting Time)

A good warm-up makes your first working set feel better and reduces your injury risk. A bad warm-up wastes 20 minutes on a foam roller while your body is still cold. Here's how to warm up efficiently so you can get to the real work.

Why warming up matters

Cold muscles don't perform well. When you warm up, you increase blood flow to the muscles you're about to use, raise your core temperature, and prime your nervous system for heavy loads. The result: your working sets feel smoother, you can lift more, and you're less likely to pull something.

Skipping the warm-up entirely is a gamble. It might be fine for a while, but the one time it isn't, you lose weeks to an injury that was completely preventable.

What to skip

  • Long cardio sessions. Ten minutes on the bike before squatting is unnecessary. You're not training for a triathlon — you're trying to get warm.
  • Static stretching. Holding a stretch for 30–60 seconds before lifting can temporarily reduce force output. Save static stretching for after your session or on rest days.
  • Foam rolling everything. A few minutes on a problem area is fine. Rolling every muscle group for 20 minutes is procrastination with extra steps.

What to do instead

Step 1: General warm-up (2–3 minutes)

Get your heart rate up and break a light sweat. Anything works:

  • Brisk walk or light jog
  • Jumping jacks
  • Rowing machine at an easy pace
  • Skipping rope

You're not trying to exhaust yourself. Just get warm.

Step 2: Dynamic stretches (2–3 minutes)

Move through ranges of motion you'll use in the session. Pick 3–4 that match your workout:

  • Leg swings (front-to-back and side-to-side) — before squats or deadlifts
  • Hip circles — before any lower body work
  • Arm circles and band pull-aparts — before pressing or pulling
  • Cat-cow or thoracic rotations — before overhead pressing
  • Bodyweight squats or lunges — before leg day

Do 10–15 reps of each. Keep it moving.

Step 3: Ramp-up sets (3–5 minutes)

This is the most important part. Before your first working set of each compound lift, do 2–4 progressively heavier sets:

Example for a working set of 100 kg squat:

  1. Empty bar (20 kg) × 10 reps
  2. 60 kg × 5 reps
  3. 80 kg × 3 reps
  4. 90 kg × 1–2 reps
  5. First working set: 100 kg

Ramp-up sets let you practise the movement pattern, feel out how your body is responding that day, and gradually load the joints and tendons. Don't skip these — they're not wasted sets.

For isolation exercises (curls, lateral raises, etc.), one lighter set before your working weight is usually enough.

Put it together

A complete warm-up for a squat-focused session might look like:

  1. 2 minutes on the rower
  2. Leg swings, hip circles, bodyweight squats (1–2 minutes)
  3. Ramp-up sets: bar × 10, 60 × 5, 80 × 3, 90 × 1
  4. Working sets begin

Total time: under 10 minutes. That's all you need.

Track your ramp-up sets too

Logging your warm-up weights might seem unnecessary, but it creates a useful record. If you notice your ramp-up sets feeling heavier than usual, it's a sign you might need to adjust your working weight or take a deload. A good workout tracker makes this easy — just log the sets as you go.
