How to warm up before lifting

A proper pre-lifting warm-up has three parts: 5–10 minutes of light general cardio, 2–4 minutes of dynamic mobility for the muscles you’re about to train, and a few progressively heavier warm-up sets on your first compound lift. The whole routine takes 10–15 minutes, lowers injury risk, and makes your first working set feel like an actual working set instead of a slightly panicked first rep.

That’s the short version. The rest of this post is what each part looks like in practice, why it matters, and the mistakes that turn warm-ups into either wasted time or skipped time.

Why warm up at all?

Walking up to a heavy barbell with cold joints, tight hips, and a quiet nervous system is a fast track to a sketchy rep. A warm-up does three specific things:

Raises muscle and joint temperature so tissue moves more freely
Mobilizes the connective tissue you’re about to load
Primes the nervous system so the first heavy effort doesn’t feel like a near-miss

Skipping the warm-up doesn’t make you tougher. It just means your first working set is your warm-up — and the form usually shows it.

Part 1: General warm-up (5–10 minutes)

The goal is a light sweat and elevated heart rate, not a workout in itself.

Options:

Treadmill, bike, or rower at an easy conversational pace
Brisk walking with arm swings
A few minutes of jump rope if your gym has space

Aim for “I’m warm, not tired.” If you’re winded before you’ve touched a weight, you went too hard.

Part 2: Dynamic mobility (2–4 minutes)

Static stretching before lifting — holding a stretch for 30+ seconds — measurably reduces strength output for the next hour. Dynamic mobility is different: you move through the range of motion you’re about to use instead of holding it.

Pick two or three movements that match the day’s training:

Lower-body day:

Bodyweight squats — 8–10 reps, going progressively deeper
Hip circles or the world’s greatest stretch — 5 per side
Glute bridges — 10 reps

Upper-body day:

Arm circles forward and backward — 10 each direction
Band pull-aparts — 15 reps
Scapular wall slides — 8–10 reps

Pressing days specifically: spend an extra minute on the shoulders. Loaded scapular work or face-pulls with a light band go a long way toward keeping your bench pain-free.

Keep this brief. It’s preparation, not training.

Part 3: Exercise-specific warm-up sets

This is where most lifters either skip work they need or do twice as much as required. The general rule: warm up enough that your first working set feels like an actual working set, not a survival effort.

A workable ramping setup for a moderately heavy compound — say, a 100 kg / 220 lb back squat working weight:

Empty bar × 8 — groove the pattern
40% × 5 — light, smooth, fast bar speed
60% × 3 — moderate, still fast
80% × 1–2 — neural primer, no fatigue
First working set

For lighter accessory exercises — curls, lateral raises, leg curls — one warm-up set at roughly 50–60% of your working weight is plenty.

A 10-minute sample routine

The full thing, end to end:

Min 0–5: Easy bike or treadmill, conversational pace
Min 5–8: Two or three dynamic mobility moves matching the day’s training
Min 8–13: Exercise-specific warm-up sets on your first compound

If your gym is cold, lean toward 10 minutes of general work. If it’s warm and you walked or biked in, 5 minutes is often enough.

Common mistakes

Static stretching as a warm-up. Long static holds before lifting reduce strength output. Save those for after the workout or a separate mobility session.

Skipping the general warm-up. Going straight to bar work means your first warm-up set is also your tissue warm-up. Early sets feel sluggish and form drifts.

Doing too many warm-up sets. More than four or five ramping sets on a heavy compound usually means you’re depositing fatigue before the working sets. Stop adding warm-up reps once the bar moves fast and the position feels locked in.

Treating the warm-up as a separate session. A warm-up is 10–15 minutes. If you’re routinely spending 25 minutes “warming up” before your first working set, you’ve drifted into either training or stalling.

Make it boring, then forget about it

Once you have a warm-up that works, it stops needing thought. Same general warm-up, same handful of mobility moves, same ramping scheme on the first lift of the day. The point isn’t to optimize the warm-up — it’s to make the first working set feel like a working set.

In Steady, you log what counts. Most lifters skip logging warm-up sets entirely, so the training history reflects real working effort and progressive overload tracks cleanly across sessions. Open the app, hit the first working set, get to work.
