A good warm-up takes five minutes, not twenty, and it has almost nothing to do with touching your toes. The version that actually lowers your injury risk is simple: raise your body temperature, move your joints through their full range, and rehearse the movements you are about to do. Do those three things and you are warmed up. Everything else is optional.
Most people get this backwards. They walk into the gym, hold a few stretches for thirty seconds each, then wonder why their first heavy set still feels stiff. Static stretching has a place, but before a workout is not it: cold muscles stretched passively do not perform better, and may perform slightly worse for a short window afterward. Save the long holds for after you train, when your muscles are warm and the goal is to wind down.
Dynamic vs. Static: What Each One Is Actually For
Dynamic stretching means moving through a range of motion under your own control — leg swings, arm circles, walking lunges, hip openers. Muscles warm up because they are working, blood flow increases, and your nervous system starts firing the patterns you are about to use. Static stretching means holding a position still — a hamstring stretch, a quad pull, a seated forward fold. That is a cool-down tool: it tells the body to relax, which is the opposite of what you want two minutes before a squat or a run.
The practical rule is easy to remember: move before you train, hold after you train. If a stretch involves standing still and counting, it belongs at the end of the session. If it involves moving, it belongs at the start.
The 5-Minute Formula
Every solid warm-up follows the same three-part shape. First, spend about a minute raising your heart rate — a brisk walk, a slow jog in place, jumping jacks, or easy cycling. You are not trying to get tired; you want to feel slightly warmer and breathe a little harder than resting. Second, spend about two minutes on mobility for the joints the workout will stress: hips and ankles for lower-body days, shoulders and upper back for upper-body days. Third, spend about two minutes rehearsing the actual movements at low intensity — bodyweight squats before barbell squats, easy strides before a run.
The Lifting-Day Warm-Up
Do each move for about 30 seconds, moving continuously and keeping the effort easy:
- March in place or easy jumping jacks.
- Arm circles, small to large, both directions.
- Hip circles and leg swings, front-to-back and side-to-side.
- Bodyweight squats, slow and controlled.
- Cat-cow on all fours or standing spinal twists.
- Two light rehearsal sets of your first exercise — ten bodyweight squats before you load the bar, or easy push-ups before bench press.
The whole thing takes about five minutes. If your first exercise is a hinge like a deadlift, swap in easy hip hinges and glute bridges instead of squats. The principle stays the same: warm the joints you will use, then rehearse the pattern. If you follow a structured beginner program, pair this warm-up with our beginner strength-training guide and use the same five exercises as your rehearsal base.
The Running-Day Warm-Up
Running is repetitive, so the warm-up should wake up the hips, calves, and ankles, then ease into speed gradually:
- Two minutes of brisk walking, then one minute of very easy jogging.
- Leg swings, front-to-back and side-to-side, ten each side.
- Walking lunges with a gentle twist, about ten steps.
- Slow calf raises, ten reps.
- Two or three short strides: jog easy for 20 seconds, run a little faster for 10, then walk it out. These are not sprints — just a preview of faster running.
Then start your run slower than you plan to finish it. The first kilometre should feel almost too easy. Many running injuries trace back not to a missing stretch but to starting too fast on cold legs, especially after a rest day. If you are building up your running from scratch, this warm-up pairs naturally with our couch-to-running plan, which is built around the same idea: progress gradually, and let easy days stay easy.
What to Skip
A few warm-up habits do more harm than good. Holding a deep static stretch on a cold muscle before lifting or running is the biggest one — save it for after. Bouncing a stretch aggressively is another; it triggers a reflex that tightens the muscle you are trying to loosen. And foam rolling for fifteen minutes before every session is usually a time sink rather than a warm-up. A minute or two on a genuinely tight spot is fine, but rolling is not a substitute for moving.
Also skip the idea that you need a different warm-up every day. A routine you can do on autopilot beats a perfect routine you keep forgetting. Pick one lifting-day version and one running-day version and use them for a month.
When Five Minutes Is Not Enough
Five minutes covers a normal session in normal conditions. Take a little longer — up to ten minutes — when it is cold outside, when you are training early in the morning, or when you are returning from a break. Older lifters and runners also tend to need a longer ramp-up, and that is normal, not a weakness. The test is simple: if your first working set or first kilometre still feels stiff and uncoordinated, your warm-up was too short or too generic. Add another minute of general movement and another rehearsal set next time.
On the other hand, if your warm-up leaves you breathing hard or your legs tired before the workout starts, you overdid it. A warm-up should leave you ready, not worked.
Where Stretching Still Belongs
None of this means stretching is useless — far from it. After a workout, when muscles are warm, a few minutes of gentle static stretching or a short mobility routine helps you wind down and can ease next-day stiffness. A simple daily routine works well here: our morning stretch routine for stiff bodies doubles as a solid post-workout cool-down. The point is timing, not whether stretching itself is good or bad. Move first, hold later.
Five minutes is a small price for a session that feels better from the first rep. Warm up the same way every time, rehearse what you are about to do, and save long stretches for the end.
