A beginner's gym warm-up: what to do in the first ten minutes

You have changed, you are standing somewhere between the treadmills and the squat racks, and you have no idea what to do before your first set. Ten minutes covers it, as long as you split them into three steps and run them in the same order every session. Here is what that looks like, with actual numbers.

What a warm-up actually does

Easy movement raises muscle temperature, lifts your heart rate and breathing, and pushes more blood into the muscles you are about to load. Joints move more freely, muscles contract and relax a little faster, and your nervous system gets a rehearsal of the pattern that follows.

The evidence is strongest for performance: most people lift more, and lift more tidily, on the first working set if a few lighter sets came before it. For injury prevention the picture is murkier, and most of what exists comes from running and change-of-direction sports rather than from lifting.

So treat the warm-up as preparation for a better session, not as insurance. If this is your first or second visit, it also helps to know how a full session runs from start to finish, so you are not wandering the floor between sets.

Minutes 0 to 5: get warm

The first five minutes are easy cardio. A stationary bike, a rower, a cross trainer or brisk walking on a slight incline all do the same job, so pick whichever bores you least.

Keep the effort at 3 or 4 out of 10: you should be able to talk in full sentences and you should not be puffing. You are done when your forehead is faintly damp and your hands and feet no longer feel cold. In a cold gym in January, stretch it to seven minutes.

This is not conditioning and it should not tire you. Heavy legs after five minutes on the bike mean you went too hard. Drink 200 to 300 ml of water while you are there; how much you actually need around training depends on the length of the session and the room, but starting thirsty is never useful.

Minutes 5 to 8: move, do not hold

The next three minutes go on movement rather than positions. Eight to ten reps per drill, controlled, no bouncing and nothing that hurts.

A short list that covers most sessions: 10 bodyweight squats to a comfortable depth, 8 leg swings forwards and back per side, 10 band pull-aparts, 8 thoracic rotations per side and 10 calf raises.

Save long static stretching for the end of the session. Holds beyond 30 to 60 seconds per muscle, taken right before heavy sets, can dent your strength for a while and add nothing a warm-up needs. Brief 10 to 15 second holds, if you like them, are harmless.

Minutes 8 to 10: ramp-up sets

The last two minutes matter most, and they are the part beginners skip. Ramp-up sets belong to the first and heaviest exercise of the day, and they use that exact movement, not a substitute.

Say your working weight on the bench is 60 kg for 8 reps. The run-up looks like this: empty bar for 10, 30 kg for 5, 45 kg for 3, 55 kg for 1 or 2, then the first working set. Rest 30 to 60 seconds between them, enough to shed fatigue and not enough to cool down.

Those sets do a second job: they tell you whether today's working weight is honest. If 55 kg for a single feels heavy, work at 55 instead. There is more detail in the pieces on picking the weight for your first set and working out what to load on the bar.

For the second and third exercise of the session, one lighter set is usually plenty, and on machines you can often skip it altogether.

Three ten-minute examples

Leg day

Five minutes on the bike, then 10 bodyweight squats, 8 leg swings per side and 10 split squats on the spot. Then the squat: empty bar for 10, followed by two or three ramp-up sets to your working weight.

Upper body

Five minutes on the rower or cross trainer, then 10 band pull-aparts, 10 backward shoulder circles and 8 press-ups with your hands on a bench. Then the press, starting with the empty bar.

Full body

Five minutes of brisk walking at a 5 to 8 per cent incline, then 10 bodyweight squats, 10 band pull-aparts and 8 deadlifts with the empty bar. Then straight into the first lift of the plan.

When to see a doctor

The warm-up doubles as a check. Chest pain or pressure, dizziness, feeling faint, or breathlessness out of proportion to easy pedalling are reasons to stop the session and speak to a doctor rather than push on.

The same goes for sharp joint pain that has not settled after ten minutes of movement, for swelling, and for pain that wakes you at night. If you have known heart trouble, high blood pressure, or a recent injury or operation, get medical advice before you start lifting. A dull, even stiffness that fades as you warm up is a different thing and is usually nothing.

The short version

• Five minutes of easy cardio at 3 to 4 out of 10, until you are faintly sweaty.
• Three minutes of movement drills, 8 to 10 reps each, and no long static stretches.
• Two minutes of ramp-up sets on the first lift: empty bar, then roughly 50, 70 and 85 per cent of the working weight.
• Rest 30 to 60 seconds between ramp-up sets; one light set is enough for accessories and machines.
• Chest pain, dizziness or sharp joint pain means stop and get it checked, not push through.
