I have watched a lot of people arrive for a session, put their bag down, and go straight into the first exercise. They are not being lazy. The warm-up just feels like nothing is happening. Ten minutes of easy movement when you only have an hour, and you want to get on with the bit that counts.
The problem is that the warm-up is the bit that counts. Skip it often enough and it will catch up with you, usually in the form of a tweaked hamstring or a lower back that “just went” picking up a kettlebell.
What a warm-up actually does
Three things, mostly.
It raises your body temperature. Warm muscle stretches and contracts more easily than cold muscle. That sounds obvious, but it is the main reason a warm-up cuts the chance of pulling something. Your tissues are simply more forgiving when they are warm.
It wakes up the right muscles. If you have spent the day sitting at a desk in Salford or driving between jobs around Bury, your glutes and the muscles around your hips have been switched off for hours. Ask them to do a heavy squat with no notice and other muscles step in to cover, usually your lower back. A few minutes of targeted movement gets the right muscles doing the job.
It gets your joints moving through their full range. Ankles, hips, upper back, shoulders. Most of the aches people in their 40s and 50s put down to age are really just joints that have not been taken through their full range in a long time.
The research backs this up. A 2026 systematic review looking at warm-up strategies found they were consistently linked to a lower risk of lower body injuries, alongside better performance in things like sprinting and jumping. It is not a guarantee. Nothing in training is. But the weight of evidence sits firmly on the side of doing it.
Why it matters more the older you get
At 22 you can get away with a lot. Your tissues recover fast and your joints have not yet accumulated years of sitting, driving and carrying shopping in one hand.
After 35 or so that changes. Connective tissue gets stiffer. Recovery slows down. The gap between “cold and stiff” and “warm and ready” widens, and the cost of skipping that gap goes up. Most of the injuries I see in clients across Prestwich and Whitefield are not dramatic. They are small strains that happened in the first five minutes of a session, doing something the person had done a hundred times before.
What a warm-up is not
It is not static stretching. Standing still and holding a hamstring stretch for 30 seconds before you train does not prepare you for anything, and there is decent evidence it can temporarily reduce the force your muscles produce. Save the long holds for after the session or for a separate stretching day.
It is not a five minute walk on the treadmill while you look at your phone. That raises your temperature a bit, but it does nothing for the joints and muscles you are about to use.
And it is not a workout in itself. If you are out of breath and sweating heavily before you have touched a weight, you have gone too hard.
The ten minute version
This is roughly what I use with clients. It follows a structure coaches call RAMP: raise, activate, mobilise, potentiate. You do not need to remember the name. You need to remember the order.
Minutes 1 to 3: raise
Easy movement to get warm. A brisk walk, a gentle jog on the spot, skipping if you have a rope, or a few rounds of marching with high knees. You should feel warmer and your breathing should pick up slightly. That is all.
Minutes 3 to 6: activate
Switch on the muscles that tend to go quiet. Glute bridges, ten slow reps. Bodyweight squats to a chair, ten reps, pausing at the bottom. A short plank, 20 to 30 seconds. If you have a resistance band, side steps with the band around your knees are excellent for waking up the hips.
Minutes 6 to 9: mobilise
Take your joints through their range. Leg swings forward and back, holding onto a wall, ten each side. Hip circles. Arm circles, small to large. A few “world’s greatest stretch” reps, which is a deep lunge with a reach up towards the ceiling. Cat and cow on the floor if your back feels tight.
Minutes 9 to 10: potentiate
One or two things that look like what you are about to do, done a bit lighter. If you are squatting, a set of squats with just the bar or a light kettlebell. If you are running, a couple of short pick-ups where you run faster for 20 seconds and ease off. This tells your nervous system what is coming.
That is it. Ten minutes. If you only have five, do minutes 1 to 3 and then a shortened version of the rest. Something is much better than nothing.
The honest reason people skip it
It is boring. There is no getting round that. A warm-up does not make you feel like you have achieved anything, and if you are training on your own with limited motivation, boring things are the first to go.
Two things help. The first is to stop thinking of the warm-up as separate from the session. It is the first ten minutes of the session. You would not skip the first ten minutes of a film.
The second is to have someone else in charge of it. This is a big part of what a personal trainer does. Not shouting at you, just taking the decisions out of your hands so that the boring but important things happen automatically.
If you want a hand with this
I run mobile personal training across Prestwich, Whitefield, Bury, Radcliffe and out towards Salford, Swinton and Worsley. Every session starts with a proper warm-up built around what your body needs that day. If that sounds useful, book a free consultation and we can talk about where you are starting from.
