Warm Ups Should Warm You Up

Warm Ups Should Warm You Up


You walk into the gym with a workout plan in mind and feel you should “warm up” first but what should you do and what is meant by “warming up”?


As a Personal Trainer I spend a lots of time in the gym and this gives me the opportunity to observe many different types of people and other Personal Trainers. What I see appears to be wildly varying approaches to warm ups. Many of which are poorly chosen for the workout at hand.


The three most common types are:


1) The cardio machine 10 minute standard

2) The mini triathlon where a person moves between three different pieces of cardio equipment for about 5 minutes on each

3) The “I must sweat” warm up


Number one can be a good thing if you find you need that long to get your self in the mood mentally.

Number two screams of lack of knowing what a trainee wants to do for the day and feels they must somehow use every piece of equipment in the gym. Thumbs down.

Number three is just plain stupid. A warm up should never leave you fatigued in any way. Ever.


A warm up should do just that, warm you up, slightly. A physical change in the temperature of your muscles. It is the portion of a workout where you are checking to make sure all your muscles and joints feel OK for the day and you have no niggling aches or pains. It is not the place to be breathing heavy or sweating, that would indicate fatigue. Fatigue at this stage is bad.

Over the years as a Personal Trainer (I’m based in Epsom and work in and around London and Surrey FYI) I have determined that flexibility and mobility work, where necessary, should be carried out at the end of a workout when your muscles and joints are fully lubricated, warm and relaxed.

What do I mean by “If it is necessary”?

Flexibility and mobility work need only be carried out, in my experience, if a person is lacking in the basic functional requirements of a joint or muscle or if a specific movement pattern is suffering due to inflexibility or immobility and occasionally  if pain is present in a joint e.g. lower back pain can sometimes be alleviated when hip flexor muscles are stretched.

Back to the warm up…

A warm up should be specific to the workout

Running today in your workout? Then your warm up should be based around running, for example:

If one of my Personal Training clients is due into the Epsom studio today and has a 10k run planned as part of a long term program I would have them start with a walk for a few minutes which will progressively turn into a jog and then a few minutes of light running. Nothing fancy, no foam rolling or long winded mobility drills, no sweating or panting and no stretching, yet.

If a Personal Training client is due a deadlift session then I will not have the perform the same warm up as above. I’ll have them work deadlift with an empty bar for a set or three or five (depending on how things look and feel for them) an then we’ll work our way up slowly to a working weight. For example:

Let us assume a working weight of 160kg

Set one – 20kg bar x 10 -15 reps

two – 60kg x 5-8 reps

three 80kg x 3-5 reps

four 100kg x 1 rep

five 120kg x 1 rep

six 140 x 1 rep

seven 160 x X reps…..

Same goes for a squat…I’d have them squat to warm up for the squat. Slowly.

Kick boxing? Yup, I have them perform light practice reps of kicks, knees, punches and elbows and build up the intensity as the session moves along.

Getting the picture? Warm up what you are working.

Different people warm up at different rates

This is where experience as a trainer comes in or just knowing your own body.

Some people will warm up faster than others. Many factors can affect this but experience shows that the main factor is fibre types.

Some people have a high percentage of slow twitch muscle fibres (we all have all three main fibre types but in different ratios) that produce less force, use less fuel and are more efficient at dissipating heat with a better blood supply. These people require and desire longer warm up periods.

Others may have a higher percentage of fast twitch muscle fibres and these generate more force, faster and have a lesser blood supply so tend to heat up faster and cool off more slowly. Warm ups should be kept minimal here.

Slow Twitch or Fast Twitch?

Slow Twitch or Fast Twitch?

Knowing which type you are can be both complicated and simple, huh? I know, bear with me. 

Some people just know they are better than average at certain events; always been good at long distance swimming but crap at sprints? Probably fair to say you have a good percentage of slow twitch fibres (type 1 muscle fibres).

Have you always been a superb jumper, thrower or sprinter? Probably pretty safe bet to say you have a high percentage of fast twitch fibres (type 2 muscle fibres)

Yes this is a very VERY simplified break down but it’s a good place to start and if you want to delve deeper then I suggest you find your self a well educated Personal Trainer.

I have not seen many people speak of the different warm up procedures that need to be applied to different fibre types as it is a field not really explored too deeply yet but it will be. Eyes open. 


Take home message:

  • Warm up with the movements that you have planned in your workout for the day
  • Do not tire yourself out in the warm up
  • Only work flexibility and mobility at the end of a workout, if you need to



if your warm up leaves you with fatigue that detracts from your workout performance then you have gone too far
