Warm-up: the part everyone skips

Warm-up decides more about how a session feels than the implement, the position or the strength of anybody's arm. It is also the first thing people cut when they are nervous or in a hurry, which is why so many first attempts end at twenty minutes with everyone disappointed.

If I could give someone one piece of technique, from either end, it would be this one. Everything else on this site is refinement. This is the lever.

The reason it gets skipped is obvious enough. It is the least dramatic part of the evening, both people are nervous, and the thing they have actually been thinking about for weeks is not this.

So a top who is unsure of himself gets through the boring bit quickly to reach the part he thinks he is being judged on, and a receiver who is embarrassed does not want to say that the hand feels nice and she would like ten more minutes of it. Between them they remove the foundation and then wonder why the building falls over.

Cold skin cannot take what warm skin can

The same stroke, delivered in the first minute, can be genuinely unbearable. Twenty minutes into a properly built session it can be barely noticeable. That is not bravery and it is not a change of attitude. It is the same arm doing the same thing to a different body.

Part of it is the tissue. Warm, well supplied tissue absorbs and spreads impact in a way that cold tissue does not, and the usual explanations involve local blood flow and the body's own opioid response. I would not want to defend the physiology in any detail and I distrust anyone who claims to be able to. The effect is obvious to anyone who has done this twice, whatever the mechanism turns out to be.

The other part is the bracing, and I think it matters at least as much. A cold start makes people clench. They hold their breath, lock the muscle, and tense into every stroke, which is the worst possible way to receive one.

Impact lands on rigid muscle instead of spreading through relaxed muscle, and the body treats each stroke as an ambush rather than as the next beat of something it already understands. Ten minutes of gentle rhythm gets a person out of that state. Nothing else does.

The shape of a proper warm-up

Hand first, always. Nothing else gives the person swinging it any information about what is happening to the skin, and nothing else has a governor built in.

Light and fast, not slow and hard. This is the bit people get backwards. At the start you want a quick rhythm with very little force behind each contact, covering the whole surface rather than working one spot. You are building heat, not making a point. Slow, deliberate, heavy strokes belong later, when the pause between them is doing something.

Every new implement gets its own small warm-up. Not the full fifteen minutes, but a dozen light strokes to calibrate distance and angle before anything committed. The body is warm by then. Your aim with that particular object is not.

How long is realistic

Ten to twenty minutes with someone you know. Longer with someone new, longer if the room is cold, longer if either of you is wound up about something that happened earlier in the day.

The way I think about it is proportion rather than minutes. The warm-up is the first third of the scene. If you have an hour, that is twenty minutes of it, and the twenty minutes are not a preamble to the session. They are the session for a while. Receivers routinely tell me afterwards that the early part was the best bit, and then look slightly ashamed of saying so.

What happens when you skip it

The failure is predictable enough that I can describe it in order.

The first hard stroke lands on a cold, tense body and hurts far more than either person expected. The receiver flinches and tightens. The next one lands on tighter muscle, so it hurts more again, so she tightens further. Breathing goes shallow or stops. She starts moving away from the strokes, which spoils aim and produces one that lands somewhere unintended, which frightens both of you. Tolerance, which might have been fine, collapses to almost nothing inside five minutes.

Then one of two things. Either she safe words at ten minutes and feels like a failure, which she is not, or she says nothing, endures it, and goes home having had a bad evening she will describe as fine. The second is worse. It is also more common, because a person who has waited years to try this is highly motivated not to be the one who ruined it.

Reading when someone is ready

This is the top-side skill and it takes a while to learn. You are looking for a body that has stopped defending itself.

• Skin. Evenly pink and warm across the whole area rather than blotchy or patchy in the spots you have favoured. Warmth you can feel through the back of your hand, not just colour.
• Breathing. It deepens and slows once someone settles. The sharp intake before each stroke turns into something longer and more even, and the sound of it changes.
• Weight. A braced person holds themselves up. A settled person has let their weight go into the bed, the chair or your leg, and you can feel the moment that happens.
• Hands and feet. Fists unclench. Feet stop shifting for grip. Someone whose toes are still gripping the carpet has not arrived yet.

There is also a change in quality that is hard to write down and unmistakable in the room, where the person stops being a nervous adult and becomes quiet and heavy and slightly elsewhere. That is the point at which you can start doing something more interesting. More on those signals at reading your partner.

Re-warming

Heat leaves faster than people think. If you have stopped for ten minutes to talk, make tea, or deal with a phone, you do not pick up where you left off. You go back to your hand for a couple of minutes first.

The same applies after a change of position, since the target area shifts and part of what is now presented has had nothing done to it. And it applies in a cold room, in which case fix the room. A receiver lying half undressed in a draught is losing tolerance every minute you spend looking for the strap.

The four mistakes I see most

1. Treating warm-up as a countdown to the real thing rather than part of it.
2. Starting hard and slow instead of light and fast.
3. Working one spot, so you get a hot patch and a cold everything else.
4. Reaching for an implement at the first sign that the hand is not enough, when what is actually needed is four more minutes of hand.

None of this is complicated. It is just slower than people want it to be, and the discipline of doing it anyway is most of what separates a session people want to repeat from one they quietly do not.
