Warming Up Properly

What a warm-up is physiologically doing, why five sun salutations is not always it, and a ten-minute version that fits any practice.

What warming up actually does

Raises tissue temperature. Warm muscle and connective tissue deform more readily under load. This is the main effect and it is real.

Increases blood flow to working muscle. More delivery, more waste removal, better performance.

Reduces tissue viscosity. Muscle and fascia behave a little like a viscous fluid — they resist rapid deformation less when warm.

Wakes up the nervous system. Reaction time and co-ordination improve after a few minutes of movement. A significant part of what a warm-up does is neurological rather than thermal.

Lubricates joints. Movement stimulates synovial fluid production. This is why the first few repetitions of any joint movement feel stiffer than the tenth.

Rehearses the patterns. A warm-up that includes the movements you are about to do primes those specific patterns.

Why "five sun salutations" is not always the answer

It is a reasonable general warm-up, and it has two limits.

It does not visit all four spinal directions. Sun salutations are flexion and extension. There is no rotation and no lateral bend in the whole sequence. If your practice includes twists or side bends — and it does — those directions arrive cold.

It is not specific. A warm-up should prepare what you are about to do. Five sun salutations before an hour of hip work warms you generally and prepares the hips barely at all.

And a third: on a cold morning, in a cold room, five sun salutations may not actually make you warm. Check rather than assume.

The structure

Three phases, ten minutes.

Phase one: joint mobility — 2 minutes

Small, unloaded movements through range. Not stretching — moving.

• Ankle circles, both directions.
• Wrist circles, flexion and extension.
• Shoulder rolls, then arm circles.
• Neck: slow turns, then side bends. Small range.
• Hips: standing, knee circles.

Why first: it stimulates synovial fluid and it costs almost nothing. Particularly worth it in the morning and in the cold.

Phase two: the spine, all four directions — 3 minutes

This is the part most warm-ups omit and it is the most important.

• Flexion and extension: cat-cow, ten rounds, slowly, one movement per breath.
• Rotation: thread the needle, five each side. Or a gentle seated twist.
• Lateral bend: standing or seated side bends, five each side. Or a puppy pose with the hips shifted to one side.

Every direction the spine can go, visited gently, before anything asks it to go there under load.

Phase three: raise the temperature — 5 minutes

Now get warm.

• Three to five sun salutations, stepping rather than jumping, at a moderate pace.
• Or: Downward Dog to low lunge to Downward Dog, repeatedly, both sides.
• Or: a set of standing poses held for three breaths each, moving briskly between them.
• Or: on a low-energy day, five minutes of slow standing poses.

The test: you should be breathing harder and feel warm. If you are not, keep going. Do not proceed to the main work on the assumption that you have warmed up because you did the routine.

Adding specificity

If the session has a focus, add two minutes of gentle preparation for that specific thing at the end of the warm-up.

• Hips: a few slow low lunges and a gentle supine figure-four.
• Backbends: two minutes over a rolled blanket, and five gentle cobras.
• Shoulders: strap work overhead, and puppy pose.
• Hamstrings: supine strap work at low intensity, one minute a side.
• Inversions or arm balances: wrist warm-up, thoroughly, plus plank holds.

Mild versions of what you are about to do hard.

When to warm up longer

• Cold rooms. Double it. Twenty minutes rather than ten.
• Mornings. Add five minutes; the body is at its stiffest and coolest.
• Over forty-five, roughly. Tissue takes longer to warm and is less tolerant of load when cold.
• After illness or a break. Longer and gentler.
• Before anything at end range. Deep backbends, splits, deep hip work.

When you can warm up less

• A hot room does some of it for you, though the neurological part still needs movement.
• After other activity — you have walked, cycled, or trained already.
• Late afternoon, when core temperature is at its daily peak.
• A restorative practice. Nothing is being loaded, so there is nothing to warm up for. Get straight in.

What a warm-up is not

It is not stretching. Long static holds before strength work reduce force production temporarily, and stretching cold tissue is the thing you are trying to avoid. Move first; stretch later, or at the end.

It is not the practice. A warm-up that leaves you tired has cost you the session. Moderate pace, moderate range.

It is not optional because you are short of time. If you have twenty minutes, warm up for eight and do twelve minutes of work. Not two minutes of warm-up and eighteen of work — that is the arrangement that produces injuries in people who are short of time.
