Specificity
The idea that the body adapts specifically to the kind of training it is given — you tend to get good at what you actually practise.
Overview
Specificity is the principle that the body's adaptations are specific to the demands placed on it. Train a particular quality, movement or energy system and that is largely what tends to improve; the body responds to the exact stress it meets rather than to effort in general. It is often summarised as the SAID idea — specific adaptation to imposed demand.
In practice this means training that resembles the goal — in its movements, speeds, intensities and skills — tends to carry over to that goal best. Specificity works alongside overload: overload says training must be challenging, specificity says it must also be relevant. It is a general model, and how closely to match any one person's training to their goal is best guided by a qualified coach or professional.
The science
- The body adapts specifically to the type of demand placed on it.
- Often summarised as SAID — specific adaptation to imposed demand.
- Training that mirrors the goal's movements, speed and energy system tends to transfer best.
- Broad, general training builds a base; more specific training sharpens a particular quality.
- It works hand in hand with overload — training should be both challenging and relevant.
Why it matters
- It explains why a swimmer trains largely by swimming and a runner largely by running.
- It guides how closely a session should resemble the movements and demands of a sport.
- It connects to the coaching idea of transfer — how practice carries over to performance.
Educational only
Where it shows up
Sports where this concept is especially visible — each with a clear guide.
Running
The most accessible endurance sport — no venue, just shoes and the open road or trail.
Swimming
A full-body, low-impact endurance sport suitable for almost every age and ability.
Cycling
A low-impact endurance sport that doubles as transport, exercise and adventure.
Frequently asked questions
What is specificity in training?
It is the principle that the body adapts specifically to the demands it is given, so training tends to improve the qualities, movements and energy systems it actually uses. It is often summarised as SAID — specific adaptation to imposed demand — and how specific to make any person's training is best guided by a qualified coach.

Coaching concepts
- Transfer of TrainingWhether practice carries over to real performance — and why game-like, varied practice tends to transfer better than isolated, repetitive drills.
- Skill acquisitionHow a movement or sports skill is learned — progressing from conscious, effortful control to smooth, largely automatic execution through practice and feedback.
- Deliberate PracticeFocused, effortful practice that targets a specific weakness with full attention and immediate feedback — not just repeating what you already do well.
- ProgressionBuilding skill and training load in gradual, manageable steps so each stage prepares the next, moving from simple to complex and easy to hard.
Training methods
- Strength TrainingStrength training uses resistance — bodyweight, bands or weights — to challenge your muscles so they gradually adapt and get stronger over time.
- Endurance Base TrainingEndurance base training is an extended phase of mostly easy, steady aerobic work that lays the aerobic foundation the rest of a training plan builds on.
- Progressive OverloadProgressive overload is the principle of gradually increasing the demand you place on your body so it keeps adapting and improving over time.
- Tempo TrainingTempo training holds a firm, controlled 'comfortably hard' pace for a sustained stretch, teaching the body to sustain effort without tipping into a sprint.
- Hypertrophy TrainingHypertrophy training is resistance work structured to encourage muscle growth, typically using moderate repetitions and a steady, controlled tempo.
Movement patterns
- GaitThe cyclic, alternating single-leg pattern of walking and running that carries the body across the ground — the base of most field and endurance sport.
- HopA single-leg spring that takes off from and lands on the same leg, using the stretch-shortening cycle to project the body vertically or horizontally.
- PullDrawing a load or your own body toward the torso — horizontal rows and vertical pull-ups — building the lats, mid-back and biceps and balancing the push.
- RotationRotating the trunk to generate and transfer power through the body's kinetic chain, plus anti-rotation — resisting unwanted twist to keep the trunk stable.
Recovery
- Active recoveryActive recovery means very easy, gentle movement on lighter days to keep the body moving without adding hard training stress.
- SleepRegular, good-quality sleep is the foundation of everyday recovery for anyone who trains or plays sport.
- Rest daysRest days are planned days off from training that give the body and mind time to recover between harder sessions.
- Listening to your bodyListening to your body means paying attention to everyday signs like energy, sleep and soreness to guide how much you do.
- Cool-downA cool-down is a few minutes of easy movement at the end of a session to let the body settle back towards rest.
Practice & sessions
- Mobility sessionA session built around moving well through a range of motion — gentle, controlled work to help the body move freely.
- Recovery sessionA deliberately easy session — gentle movement to help the body feel better and adapt, rather than to push hard.
- Coached sessionA session led by a coach, who sets the focus, gives feedback and shapes the practice around what you need.
- Technical sessionA session built around technique — grooving and refining the mechanics of how a movement or shot is executed.
- Conditioning sessionA session built around physical conditioning — developing the fitness qualities a sport draws on, rather than its skills or tactics.
