HIIT
Short bursts of effort, big results
Overview
HIIT — high-intensity interval training — alternates short bursts of demanding effort with brief periods of rest or easier movement. A session might combine bodyweight exercises, cardio movements and simple conditioning into a fast, time-efficient workout.
The interval structure lets you get a challenging workout in a relatively short time, and the exercises can be swapped or scaled to suit different fitness levels. Because the effort is genuinely hard, a good warm-up and sensible progression matter, especially when starting out.
Why hiit is good for your health
- Builds cardiovascular fitness through repeated hard efforts
- Combines conditioning and strength in a time-efficient session
- Develops stamina, power and full-body movement
- Intervals can be scaled to match a wide range of fitness levels
The social side
- Group classes bring shared energy and motivation
- Working through intervals together builds camaraderie
- Scalable formats let mixed-ability groups train side by side
How to start as a beginner
- 1Warm up thoroughly before any high-intensity work
- 2Start with longer rest periods and lower-impact movements
- 3Focus on good form, and stop an interval early if technique slips
- 4Join a coached beginner class to learn safe intervals and progression

Glossary
- Interval trainingInterval training alternates short bursts of harder effort with periods of easier recovery.
- Rating of Perceived ExertionRPE is a subjective scale on which athletes rate how hard an effort feels, used to gauge and prescribe training intensity.
- AnaerobicRelating to energy production without oxygen, powering short, high-intensity efforts lasting from a few seconds up to about two minutes.
- Threshold TrainingThreshold training is sustained work at or near the effort where lactate begins to accumulate faster than the body can clear it, done to raise that ceiling.
- Putting greenThe area of very short, smooth grass surrounding the hole on a golf hole.

Practice & sessions
- 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.
- Tactical sessionA session built around tactics — how you use space, position and patterns of play, rather than the mechanics of a shot.
Sports science
- Managing fatigue and loadThe educational idea of balancing how much training you do against how well you recover, so effort turns into progress rather than into excess fatigue.
- SupercompensationA widely taught model of how the body, after a bout of training and enough recovery, can rebuild to a slightly higher level than before.
- Recovery and adaptationThe idea that the body adapts during recovery, not during the effort itself — which is why rest is treated as part of training rather than a break from it.
- Reaction timeThe short delay between a signal and the start of the movement made in response to it.
- SpecificityThe idea that the body adapts specifically to the kind of training it is given — you tend to get good at what you actually practise.
Experience levels
- AdvancedA high level of skill and fitness — progress becomes finer, more individual, and increasingly benefits from expert coaching.
- EliteThe highest level of performance — a full, individualised, professionally supported pursuit far beyond what a general guide can direct.
- CompetitiveTraining and playing to compete — structured, goal-directed preparation built around events, with coaching and recovery central.
Healthy living
- Recovery walkingEasy, relaxed walking used as a way to recover — a low-effort way to keep moving on off days and after harder sessions.
- Recovery MealsThe general idea of eating after activity to help your body refuel and recover — simple, not scientific.
- Active BreaksShort bursts of movement woven through the working or study day to break up long stretches of sitting.
- Recovery SleepThe role rest plays in helping your body recover, adapt and feel ready after training and active days.
- Taking the StairsChoosing stairs over the lift as a simple, no-cost way to add a little more effort to an ordinary day.
