Choosing the right intensity
Choosing the right intensity is about matching how hard a session feels to its purpose, so most training stays comfortable and sustainable.
Overview
Intensity is simply how hard a session feels. A common beginner trap is doing every session at roughly the same moderately hard effort, which can feel tiring without being especially effective. Varying intensity on purpose tends to work better.
A widely used idea is that most training should feel easy to comfortable — an effort at which you could hold a conversation — with only a smaller portion feeling genuinely hard. Easy sessions build a base and are easy to recover from, while the occasional harder session adds a different stimulus.
You do not need any gadgets to judge intensity. Simple self-checks work well: how hard your breathing is, whether you could still talk, and a rough mental rating from easy to maximal. These let you steer each session to the effort you intended.
How to do it
- 1Decide the purpose of the session before you start — easy, steady or hard
- 2For easy efforts, keep a pace at which you could comfortably hold a conversation
- 3Save harder efforts for a small number of sessions each week
- 4Use the talk test or a simple effort rating to check you are on target
- 5Adjust up or down during the session so the effort matches your intent
Key points
- Intensity just means how hard a session feels
- Aim for most sessions to feel easy to comfortable
- Keep genuinely hard efforts to a smaller share of your week
- Easy sessions build a base and are easy to recover from
- Simple self-checks like the talk test work fine — no gadgets needed
A note on training information
Where it’s used
Sports this relates to:
Running
The most accessible endurance sport — no venue, just shoes and the open road or trail.
Cycling

How to warm up
A short, gentle warm-up gradually raises your body temperature and prepares your muscles and joints for the activity ahead.
How to cool down
A cool-down is a few easy minutes at the end of a session that let your effort taper off gradually before you stop.
How to build a weekly routine
Building a weekly routine means loosely planning your training across the week so effort and rest are spread out in a way you can sustain.

Sports science
- Energy systemsHow the body supplies energy for movement — the different pathways that power everything from an explosive jump to a long, steady run.
- Aerobic and anaerobic energyThe difference between energy the body produces with oxygen and energy it produces without it — a core idea behind why different efforts feel and last so differently.
- Individual differencesThe idea that people respond to the same training differently — so what works well for one person may not suit another.
Coaching concepts
- 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.
- Session StructureHow a practice session is organised into phases — warm-up, main focus, game application and cool-down — so time is used well and learning sticks.
- Decision-Making PracticeTraining athletes to read cues and choose the right action under pressure — coupling perception to action, not just rehearsing physical technique in isolation.
Training methods
- High-Intensity Interval Training (HIIT)High-intensity interval training, or HIIT, packs short, hard efforts against brief recoveries into a compact session, making it a time-efficient way to train.
- Steady-State CardioSteady-state cardio means holding one comfortable, continuous pace for the whole session, building an aerobic base without the peaks of interval work.
- Circuit TrainingCircuit training moves you through a series of stations back to back with little rest, blending strength and cardio into one time-efficient session.
- FartlekFartlek — Swedish for 'speed play' — mixes faster and easier efforts freely and by feel within one continuous session, blending steady and interval work.
- Mobility TrainingMobility training works on moving your joints actively through their full range, combining control and flexibility so movement feels free and easy.
Lifestyle
- At the gymHow to make the most of a gym — strength machines, free weights, classes and cardio kit under one roof.
- 30 minutesA half-hour is enough for a proper, well-rounded session across many sports and workouts.
- 1 hourA full hour opens up almost any sport, from a proper game to a longer ride, run or gym session.
- EveningUsing the evening to be active after work, whether to unwind or fit in a proper session.
- At homeMovement you can do in your living room — from bodyweight strength to yoga — with little or no equipment.
