Exercise

Where to start

This section translates the evidence into a weekly framework. It is organised into three tiers — Start here, Build on it, and Optimise — that build on each other. Members who are currently doing nothing should begin with the first tier and stay there for a month or two before moving on. Members who already train should use the tiers to work out which of the five training areas they are neglecting.

One principle runs through all three tiers: consistency beats intensity. A member who trains for three hours a week every week for a year will be meaningfully fitter than one who trains for six hours a week for two months and then stops. Exercise is a slow-feedback system. The adaptations that matter — new mitochondria, new muscle, a stronger heart — take weeks and months to build, and they dissolve within weeks when training stops. Whatever pattern you build, build it to last.

A second principle: respect where you are now. The injuries and demoralisation that derail beginners almost always come from trying to do what a fit person does before the body is ready. Progressive overload — adding weight, time, or difficulty in small increments — is the organising principle. A week’s worth of modest training done reliably is worth more than a herculean weekend followed by five days of soreness and a fortnight off.

Start here

For members who are currently sedentary or close to it. Three things, done consistently, for at least a month before adding more. The goal is to build the habit of moving regularly before building the volume or intensity. Total weekly commitment: roughly 2-3 hours.

If this is where you are starting, stay here for at least four to six weeks before adding anything. The trap at this stage is enthusiasm — doing too much, too soon, and failing. The members who end up with sustainable routines are almost always the ones who did less than they thought they should, for longer than felt necessary, before progressing.

Build on it

For members who have been training consistently for a couple of months and are ready to add volume and variety. The goal at this tier is to cover all five training areas, even if not at full dose. Total weekly commitment: roughly 4-5 hours.

At this tier, most members will start to feel noticeably fitter. Daily tasks — stairs, shopping, playing with grandchildren — become easier. Blood markers begin to improve visibly if you have them measured. The body starts to feel like it is on the way back rather than in decline.

Optimise

For members who are already training consistently across multiple training areas and want to add the finer details — higher-intensity work, more precise Zone 2 targeting, structured progression. This tier most closely resembles the Sarah portrait in section 3. Total weekly commitment: roughly 6-8 hours.

At this tier, the training is not a supplement to your life — it is part of how your life works. The weekly rhythm holds steady across years. Minor injuries are managed without derailing the pattern. Progress becomes incremental: small, measurable gains in VO2 max, in weight lifted, in time to fatigue. This is what sustained training looks like over decades.

A few practical notes

On equipment

Very little of what matters requires expensive kit. For strength, a pair of adjustable dumbbells, a resistance band, and a pull-up bar (or a sturdy beam) cover most needs for the first year. For cardiovascular work, shoes and a route. A heart-rate monitor — either a chest strap or a decent watch — becomes genuinely useful at Tier 3 to keep Zone 2 honest. A gym membership is not necessary, though it can be helpful for access to barbells and machines once you progress to heavier strength work.

On time

Members commonly overestimate how much time they need. Tier 1 is 2-3 hours a week — less than a single binge of a streaming series. Tier 2 is 4-5 hours — the time most people spend on their phones in a single weekend. Tier 3 is 6-8 hours — still under an hour a day on average. The constraint is almost never time; it is priority.

On starting age

The research on starting exercise in midlife or later is encouraging. Adults who begin training between 50 and 65 see substantial improvements in cardiorespiratory fitness, muscle mass and functional capacity within 12 to 24 months. The decline that preceded the start is partly reversible, and the forward trajectory is sharply altered. It is never too late to start, and the benefit of starting now compared to starting in a year is substantial. The worst decision is to wait.

On injury

Most beginner injuries come from one of three things: doing too much, too soon; progressing too quickly; or using poor form on a movement the body is not ready for. All three are avoidable. The rule of thumb is that if a session leaves you so sore you cannot train again for five days, you did too much. Some soreness for a day or two is normal and expected. Persistent pain, particularly joint pain, is a signal to back off and reassess — not a badge of honour to push through.
