The Ten Ten

A gym and a personal trainer may be the gold standard, if you can keep them up. For the great majority who cannot — the person writing this included — here is the twenty-minute version that does most of the work.

For busy people, or to tune in when on the move, a Google NotebookLM audio podcast is available as a story beneath.

The gold standard, and the rest of us

If you have the time, the money and the inclination, the best exercise prescription available is a gym, a personal trainer and three or four sessions a week, kept up for years. Supervised training produces more strength than the same programme done alone, largely because a trainer makes you lift heavier than you would choose. Some of my patients manage this, often in retirement, and I congratulate them.

They are few — among the patients I see, fewer than one in twenty, by my own estimate. Everyone else has a job, children, parents, a commute and a finite supply of willpower. I am one of them. I do not enjoy gyms, and for years I did nothing because, like most people, I assumed exercise meant a membership and hours every week. It does not.

Built for the lives we actually lead

Modern life has taken the movement out of the day. In the early 1960s almost half of American jobs required at least moderate physical activity; now fewer than one in five do. The average US worker spends close to half the working day sitting, and UK office workers wearing activity monitors were sedentary for around 70% of their working hours. Add the lorry drivers, van drivers and delivery fleets, and the hunter-gatherer day of walking, carrying and climbing has become a day spent between a car seat, a desk and a sofa.

Our children have followed us. Only about half of children in England manage the recommended hour of activity a day, and in the United States only about one high school student in four. The bike rides and the running about have given way to screens: UK children aged 8 to 14 spend nearly three hours a day online before television and games consoles are counted, and American teenagers average more than eight hours a day of entertainment screen time.

What people in this position need is not a hill they will never climb. Large studies are consistent that something is far better than nothing, and that the biggest gain comes from the first step up from doing none.

A go-to that moves the needle

The benefit of exercise is not spread evenly across the hours. For strength training, the gains in strength, function and metabolic health rise steeply at low doses and then flatten; extra hours mostly add muscle size, which health needs least. The parts that do most of the work are three: muscle loaded progressively, heart and lungs pushed hard for short periods, and a daily base of ordinary walking.

My working aim is to capture something like 80% of what a committed gym-goer gets, in a fraction of the time. That figure is my target, not a finding from any trial — but the shape of the curve makes it reasonable, and it turns a prescription almost nobody follows into one almost anybody can.

The Ten Ten

On top of a daily base of 7,000–10,000 steps — a walking commute, the stairs, a brisk walk, a walk-and-talk meeting — ten minutes of progressive strength training with free weights at home, five days a week. Then ten minutes of hard, low-impact intervals — bike, cross-trainer, ski machine or fast uphill walking — especially on any day you fall short of your steps. Fixed time; rising load. Aim for every day and count five as a good week.

The first ten: strength

A pair of adjustable dumbbells, a clear patch of floor, ten minutes. Cover the big movements — a squat, a push, a pull, a hinge — and work each set until only one to three good repetitions remain in you. Muscle worked this way gets better at taking up glucose, and short, frequent sessions build strength as well as longer ones when the weekly total is similar.

At home, you are your own trainer. Keep the clock fixed at ten minutes and let the weight rise: when fifteen repetitions feel comfortable, move to the heavier pair. Ten minutes that never gets harder soon becomes ten minutes of maintenance. You are not trying to get big; strength and protection against frailty arrive long before visible size.

After the menopause more is needed: muscle responds less readily and bone needs genuinely heavy loading. The answer is not more minutes but heavier ones, and a period of supervised training is worth its cost here. Ask about bone assessment where your risk warrants it.

The second ten: hard, but low impact

Walking does not maintain muscle, and strength work alone does little for cardiorespiratory fitness — which predicts survival as strongly as smoking or diabetes. The format I favour is two or three efforts of two minutes, hard, each followed by two minutes easy. Hard means you cannot hold a conversation during the effort and can during the recovery.

My strong preference is for low impact: an exercise bike, a cross-trainer, a cross-country ski machine on a gradient, or fast walking up a steep hill or an inclined treadmill. All reach the same breathless effort as running without the pounding. Fast uphill walking is the best of both worlds, because it still loads bone. A bike or cross-trainer does not, so bone has to come from the strength ten and your walking.

Why especially on days short of steps? For the driver or desk worker, ten hard minutes buys back much of the fitness and visceral-fat benefit of a more active day. It does not buy back the sitting itself, so still stand up, walk the call and take the stairs.

If you can keep up the gym and the trainer, do. For everyone else, the best programme is the one you will still be doing in ten years.

Every day, and without injury

"Three times a week" asks for a decision every morning, and that decision is where habits leak. A daily default removes it. Missing a day does not undo a habit; missed days are your recovery, and five in a week is a good week.

In middle age the commonest reason people stop is not motivation but injury, and two weeks off costs measurable muscle. That is why I steer people away from running as their hard ten. People new to running are injured far more often than established runners, and the new runner is exactly who this is for. Recreational running over many years is not, on the whole, bad for joints — but for a deconditioned body starting from scratch it carries the highest chance of an injury that stops everything. Build gradually, avoid sudden jumps in load and repeated overhead pressing, and treat a persistent niggle as a reason to hold the load steady.

What it moves, and how to tell

Of the four pillars, the Ten Ten acts most on visceral fat, which your waist-to-height ratio tracks, and on the glucose and insulin that tend to follow it. Blood pressure improves with activity, but often not enough on its own when clearly raised; LDL and ApoB barely shift with exercise. If one of those was your weak column, keep going, but take that number to your doctor.

Ignore the scales, and be wary of the muscle estimates on bathroom scales, which can fall during weight loss even as you get stronger. Watch your waist with a tape, your strength with the weights you lift and a 30-second sit-to-stand each month, and your hill — the high street or station stairs you will know without a watch have become easier.

If you have known or suspected heart disease, an exertional rhythm problem, uncontrolled blood pressure, significant valve disease or a recent heart attack, speak to your doctor before the hard efforts; a gentler format suits almost everyone.

Then, in twelve weeks, run your four pillars again. You measure; if a column is not where it should be, you take the numbers to your doctor.
