Starting to train again after 40, without hurting yourself

You used to train. Maybe it was football on Tuesdays, maybe a gym card you used properly for two years. Then came the job, the kids, the commute, and one day you noticed it had been five years.

Now you want to start again. Good. This is the article about not ruining it in the first fortnight.

The classic mistake

Your memory of what you could do is from ten years ago. Your muscles, tendons and joints are not. Strength tends to come back first; the tissue itself takes longer. In one small study of eight people, strength was up by about 30% after two months of training, while the muscle had not yet grown and the tendon had not yet adapted. And tendon tissue renews itself very slowly. So it is easy to feel strong in week two, add weight, and have a tendon or your lower back pay for the gap.

The fix is boring and it works: start with less than you think you can do, and stay there longer than feels necessary.

What the guidelines actually ask for

The World Health Organization’s 2020 guidelines for adults say 150 to 300 minutes of moderate activity a week — brisk walking counts — plus muscle-strengthening on at least two days. That is the target, not the starting line. If you are at zero today, getting to half of it is already a real change.

Your first 12 weeks

Three phases, each four weeks. Move on only when the current one feels easy.

Weeks 1–4: learn the movements. Two strength sessions a week, 30 to 40 minutes, plus walking on most days. Start with five movements: a squat to a box or bench, a hip hinge (picking a weight up from the floor with a flat back), a push (press-up against a wall, then a bench), a pull (a row with a band or cable) and a carry (walk with a weight in each hand). Do two sets of eight to ten, and finish each one feeling you could have done three more.

Weeks 5–8: add load. Same two sessions. Now add a little weight or one more set when every rep of the last session was clean. Add a third short session only if you are recovering well.

Weeks 9–12: build the habit. Two or three sessions, one of them a bit harder. By now the routine should be part of your week, like a recurring meeting you actually want to attend.

Three rules to help you avoid injury

1. Stop a rep before form breaks. If your back rounds or your knee collapses inward, the set is over. Ego costs more than a lighter weight.
2. Soreness is fine, sharp pain is not. Stiff two days later is normal. A sharp or worsening pain in a joint or tendon, or pain that wakes you at night, means stop and get it looked at.
3. Sleep and food are part of the plan. You adapt while you recover, not while you lift. A week of five hours’ sleep is a week to train lighter, not harder.

When to see your doctor first

If you have not exercised for years and you have a heart condition, high blood pressure, diabetes, joint problems, or you are simply unsure, talk to your doctor before you start. It is a short conversation, and well worth having.

Do you need a coach?

You can do all of this alone. A coach is useful for three things: checking your technique while it is still easy to fix, writing the progression so you don’t have to guess, and noticing the week you need to back off before your body tells you. If that sounds useful, book an intake call and we will build a start that fits your week and your history.
