How to return to exercise after a long break

There are two versions of returning to exercise. In the first, you start where you left off, hurt yourself or exhaust yourself within a fortnight, and stop again. In the second, you start embarrassingly small and are still going in three months. Almost everyone attempts the first one.

The reason is that your memory of your capacity doesn't decay at the same rate as your capacity. You remember the distance you used to run or the weight you used to lift, and that number becomes the target on day one.

Set the starting point deliberately low

A workable rule: begin at roughly half of whatever you think you could manage today, and hold there for two or three weeks even when it feels easy. If you used to run five kilometres, start with a walk-run of two. If you lifted a certain weight, start well beneath it and rebuild the movement first.

The reason isn't caution for its own sake. Your heart and lungs adapt relatively quickly; tendons, ligaments and joints take longer, and they are what tends to fail when the training load jumps. Many overuse injuries in returning exercisers come from doing too much too soon rather than from doing anything inherently wrong.

What to expect in the first month

The first two or three sessions will feel worse than you expect, both physically and in terms of how it compares with what you remember. That is the flattest part of the curve, and it passes reasonably quickly — previously trained bodies tend to regain fitness faster than untrained ones build it.

Expect some muscle soreness a day or two afterwards, particularly early on. Expect your sleep and appetite to shift. Expect a session where you feel unaccountably heavy. None of it means the return has failed.

Choose a frequency you can defend on a bad week

The temptation is to design a schedule for the version of your life where nothing goes wrong. Design instead for an ordinary week with a late meeting, a poor night's sleep and something unexpected.

For most people that means two or three sessions of twenty to forty minutes. Fix them to specific days and times and treat them like appointments. Attaching a session to something that already happens — before the school run, straight after work, the same two mornings each week — is more durable than intending to fit it in.

Recovery, when everything is already tired

Coming back to exercise is an extra demand on a life that presumably already has demands in it. Leave a day between harder sessions at first. Prioritise sleep over squeezing in an extra session — training on four hours' sleep produces fatigue rather than fitness.

Walking on non-training days is genuinely useful and doesn't compete for recovery. It also keeps the habit alive on the days you aren't doing anything formal.

Breaking the all-or-nothing pattern

The cycle is familiar: an intense start, a missed week, the conclusion that you've fallen off, and a stop that lasts months. The missed week is not the problem. The interpretation is.

Two practical defences. First, define a minimum version of a session — ten minutes, one set of each movement, a short walk — that counts as done. It keeps the habit intact on days when the full session isn't going to happen. Second, decide in advance that the response to a missed week is simply the next session, at the same level, with nothing added to make up for it.

Motivation is unreliable and always has been. What holds a return together is a schedule small enough to survive an ordinary bad week.

Measuring progress without a scale

Weight is a poor measure of whether training is working, especially early on. More informative markers: the same walk feeling easier, recovering faster afterwards, adding a repetition, sleeping better, stairs stopping being noticeable.

Keep a short record. Three months in, the notes are the only reliable evidence of how far you've come, because the improvements are gradual enough to be invisible from inside.

When to get individual advice first

Speak to a healthcare professional before starting if you are returning after illness, surgery, injury or pregnancy, if you have a long-term condition, if you have chest pain, breathlessness disproportionate to the effort, dizziness or fainting, or if you have been told to be cautious about exercise. A physiotherapist is the right person for a specific injury, and a qualified coach for technique.

General information can describe how returning usually works. Whether a particular plan is safe for your body, at this point, is an individual question — and the answer is worth the appointment.
