Walking isn’t enough anymore: what truly helps you stay strong past 70
Exercise keeps coming up when we talk about living longer and feeling better. Walking is often recommended for cardiovascular health and mood, but recent findings suggest other factors should be considered. Researchers now advise a more nuanced approach to fitness as we age and question familiar ideas such as the “10,000 steps a day” target.
What walking can, and can’t, do
Walking is beneficial for heart health and mood; research indicates these benefits are well established. But as we get older, especially past 70, walking on its own may not be enough to maintain full health. Dr Alfonso Jiménez, an expert in motor and health sciences at Rey Juan Carlos University and director of GOfit LAB, explains that the body undergoes fundamental changes with age. After 70 years, he says, the body enters a state he calls “global fragility”, which affects balance and strength. This stage reflects falling bone density, stiffer joints and loss of muscle mass.
Dr Jiménez describes bones, joints and muscles as our “armour”. They are what let us move and stay independent. Around 70, that armour can start to weaken unless it receives the right kind of stimulation, so adding other types of exercise becomes more important.
Why strength training matters
It is worth rethinking routines after 50 and 70 years. Walking often does not trigger the physiological “dialogue with cells” needed to maintain bone density and stimulate muscle renewal. That is where strength training comes in: it is a key tool for maintaining independence and reducing injury risk as we age.
Combining strength work with exercises that introduce controlled instability helps improve balance and reduce the risk of falling. Dr Jiménez recommends allowing at least 48 hours of recovery between sessions so the body can adapt. Muscles and the nervous system respond particularly well to external loads and dynamic movements, which in turn help people remain active into their seventies and beyond.
As Dr Jiménez puts it, “Only a specific mechanical load can ‘dialogue’ with the cells, pushing the bones to strengthen and the muscles to regenerate.” A practical example is stepping on and off a step while tossing a ball; this works on strength, coordination and balance all at once.
Getting started safely
Starting a new fitness plan after 50 can feel intimidating, but working with qualified professionals can lead to quick and safe improvements. Dr Jiménez stresses beginning with bodyweight exercises, focusing on proper technique and coordination rather than heavy weights at first. Safety is the foundation of any programme, allowing steady but meaningful progress.
Muscle decline is not inevitable. Research on centenarians shows the body can still improve past 100. Muscle tissue remains responsive to the right mechanical stimulus at any age, so the benefits of strength work can appear even in later decades.
Strength, balance and living well
Maintaining strength and balance goes beyond physical health. Staying active supports mental and emotional wellbeing through greater autonomy and social engagement. Dr Jiménez explains, “Preserving a minimum level of functionality not only improves physical health but has a direct effect on mental and emotional wellbeing.”
Exercise becomes a way of staying connected with life outside the home, not just a way to keep fit. Being involved in the world around you boosts self-worth and helps counter the loneliness sometimes linked with older age.
A fitness routine that mixes strength, balance and mental stimulation can improve both longevity and quality of life. With guidance from specialists such as Dr Jiménez, staying active at any age supports safety, independence and wellbeing.
