This chapter describes a life course approach for understanding later life sustainability, focusing on grip strength as a marker of physical sustainability, and explaining how a life course approach recognizes that muscle strength in later life reflects not only rate of loss in later life, but also the peak attained earlier in life. We present evidence that risk factors operating throughout the life course have an impact on physical sustainability in later life with particular consideration of the effects of body size, socioeconomic position, long-term conditions, physical activity, diet, and smoking. We have shown that low birth weight is associated with weaker grip strength across the life course and that there is considerable evidence for developmental influences on ageing skeletal muscle. Finally, a life course approach suggests opportunities for early intervention to promote later life physical sustainability; but optimal strategies and timings for intervention are yet to be identified.
