Variety in Exercise Linked to Longer Life, Study Finds Researchers following over 30 years the habits of 111,000 adults discovered that those who diversify their physical activity-mixing walking, jogging, cycling, weight training, gardening and stairs-have a 19% lower risk of premature death compared with those who stick to one type of exercise. The study, published in BMJ Medicine, shows that the benefit comes from varied movement rather than the total hours spent exercising. Harvard T.H. Chan School of Public Health post‑doctoral researcher Han Han explained that combining different forms of activity trains the body’s systems, improves mental health, reduces overuse injuries and keeps motivation high. Nutritionist and trainer Albert Matheny added that even simple activities such as gardening or playing with children add valuable variety. Experts recommend maintaining a core activity while periodically adding new ones such as swimming, cycling or strength‑training variations. The findings suggest that an active, varied lifestyle can help people live longer and healthier lives.
