Should you start lifting weights?
Live MintBarbells; chalk; the clang of iron plates. Even Peloton, a purveyor of expensive exercise bikes to the aspirational classes, is picking up the dumbbells—it now has an app targeted at strength training, rather than the cardio workouts on which it built its brand. A study published in 2020 estimated that although around half of Western adults reported meeting the weekly guidelines for cardiovascular exercise such as jogging or cycling, only between 10% and 30%, depending on the country, claimed to meet the minimum for strength work. There’s no doubt cardio is good for you—it lowers blood pressure, cuts the risk of heart disease, strokes and some kinds of cancer, and may even help treat depression. The evidence is less robust than for cardio, but a review published in 2022 concluded that regular strength training seems to reduce the risk of heart diseases, diabetes and cancer.
