The secret to easier exercise as an adult may start in childhood
A study on guinea fowl found that birds who carried weights in childhood required less energy to do so as adults. In contrast, birds who did not carry weights as young birds used more energy when carrying them later in life. Researchers are exploring potential human applications of this discovery.
Why it's good news: It suggests that developing healthy exercise habits early on could make physical activity easier and less exhausting over time.
