What is a fart walk and why is it so good for ageing?

According to a 2019 study published in the *Mayo Clinic Proceedings*, interval walking training (IWT) significantly improves aerobic capacity and reduces the risk of lifestyle-related diseases in middle-aged and older adults. A 'fart walk' is a form of this scientifically-backed IWT, which is so good for ageing because it alternates bursts of brisk walking with periods of recovery to safely and effectively boost physical and mental well-being.
