High-Intensity Interval Training (HIIT) has gained popularity as an efficient workout method, promising significant health benefits in less time compared to traditional exercise routines. For beginners, understanding the evidence supporting HIIT is crucial to making informed decisions about incorporating it into their fitness regimen. This article delves into the scientific backing of HIIT, its trends, implications for US readers, and relevant examples and data.
