HIIT or SIT: Which of these popular fitness trends is best suited for you?

If one was to choose the most popular workout, then High Intensity Interval Training would probably take home the award. SIT significantly outperformed HIIT in Body Fat Percentage reduction while requiring 60.84% less time spent exercising than HIIT,” it states. “HIIT does not require maximal training intensities, in fact, most studies show very welcome improvements in fitness, and reductions in body fat can be achieved with training intensities around 80-85% of maximal heart rate, which for many is very achievable on an ongoing basis,” says an article titled HIIT vs SIT on functionaltraininginstitute.com. Another article, titled HIIT vs SIT: Will Either Of Them Make You A Better Triathlete says that VO2 max should not be a big worry for most fitness enthusiasts: “SIT’s claim to fame seems to arise from its ability to improve VO2 max to about the same degree as longer bout HIIT. The problem is that higher VO2 max does not necessarily correlate with improved performance, which is the goal of most athletes.” So while HIIT might be sliding down the pecking order of popular fitness trends, it is still a tried and tested method, as long as you don’t get too comfortable in the workouts.
