On the surface, it seems like long exercises are by far the best option. After all, longer exercises mean burning more calories, which means losing more weight. However, as many fitness experts have begun to preach over the years, it isn’t anywhere near as simple as that. The reality is that there is a lot of evidence that doing exercise in short bursts can potentially be better for you than doing a super long workout. However, doing exercise in short bursts isn’t for everyone. In this article, you are going to see the pros and cons of each approach.

The Pros and Cons of Each Method:
If you have been around fitness experts or been to a gym, then you may have heard of HIIT, which is short for “high-intensity interval exercise.” The idea behind this approach to fitness is that you do extremely intense exercises in short bursts before switching over to very light exercise for a longer period of time. And by “short bursts” we really do mean short. For example, in one HIIT routine, a person will do suicides for as little as 30 to 45-seconds. Then for 5-minutes they will jog and then do another set of suicides. They keep repeating this routine for around 30 to 45-minutes.

This may not sound effective, but short, intense bursts of exercise have been shown to be more effective at burning calories and burning fat than long exercise sessions. The science behind it isn’t 100% clear, but the general idea is that short bursts of exercise jumpstart your heart rate. A high heart rate is what causes your body to start burning lots of calories.

The downside here is that short bursts of exercise only work with really intense exercises. Things like sprints, suicides, and other very intense exercises are necessary. Not everyone is capable of doing these sorts of high-intensity exercises safely. Older people and people with muscle or joint issues can’t do most high-intensity exercises. Likewise, people who are either overweight or out of shape probably shouldn’t put their body under the sort of strain necessary to do HIIT or short burst workouts.

So, if you happen to fall into one of the above categories, then you should start out with long, slow workouts that get your body ready and into shape. Then, you can switch over to calorie burning and fat burning short workouts.
