Okay kiddo, let me explain what exercise trends are!
You know how some people like to do different things for exercise, like jogging or riding their bike? Well, trends are like the most popular things that people are doing for exercise.
Sometimes, lots of people will start doing a certain type of exercise because they hear it's really good for them or it's fun. For example, a few years ago, a lot of people started doing yoga because they liked how it made them feel.
Nowadays, some popular exercise trends are things like high-intensity interval training (which is like doing short bursts of really intense exercise), and virtual fitness classes (which are classes you do online instead of in person).
But just because something is trendy doesn't mean it's the best thing for everyone. It's important to find an exercise routine that works for your body and your interests. As long as you're moving your body and staying healthy, that's what matters most!
