I took a look at your domain and honestly, I think it needs a lot of work. At the very least, hire an editor to fix all the grammar errors that currently plague your site.
Next, the logo is far too small and doesn’t ooze authority in the slightest - this is a big issue when trying to build a fanbase. You only have two products atm, but even for them, there isn’t enough info to persuade anyone to press the “buy” button. Consider publishing attention-gripping descriptions for those items, together with some more high-res photos. Later on, expand those sections with articles dedicated to home workout equipment and user testimonials.
Other than that, since you’re venturing into a busy niche here, I’d recommend utilizing every possible form of digital marketing - on-page SEO, newsletters, paid ads, collaborating with Insta influencers, etc.
