    What's your existing drivetrain?

    Go to the Drivetrain forum. And when you ask, write out in detail what drivetrain components are installed on your bike. That will take less time than for each potential responder to go look up your bike's components.

    I owned that exact bike. You should have a 2x10 setup with a 11-36t cassette. I suggest an 11-42t cassette and a goat link. The Sunrace 11-42t and goat link can be found readily in good bike shops and online.

    Then when you grow some legs ditch the front derailleur and go a single ring.

    Or just keep the current set of legs and get a 28 ring in the front!

    Nope. It would be a higher gear. But 26/42 or 28/46 would be pretty comparable. Gear ratios are literally ratios, so if you're not changing wheel size, you can just do the division to compare different options.

    so 42/28=1.5
    and 36/22=1.64

    so 36/22 is an easier ratio

    Usually people divide the chainring teeth by the cog teeth. So a lower number corresponds to a lower gear.

    Well, you can calculate any way you like, 22/36 is still easier ratio then 28/42

    This is my advice...grow some legs and the gearing and ratios will come easy.
