If you're limited with budget, you need info products. Maybe access to a workout plan, or a community. Or maybe there's a gym or spa in Scotland that you can partner with to offer a limited amount of day passes for the first 10 order etc. (They get foot traffic, you get eyeballs on your brand.) Whatever it is they have to be somewhat appealing.
Think of it as coming up with a lead magnet. If you want to brainstorm ideas drop me a dm, I love coming up with offers.
