Minimalist Home Gym Essentials for Apartment Living (UK/US)

Hey team,

I'm in an apartment, and space is a huge premium. I'm trying to figure out the absolute minimalist setup for a home gym that's still effective for strength and general fitness. I'm talking about things that can be easily stored away or take up very little floor space.

I've got a yoga mat and some light dumbbells, but I feel like I could be doing more. What are the top 3-5 items you'd recommend if you had almost no space? Things like resistance bands are a given, but what else? A kettlebell? An ab wheel? Maybe something for dips?

I'm based in London, so access to certain brands might differ slightly from the US, but general product types are universal. The goal is to get a solid workout without turning my living room into a permanent gym. Any savvy space-saving tips would be much appreciated!
