I found having to actually go to the gym was a huge hurdle for me so I bought a 200lb set of adjustable dumbbells and a foldable weight bench for at home. It’s nice because if I get lost in something and forget to work out until later I can still do something on the spot. If I had room I’d buy a full weight set but I’d need a house for that. If you don’t want to spend money or don’t have space there’s also a lot of bodyweight stuff you can do at home.
