What you can do to stay in touch with your gold game will largely depend on where you live and what facilities you have access to. From a large mansion with gardens and gym to small studio condo there are things you can do on a regular basis to keep your game strong.
Practicing putting is probably the easiest activity you can do because this can even be done in a small condo. You just need a flat surface and something to aim for, of course you can putt on a carpet or hardwood floor and use a paper cup as a makeshift hole if necessary. To make it a bit more realistic get a custom-made hole to aim for, they're cheap and are usually low tech. To add to realism try adding a simulated grass mat, you can get them in a variety of sizes and some even end with an uphill section incorporating a built-in hole to drop successful puts into.
If you are limited to a small room there will be limits to what you can physically do. There are some swing training aids that are compact enough for a small room that can simulate swings for practice. For those with a garden practicing your swing will be a lot easier, you can use your real clubs for starters. For added realism why not try incorporating a catch net then you can strike real balls. Alternatively, there are other swing aids that incorporate a plastic ball attached to a solid base that you can strike with real clubs too.
