power rack

I like your booty, but I’m not gay

Only cardio machine you need is a rower - it’s full body and is different from all other cardio which is simply an augmentation on something you probably already have access to already (bike, stairs, the ground) - most don’t have a rowboat/canoe. Also a fantastic workout and my personal go-to. But you can just walk and get all the cardio you need with less wear of your joints/free.

For strength exercise, you can use a combination of bodyweight, bands, kettlebells, adjustable dumbbells, rings and a weighted vest to get massively strong. I’d recommend an adjustable bench and a strong cross bar to hang things off to do rings and pull-ups. Rubber matting also makes things a bit nicer. You can build a home gym in a couple of meters of space if that’s all you have. I say this even though I have a vast array of gym toys (rack, barbells, FT, plyo, leg sled, leg extension/curl, rings, dip bars, bike, rower, treadmill, pool, kettlebells, dumbbells, vest etc) but I started off small with just rings and kettlebells.

Get the cushioning matting and use it as a general exercise area.

Get free weights, medicine balls, etc.

Do squats, press ups, all sorts of body exercises, augment them with weights.

If any machine… mount a chin up bar to a wall or get a free standing one.

Whatever you are going to use regularly and not get bored with. Consistency is key.

If you’re getting free weights, I’d get an adjustable bench as well. If you already have a bike, you can get a bike trainer to ride inside when weather isn’t cooperating. I’d avoid a treadmill since as you mentioned, the outside is accessible, and if you’re not in a climate with snow and ice, a little rain sometimes feels good during a run.

But like others mentioned, dumbbells and a kettlebell will be all you need to do a lot of strength exercises. An adjustable bench allows you to expand on that. You can get dumbbells that use plates, so you dont need a full set, just the bars and plates. In the future you could get other bars for different strength training if you feel the need and you can just use existing plates.

Otherwise as someone else mentioned, you can do a lot with just bodyweight traing too. A good mat will go a long ways for that. You can supplement that with resistance bands that take up minimal space.

If you’re set on a machine i think a rowing machine.

Does arms legs core and cardio.

I’m torn between rower (as lots of people here have said) and one of those pull up station racks that also has dip bars. I love rowers for the efficiency of movement and you get lots of big muscle groups at once but the first thing that got me consistently working out was body weight exercises in my local park. I started with bands on a pull up bar and worked my way up to different pull up variations.

Bench + weights. Cardio is easy without a machine, weightlifting is not. If you’re not into weightlifting, then yeah, small treadmills/walking pads are great.

Weights and a bench like many have said, and what a lot of people don’t realize is that lifting (even low weights) can be very cardio intensive.

Pullup bar and gymnastic rings to hang in the pullup bar. You are set for life with bodyweight exersizes.

Whatever is most fun for you, I like stairsteppers or an exercise bike that I can do something while riding to distract myself, which makes me ride longer.

I bought an exercise bike but I made the mistake of buying one that is like riding a road bike so it’s super uncomfortable. If I did it again I’d buy the recumbent one where you are sitting back while pedaling. Much more comfortable and therefore much more likely to be used.

Rower is my choice

Kettlebell, adjustable dumbbells. Still saves you space.
