Need advice on home cardio equipment

Hello good people of the Scooby community

Just a little background on myself. I believe I joined 2,5 years ago and I've took up jogging about 2 years ago. Used to be 6 days a week when I was off work but now I do around 50min 2x a week which is not terrible I guess. I even made my girlfriend jog too but she has stopped since 3 months ago (too cold etc.) and now she's seeing the consequences - EVIDENT body mass gain and overall being a lazy bum more too often haha (and she's far from being chubby even at her worst).

Well long story short we decided to buy a cardio machine for home. Now this is where your expertise can come in guys I have no idea what I want, all I know is I would not prefer a treadmill (I'd rather go jogging outside then). Maybe an elliptical machine? I've often seen in MMA fighter videos they use that machine where it's like a bicycle for the legs and 2 poles for the hands to move too, would that work for a girl too? We want something we can both use and preferably with an adjustable speed/difficulty level + as safe as possible. When I actually think about it now, I realise how little I know about home cardio equipment.

Much appreciated in advance and sorry if there was a similar thread somewhere already, drop a link and I'm on it


*UPDATE*

So I browsed around a bit and I can see it mainly comes down to elliptical vs treadmill. Treadmills take up more space and are louder when operating, but you look pretty goofy on an elliptical haha Also, I'm very skeptical about how much of an effective workout is the elliptical. Let's say I want to do an intense 40-50min cardio, with a treadmill I just pick up the pace - simple, but can you ramp up the difficulty with and elliptical? This is my main concern, since I sometimes want to do cardio to really exhaust myself and I feel it will be hard to achieve that.

I'm starting to reaaaaally consider a stationary bike right now, it has to be something me and my girl could both use. Rowing sounds really cool but I doubt I could convince her What tips could you give for people who are choosing a stationary bike? We'll probably be looking into something mid-range, something not completely plastic and with at least the basic electronic features (which are? ).

Oh btw, how taxing is the bike on joints compared to jogging and using an elliptical machine? Somewhere in-between I'd assume?

Question regarding bikes:

1) What's the difference between "magnetic" and "electronic" bikes? (if that makes any sense)
2) Flywheel (I see it in most descriptions, it's measure in Kilograms) - what is it and is heavier=better always?
3) What are the main factors, besides seat and overall comfortability, are really important when choosing a stationary bike?

Thanks guys

try out P90 X, zumba  or do something like boxing or any martial arts, dance which is lot better than doing a cardio equipment for long time

it is fun , you learn a new thing and cardio

My advice with stationary bike is be careful buying a folding one. I bought one a couple years ago and it was not to sturdy and when I tried to go fast mentally i couldn't because i was always afraid of tipping over. so make sure what ever you buy is sturdy.

also how about boxing gloves and some pads. You and your girl can take turns and let out some aggresision.

Although I've used different types of machines I purchased a Schwinn Airdyne for my home a few years ago. There simple fool proof and just about imposable to wear out. I picked mine up used at a second hand fitness store.
