For example I do every day right after waking up a small exercise of yoga. There are plenty of short videos on YouTube, you can find them in specific time measures.
If you are willimg to stay with cardio but a different activity, I recommend buying a bike and going to countryside. You dont need a partner for that, when its sunny you an enjoy a beuatiful view ans it is a quick way of transport. You can buy one even for indoors or go to gym 🙂
