First, the treadmill:
Substitution: Who said that running must be on the treadmill? Streets, fields, Woods and other wide places can be places for you to run. Listening to songs with headphones and enjoying the scenery along the way will make the originally boring running interesting. And you can use mobile phone running software to record the distance, such as splashing, running laps and so on. After a long time, I have saved more screenshots of running, which is really not a general sense of accomplishment.
Second, spinning:
Alternative: mountain bike. Maybe not as good as the spinning bike in the gym. A coach has a strong musical atmosphere, but a mountain bike, put on your equipment and ask a few friends to ride around the city, which is healthy, environmentally friendly and can enjoy the scenery. This kind of experience is not available in the gym.
Third, dumbbells.
Replace: Put a stone in an empty bottle.
Empty bottles of different sizes are not uncommon, just put sand, stones, etc. Reach the weight you need, and a pair of simple dumbbells will be finished. If you really don't like this feeling and feel bad, go to a treasure and buy a pair of dumbbells with the weight you need. In short, you can exercise at home by yourself.
