I want to get into exercise for my own personal well-being and fitness, and I don't want to do 'target' exercise (which I know doesn't work) but rather I want to improve my physical endurance so that I feel less tired during the day.
I would like to fit this into my morning routine, but I know that I occasionally oversleep, or have to prepare something before going to work, and sometimes I have as little as 5 minutes to try to squeeze in an exercise routine. But I would like to do something regularly so that I can make it into a habit, with the goal of doing more as I improve.
What exercise routine can I fit into a 5-minute morning exercise to help improve my physical endurance? Currently, I'm using sit-ups as my go-to exercise (cross-body, not arms behind the head) and considering adding push-ups too, but is there anything better? Or something that could exercise parts of my body that sit-ups might miss?
Keep in mind I don't have any equipment, and my apartment space is very limited, plus I want to be able to do this routine even if I have to go away on a trip.
I plan on doing the same exercise in the evening as well, and to increase the time I do my exercise steadily as I improve, but to do that, I have to be able to fit a bare-minimum routine into my morning first.
