are there days where you only train certain parts of your body / only do certain exercises because you simply don’t have the time for a full workout?
my ideal workout means stair climbing, running-walking and stretching. It can well last 2 hours.
Some days I don’t have enough time to do all that. Would it be better to do less of each kind of exercising or just to fixate on one kind?
Two ways:
prioritize your time. If something is important to you then you adjust other things to make time. Such as spending less time on social media aka lemmy.
shorter duration, higher intensity.
For you if you’re short on time id focus on running- walking, pushing yourself to run more frequently than if you had the full 2 hours. The idea is to get your heart rate up higher than normal
