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?
Who downvoted you? We can’t all escape our responsibilities for 3 hours, or enough to work everything at a strict schedule.
Yeah, this is bad advice for a comp level, or optimal progress, but for 99% of people the habit of going and doing something is orders of magnitude better than finding every excuse not to go that day.
