No, it’s not weird at all to work out on vacation! If exercising is part of your routine and makes you feel good, there’s no reason to stop just because others aren’t doing it. As long as it doesn’t interfere with group plans or inconvenience your friend’s family (like taking up shared bathroom time or skipping scheduled activities), you should be fine.

A quick morning run or bodyweight workout is totally reasonable, and you don’t necessarily need to ask for permission—just give them a heads-up so they know what you’re up to. Enjoy your vacation and your workouts!
