Is exercising good in Project Zomboid?
Yes it’s worth it if you have the time to exercise and you’re in a safe area. You can speed up strength training a bit by eating high protein food, like just straight animal meat or jars of peanut butter.
How long does it take to get exercise fatigue in Project Zomboid?
Could be a few hours or more. With standard settings it can take several in game hours (about 4 or 5 in my experience, but I usually sleep through the pain phase and in standard settings you can’t do as many exercises) to go away, so it would take at least that much time in real time.
How do you get rid of exercise fatigue in Project Zomboid?
It seems that the only way to remove the exercise fatigue debuff in Project Zomboid is to wait it out. The length of the wait will depend on how much the player exercised before getting the debuff.
