Suggested correction: Many people buy another toothbrush to take on trips and since they were supposed to be going away, they probably decided to use them at home, as if this was their trip.

The whole point of the mistake is they say they have always shared a toothbrush. So why would they use separate on a trip?

Answer: After running the marathon for Marshall with no training, he's allowed to ride the subway for free. While sat on the train, the muscles in his legs start to seize up after the marathon to the point it is painful to move his legs. This is why he can't move them. It's the same reason your body aches after a good session at the gym the day before.

Answer: Barney ran a marathon without any training and over exerted his muscles. While he was able to walk after, later his leg muscles gave out and he couldn't move (or more likely stand). It is not uncommon when one works out too much to be sore the next day, even if they feel okay afterwards. Thus the saying "I'll feel that in the morning."
