For decades my wife has taken 5 or 6 400iu Vitamin E tablets before doing unaccustomed exercise, moving, extra gardening, etc. with no stiffness or aches after. If she forgets to take them she has all the normal problems that follow these actions. She then has to take two to three times the dosage several time to get rid of the aches. For some reason I am one of the lucky ones and rarely have any aches following an unaccustomed exercise but the vitamin E works well for her.
