To be effective, an exercise program must be
a. uniquely tailored to every person
b. maintained at a constant level of difficulty
c. applied generally to whole-body fitness
d. constantly increasing in difficulty

To be effective, an exercise program must be (a) uniquely tailored to every person. This is due to the fact that each person has a unique body as well, what could be an effective regimen to one person may not be as effective as another. Each person's health has to be taken into consideration as well since some health issues may need special attention.

10/10 recommend bring pads/tampons with you no matter what. im 16 & i’ve had mine since i was 12 and they’re still it regular, but id suggest using the glow app, many women use it for fertility reasons but i use mine specifically for the period tracking portion and it guesses when your next period will most likely be for the next two months. i dont believe theres any way to delay your period, so id say hope for the best but make sure to bring all of your stuff just incase. have a good cruise!
