Fitness can be really important based on the kind of physique that you might be thinking of going for, but people tend to misdirect their focus when they are attempting to be as fit as possible. A big part of the reason what that is the case has to do with the fact that they feel like lifting weights is the best way to get fit, but if you think about it lifting weights is quite limited when it comes to helping you with an absolutely crucial aspect of getting fit which is to strengthen your core in some way, shape or form.
Your core simply does not get engaged when you light weights, and if you want to rectify this by focusing on your core a bit more at any given point in time then you might want to do planks every so often. Planks are great since they really tense up your core in an amazing way, and doing them for an extended period of time can burn a lot of fat from your stomach area. You can even do them on a party bus service Phoenix which proves that they are a very versatile form of exercise that can be performed regardless of where you are or what you might be doing at that point.
You should ideally be able to do planks for at least two minutes if not more than that. Generally speaking planks stop being effective once you get to a point where you can do them for three minutes or so. Once this level of fitness is reached you can move on to other exercises that would help you in their own way all in all.
