Sometimes, your 'life-style' can be a factor that aggravates the jewellery in your piercing. More often than not these activities are infrequent enough not to cause any real problems. Infrequent exercise might not be a problem, but regular and vigorous activities can aggravate the jewellery in a fresh or healing, or even old and healed, piercing. Withholding from, or temporarily limiting the activities, until the piercing has healed well, can help it last longer. This applies to the type of jewellery you use for your initial piercing. Some jewellery will 'stick-out' more where it 'sits' on the body and will have a greater chance of being 'caught', snagged or 'banged' into.
Location should affect the choice of jewellery chosen for use in the initial piercing. Proper jewellery sizes and gauges are important decisions to make prior to piercing. Examples include using a 22mm long barbell for an eyebrow piercing, which is ridiculous, unless a very angry Hulk fancies any more body modification.
The size and shape of the area to be pierced should be taken into account. Any good piercer will thoroughly check the area before piercing, and help the customer decide on appropriate jewellery before performing the procedure. Customers should be prepared to accept the fact that they might not be able to successfully 'have' a piercing in the area of their choice, and in the manner of their choosing. By all means get a second opinion; then get a third or fourth or fifth, because if five good piercers think a piercing can be done there, then any one of them is capable of doing it. But if five piercers advise you against doing it, its probably best not to.
Give yourself enough time that you can dress appropriately; for example, avoid getting a navel piercing, then zipping yourself back into your skin-tight, all body lycra jump-suit to leave the studio. Obviously it's a bad idea to wear skin tight, all body lycra jump-suits when going for any piercing below the jaw line (I'm assuming that the neck line of your skin tight, all body lycra jump-suit is quite high). You get my point. That goes for accessories too; like huge belt buckles
