You will have several choices of hexagon dumbbells at the time of purchase, so it is important to take a few things into consideration when choosing the ones that are right for you. The first step is to determine what weights you need: it is best to buy a variety of weights to allow for progress in your workout routine, though several weights can take up a fair amount of weight. If possible, buy a kit that comes with the hexagon dumbbells as well as a sturdy stand for storing the weights when not in use. Remember to buy two of each size weights, so one can be used in each hand at the same time.
Once you have determined what weights you need, consider the different features common on hexagon dumbbells. The least expensive models will be very simple, no-frills weights made of iron. The grip will often be smooth, though some feature dimples for added grip capabilities. If you are looking for hexagon dumbbells that will not cost you a lot of money, these are perhaps your best options. If you are looking for something with better grip, consider a more expensive model with deeper dimples, ergonomic handles, or even rubber-coated grips, though you should be careful with the latter since the rubber can work loose or peel.
The least expensive hexagon dumbbells will feature a straight grip, but higher end models will feature a grip with a bulge in the middle. This type of grip will be much more comfortable on the hands, and it will allow you to get a better grasp on the weight during common exercises. This is a good investment, especially if you intend to use the weights daily or otherwise very often.
Some hexagon dumbbells are coated in a plastic covering over the entire weight. This is usually done for smaller weights, and the plastic will protect the weights from damage, but more importantly, the plastic cover will protect fragile surfaces such as wood floors from scratches and dents due to the weights being dropped or moved. If you will be working out at home and do not want to risk damage to your floors, choose these plastic covered dumbbells, but keep in mind that heavier weights are usually not available with a full coating; the plastic can be slippery, so it is easier to lose control of heavier weights that are plastic coated.
