Physical Features
Though dumbbells are fairly simple, there are a surprising amount of physical features to be aware of.
Shape
Dumbbells usually either come with hexagon shaped heads or round heads. Round heads are sometimes favored in gyms because they’re considered Olympic dumbbells, but in most cases you’ll find hex dumbbells. Hex dumbbells are much nicer because they won’t roll away from you when they’re set down in between sets.
Materials
There are many materials used to make dumbbells but the weights themselves are usually made of iron; however, they can be also be made from steel in some instances. The only problem with iron dumbbells is they can rust over time due to sweat or humid gym atmospheres.
Many popular brands of hex dumbbells come with a rubber coating around the ends of the dumbbells. Rubber ends promote personal safety as well as the safety of your surroundings.
Neoprene and vinyl are often used on smaller dumbbell sets ranging between 1-10 pounds. They offer a softer feel with a decent grip but the material often smells bad and will eventually rip and peel off your weights at some point.
Mold
Most dumbbells use a single pour mold which eliminates any seams or burrs, but it is prudent to check your dumbbells just to make sure. Any seams or burrs can catch on your skin resulting in calluses and/or cuts on your hands.
Are Dumbbells Right for You?
It is hard to argue that dumbbells are not right for you given their versatility, but there are a few things to consider.
Space
If you’re thinking about going the traditional dumbbell route you are going to need some space. Even if you skip a few weights you are looking at a couple feet of space taken up. If you occupy a small living space a dumbbell is likely to take up valuable space.
Safe Use
If you’re exercising for rehabilitation purposes or experience other special needs which may cause loss control of your weights, free weights may not be for you. Certain physical conditions could cause weights to drop or slip from your grasp, resulting in serious injury and/or damage to personal property.
Workout Style
In most cases dumbbells are a slam dunk for personal workout routines because of their versatility. A few exceptions may be if you’re doing a mostly cardio-based workout; in that case you may want to invest in a weighted vest or ankle/wrist weights instead of dumbbells. If you’re into more functional training, a kettlebell may be better suited to your needs.
