what is the difference between weights and dumbbells?

weights is just a general term i.e. "i done weights today" meaning i done weight traning today\ndumbbells are the actuall little handlebars with weights on each side that you do bicep curls with. no matter what size they are they are all called dumbbells.

high weight low reps will build more bulk, whereas low weight high reps will build more strength and endurance.

Mass is a direct measure of an object's inertia, and the strength of its gravitational pull. More often, we find it easier to say that mass is a measure of quantity. More mass = more interia, so it works out.\n\nWeight, the way we think of it, is a measure of the net downward force an object undergoes when placed in a gravitational field ("down" meaning toward the source of the gravitational force in question). On Earth, weight is a measure of the effect gravity has on an object.\n\nSince more mass = more for gravity to pull, objects with more mass also have more weight (at the same location in the same gravity field), so we generally use weight and mass interchangeably, and this doesn't cause too many problems.

you can get a complete workout with a $40 set of dumbbells and a $10 stability ball.  if you're really strong, you might move up to a 300lb weight set and a bench.  hell, you can get a decent workout with nothing but a yoga mat and some knowledge.\n\nwhat's the point?  you can get a great workout with any system.  the one that works best is the one that you will use REGULARLY.\n\nthe major drawbacks of packaged systems like the solo/bowflex are that they're ridiculously expensive, you can't add weight if you max out on an exercise, and machines in general limit your range of motion- which means that your form is always correct, but you never have a chance to engage stabilizing muscles.\n\nif you have the money and space for one of these systems, consider buying a weight set, power rack, and bench- and spending the balance hiring a personal trainer to walk you through proper form & set up a program.\n\nanother comprimise would be plate-loaded machines aimed at weightlifters, like those from powertec, yukon, and many others.\n\nyour best option would really be to find somewhere local to try them out for yourself & figure out your own preference.\n\nsummary:  no bad option, but the tv-ad systems are more expensive and feature-limited than pretty much any other choice.  if you dig 'em, though, go right ahead- the best fitness solution is the one you hit several times every week.

weight is measured in pounds and mass in kilograms.  Mass is independent of gravity but weight is not.  as far as them being alike i guess people commonly use them both to measure if they are fat or not.

The mass is a property of an object, a fundamental measure of the amount of matter in the object. The usual symbol for mass is m and its SI unit is the kilogram.\n\nThe weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton.

Weight is the amount of force on an object and mass is the amount of matter in that object

When they say muscle weighs more than fat, they are referring to its density. Muscle is denser, and therefore it takes less of it to reach the same weight as an amount of fat

..also they're measured in different units.\nVolume is measured in cubic units (m^3, ft^3 etc), whereas  weight is measured in units of Force (Newtons, or foot pounds)\n\nYour volume is fixed (unless you have a large dinner) whereas your weight varies depending on your altitude. You actually weight less at the top of Everest than you do at sea level.\n\nIt should also be noted that weight and mass are different.

The previous answer is not quite true. Indeed they are not the same. Weight is a measure of force, whereas mass is mass.\nHowever, you do not weigh the same everywhere on earth, although you would be hard pressed to tell the difference.\nYour weight at the top of everest, for example, is less than at sea level, because the force being exerted on you by gravity is less, allbeit only by a small amount.\nAlso, weight is a unit of force, whereas mass is not.\nMy weight may be 100kg, but my mass is (approx) 980N (at sea level), so weight and mass are actually never equal

For calculating weight you will be needing the specific gravity or bulk density of the material it is made of.\nElse you need a weigh balance.

Dumbells help your smaller(support/stabalizer) muscles grow and strengthen! While the Barbell hit the main muscle groups! Dumbells are the tools used for your body; like the tweeking of an equalizer on a sound system or, the right seasoning on your favorite dish! It defines, what bodypart you've been working on! Barbells are the 'Pit Bulls' of body building! Use correctly, they can blow up the main muscles of any body part! Use correct form at all times!

All is clear once you understand the difference between mass and weight.\n\nIf you are not sure, look here:

If you placed 1lb of muscle next to 1lb of fat, the fat would be 2-3 times the size of the muscle. Muscle doesn't weigh more than fat, it is just more dense. HTH : )

easier as long as you realize that your weight will vary (due to water and muscle mass) and not get discouraged.  remember as you gain muscle mass, muscle is heavier then fat.
