DUMBELL-has smaller rings and has a shorter rod\n       -can be held by a hand\n       -usually for bicep enhancement\nBARBELL-greater ring diameter and is heavier then the latter\n       -usually held with two hands

You need to do dum bell (unilateral) work for your arms or any other body part if this is happening.DOMS(delayed onset muscle soreness) is a result of microtrauma(not lactic acid that's cleared from the muscle almost immediately).This is tiny tears in individual muscle fibers.If your experiencing more soreness in one biceps group as opposed to the other you're somehow compensating.Doing DB curls will ensure that you can work both equally.Let's say you can do ten reps with your right arm with 50#DBs and eight with your left.Do each one until positive failure without a set number in mind.If you get 8 with your left and ten with your right you'll hit each one with equal intensity.Right handed people are stronger in their right hand for neurological reasons and not by virtue of mass alone.\nDo your DB sets after all of your barbell work.

If you're not going to have a spotter, you  might be better off finding a gym which has machines instead of free weights.\n\nMachines are safer to use if you don't have a spotter.  You can't drop the bar on your chest on a bench press machine. The worst thing you can do is to drop the weight stack and shatter the weights, but I've never seen this happen.\n\nMe, personally, I prefer the feel of free weights, but a lot of times, I don't have a spotter either, so I had to compromise and used the machines. If you're just starting out, machines and free weights will give you the same results.\n\nGood luck.

The adverage lifter should not own many dumbells.  People yap about muscle group isolation but I'll bet you're into more of a full body work out anyhow.  Most people shouldn't be into isolation until very advanced levels and by then you probably spend alot of time at a gym and you can use their stuff for free.  So like I say, don't buy them.  \n\nYou have to be really into lifting before you can use at a level that would benefit you any more then a standard bar lift and they cost a fortune since you're constantly outgrowing them.  The only advantage for the adverage at home lifter, and it's a narrow one, is that you typicaly don't need a spotter so you can work out alone.  But the only reason you don't need a spotter is because you're not lifting as much weight.  If you're not lifting as much weight on a dumbell are you getting a better work out then with a bar?  I don't see how that could be possible.

Get on a pec deck machine at the gym. It should build up both sides as the pressure to both sides is usually the same. Otherwise, do dumbell flies on the bench but use only your right arm or more weight on right.\nBecnch pressing should develop both sides too.\n\nAre you sure the difference is really noticable though? I've never personally noticed a great imbalance in pecs unless you have a job that somehow over-develops one side, in which case I'd expect a huge imbalance in your arms too. Plus, you're human, your sides don't match.\n\nIt's curious that the wrong pec is developed though, why not visit a docs to check it out, it's probably nothing but you are obviously concerned so get it checked by a professional?

take some dumbells and stand up and just do some arm curls.  if you sit down you will only work out your arms.  but if you stand up you work both.  good luck

because in everyday life, you do not use muscles in isolation, it is more beneficial to use multiple muscles at once when weight training also, for equal strength buildin, so one is not compensatin for the other, they are working in unison - hope that makes sense! :-)

Dumbells.  Very effective, cheap, and easy to put away.

A Type 1 Lever is where the pivot (fulcrum) is between the effort and the load. In an off-center type one lever (like a pliers), the load is larger than the effort, but is moved through a smaller distance. i.e. a hammer\nA Type 2 Lever is where the load is between the pivot (fulcrum) and the effort. i.e. a wheelbarrow\nA Type 3 Lever is where the effort is between the pivot (fulcrum) and the load. i.e. tweezers

I think you should go with slightly lower weights, maybe eight or five pounds. I work out a lot and even when im just using 12 pound dumbells i get bulky in my arms pretty easy. Using a lower weight with more reps would help with toning without making your arms look bigger. Thats just me might be different with you. My weight usually fluctuates about five pounds but i weighed in yesterday at 128. Im 5'4.

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!

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.

Powerlifting. Bodybuilding is more modeling than an actual sport. Powerlifting has to do with actual physical ability, which is what sports is all about. Strength can be measured objectively and has real-life applications. On the other hand, just flexing your muscles won't help you that much, unless maybe it convinces other people to do things for you.

they are used to convert a relatively small force into a greater one, though it's important to remember that they don't do ANY work.  one exaple is a lever and fulcrum, with which a small force can be applied to the longer end of the lever to lift a weight would provides greater resistance than the small force, without the use of the lever.  this is possible because the small force must be applied over a greater distance than the distance the weight will be lifted.
