Adjustable Dumbells

If you haven’t seen these, you owe it to yourself to check around online or run down to your local sporting goods store and take a peek.  If you’ve read my article on old-school adjustable dumbells, you know the ups and downs, and what you can expect if you pick up a pair of these for yourself.  If you haven’t do yourself a favor and take a peek.

Things have come a long way in the past few years.  If you think about a full rack of dumbells, with a range of weight from, say, 10 lbs to 50 lbs, you have 9 sets of weights.  That makes 18 total dumbells, and a total of 540 pounds.

For one thing, that takes up a lot of space.  18 dumbells probably need a rack, and the rack is going to be big.  Not to mention the dumbells themselves.  Further, the most you’re ever going to use of these weights will be 100 lbs at a time.  Think about it - one 50 lb dumbell in each hand.  So all the rest of that iron is just sitting there doing nothing.  Wouldn’t it be nice if you could use just a portion of that 50 lb dumbell and not have to pay for all the extra dead weight?  Last time I checked, steel is expensive.  It’s a shame to pay for something you’re not using.

Interestingly, you can do exactly that.  There are adjustable dumbells that allow you to do just that and are still easy to change and modify along the way.  All it takes is a click here and there, or the turn of a dial, and the weights that you want to use stay on the bar.  The ones that you don’t want will sit nicely on their stand while you perform your exercise.

These weights allow you to do exactly what we discussed before - have a 100 pounds of weight and use any combination of weights contained therein.  Now, they’re expensive, so don’t expect to pick them up for the price of a standard set of 100 lb dumbells.  But you’re really getting the use and functionality of 540 lbs of weights, so you would expect them to cost a little more.

These probably aren’t the best solution for a commercial situation where you have a clientele who are using the weights.  In that situation it’s an advantage to have more sets of independent equipment that people can use.  For the home gym, they’re perfect.

If you look around today at sporting goods stores or surf some fitness websites, you’re going to see a lot of modern adjustable dumbells that have different types of locking mechanisms to add and remove plates.  These mechanisms do not require that you actually take a plate off, rather, you simple select the weight you desire and lift.  The plates come with it.

Contrast that with our friends to the left here, which although are still a new set of adjustable dumbells, are very old technology.  Old, inconvenient, and cumbersome.

If we look at their construction, it’s quite basic.  Two bars that are threaded on each side to accept a collar.  This collar screws onto the bar and compresses the plates against a shoulder that rests just outside the grips.  You can add just about any amount and configuration of plates that will fit on each side of the grip.  It’s so simple it’s almost genius.  But not quite.

The problem comes when you want to change weights.  Don’t get me wrong, the whole contraption is very secure and safe.  There’s probably no safer way to secure weights to a bar.  The problem comes when you want to shuffle weights.  Adding plates onto the outside is relatively simple, as long as you don’t mind having them stacked randomly.  those of you who are OCD and demand that your largest plates be on the inside will soon find this to be an unacceptable situation, and start removing smaller plates before you put on the larger ones.  This takes time, and is tedious.

When taking plates off, you can’t simply strip off the 5 lb plate on each side if there’s a smaller one closer to the collars.  You’ll need to take the smaller weights off the adjustable dumbell, remove the larger one, then add the smaller plate back on before tightening the collars.  Again, messy.

Working out is enough of a hassle that I like to minimize as many interruptions as possible to get maximum return on my time invested.  I think most people will agree.
