Question: Does the 150+ lbs ship in one heavy box or does it come in multiple lighter boxes so you can move it safely and more easily into your basement?
Document: The problem of traditional dumbbells is the need to have multiple pairs if you want to minimize time when changing weight, which takes up space. So I started comparing those adjustable type and after doing my research and physically comparing them, I settled on the Ironmaster.Unlike most other adjustable sets, Ironmaster's come with a lifetime warranty and were adjustable from 5-75lbs as compared to a lot of others with lesser weights.The handles are solid steel and weigh 5 lbs and are very well made. They are chrome plated with the knurled steela for better grip and are no different than traditional dumbbells.
You could load 75lbs on both dumbbells put them on a dolly throw the stand on there and move them right along.So what makes these the best?I'll tell you what my number one criteria for adjustable dumbbells are, and should be yours too.1) Do they go heavy enough?2) Are they compact enough for the core exercises?3) Safety/reliability4) Do they change weight quick enough for all exercises?The rest I simply do not care about. These happen to be the most aesthetically pleasing dumbbells as well, in my opinion, which is just a bonus.
For quite a while I was interested in the Bowflex adjustable dumbbells, but I'm really glad I found out about the Ironmaster's set before I made my decision to buy such a product.The Bowflex set allows you to lift with up to 52.5 pounds per dumbbell, which is fine for those who don't do heavy chest and shoulder presses, or heavy dumbbell rows; but for those who really want to push themselves hard, there is nothing like the Ironmaster product, since it allows one to lift up to 120 lbs per dumbbell with the add-on kit.
ive had these for a week now. i just challenged some friends who have powerblock sport 9.0 to a contest to see who could do drop sets (by 5 lbs) quicker. i won easily. i set up the IM's with five 5 lb plates on one side and four 5 lb plates on the other side with a 2.5 lb plate on the inside. a 57.5 lb dumbbell and the 2.5 lb offset was virtually unnoticeable. after one set, all that is needed is to remove one plate from the side with the 5 plates...after the next set one plate from the other side and so on..... meanwhile they have to remove the handles and add or remove the little adder weights on their powerblocks, reinsert the handle and the pin.
This is what you get from Ironmaster products. Forget all the other adjustable dumbell systems. Using the Ironmaster dumbells may take a little longer to switch from one weight to another but, it is well worth the minimal time difference. Bowflex, Bayou, PowerBlocks, Universal Pak, etc. simply pale in comparison to the Ironmaster.The only dumbell system I would own instead of the Ironmaster would be a complete set of individual cast dumbells and the appropriate rack (which I have owned in the past). However, having 30 separate dumbells which weigh a total of 1,200 lbs takes up a lot of space in one's home, and can become a little cumbersome to move about.Before purchasing a set of adjustable dumbells, I urge you to check out the Ironmaster website.
I actually have the bowflex for lighter weights (&lt;50lbs) and use these for heavier weights (>60) since I bought the expansion set.If you can only afford to have one set of weights, don't need more than 52.5lbs AND don't think you'll ever drop them, go with the bowflex. However, if you expect to go above 50 lbs and you think that someday you may screw up and drop your weights, you can not go wrong with these ironmaster.
If you want adjustable dumbbells, a stand, and a system that will almost certainly not break if you drop them, look no further.Pros- Weights levels are fairly easily changed.- There are no little clinking noises when you move the weights (i.e. they are SOLID)- Stand only takes up as much space as necessary, not more.- Can go up to 125lbs with the expansion- Extremely well built; you will likely have these for decades.Cons- Not as easy to change weight levels as the units with the switches.
I like them for their sturdiness and lack of rattling especially when using heavy weight. In addition to the IronMaster, I would buy a cheaper set of adjustable dumbells with a lower maximum weight (50lbs maybe) that could be easily adjusted in 5lb (or smaller) increments to use for curls and kickbacks etc...and stick with the IronMaster for the heavier weights, where I really don't mind the extra minute of rest to change the weight! In fact, I think I will sell my PowerBlocks and get a set up like this, and have some money left over for Muscle Milk!
They have a LIFE time warranty on their dumbbells which come with a stand/rack included.For super heavy lifters ironmasters are expandable to 120 pounds per hand and beyond, I guess 160 pounds or something.Finally, they are cheaper on their home page than amazon (sorry amazon).
ONE SUGGESTION: Since these are more suitable for heavy work than other similar products, how about designing a model that -begins- at 20-25 lbs?,  the lightest that many men ever use. The permanent plate could be built bit  higher than the add-on plates, to allow easy plate-changing while the db is on the floor.
