I was looking at Powerblock, as they are the only ones I can find that doesn't require oversea shipping. The price was just ridiculous though, seeing as how you need to buy the basic 9.0 set and then the 9.0 II set to have enough weight to work with.
I've tried a smaller version of the Bowflex, and I agree that they do not seem to be very solid.
I don't remember Navy ships offering much in the way of personal storage. I'm sure you could bring a pair of DB's, but there'd be little room for anything. Of course there's no need since every Navy ship I've been on already has exercise equipment.
i own both the powerblock 130s and the ironmaster 120s- I say the ironamsters r much better to that hardcore mentality us heavy lifters have. I think the powerblock feels a little more balanced and is a little faster to change, but also kinda seem to delicate to drop. with the ironmaster, u will require more stabilzer strength in my opinion.they do not rattle and u could slam the $#!^ out of em after a good heavy set. I vote Ironmaster.
Most adjustable dumbbell sets (at least the cheap ones) effectively require you to have the base tray that comes with them, as it holds the plates in position so you can drop the handle in and adjust them. This is a major drawback as far as portability (and an even more major drawback with the cheap brands that have a plastic base.
From the looks of it, the powerblocks don't have this problem. Is this true?
I'm currently on a supply vessel in the North Sea. We have exercise equipment here, but unfortunately no free weights. There is a multi station kind of thing which is decent enough for a few things (lats, arms), but there is no way to really train legs or even shoulders.
I am looking for something that won't take up too much space, which is why the Bowflex seemed ideal. After reading the comments here I have reconsidered.
I've never used them outside of physical therapy, and don't think I'd like them much for pushing heavy weights, but they should provide you with more flexibility to your workout. Another bonus is not having to worry about compensating for swells.
The price is similar to the adjustable DB's, will probably be easier to store, and will certainly be a hell of a lot easier to carry around. You could probably get away with safely storing the base in the gym (no one would know what to do with it) and keep the bands in your private storage.
