I have these dumbbells as secondary to the 5-50 lb. Power Blocks I have only a few weeks before. I found the first product so much that I bought, the more easily as my wife and I together can lift.   These are very easy to use and surprisingly compact. I went to the fitness store and looked upon them and the Select Techs side by side and was surprised at the length of the select Techs. I am of the opinion that the goods are not for women on how long the bar is for all the weights.   Although this system is a little strangely shaped (block) It is much more compact and thus easier to manipulate. It is true that it takes a little time to make a comfortable grip for a few exercises (like the things behind the head), but if you know what works for you, the system makes lifting easy.
