I buy these when I want to start work out again . call on my past excuse -lrb- the gym too far , take too long to get there , in , out , and back , et al -rrb- , I know the most effective way to tackle that be to bring what I could to I . also , I live in a apartment so any and all concept of build a actual gym , couple with the fact that I do not waltz around lighting cigar with $ 100 bill , lead I to find a solution . and that solution ? powerblock ! while obviously not provide a full gym , you can do a lot with free weight and cheap weight bench that you can tuck away somewhere . not only be these effectively cheaper than buy a entire set of weight , they be not incline to punch a hole through the floor , annoying my downstairs neighbor and eliminate any hope for my security deposit . they can also be easily stow away behind the couch , under the desk , or wherever you can fit two 45 lb dumbbell . the one and only complaint I have for they be that they do not have a 2.5 jump -lrb- 22.5 , 32.5 , etc -rrb- but they can do 7.5 . I know I be nit pick here but it be nice when you be push to not have to jump 5 lb . also , you can max they out fairly quick with thing like press make it necessary in no time to throw down for the expander set . other than that , though , they have be the best fitness investment I could make ! if you or anyone you know want to find a easy solution to bring the gym home , I would recommend these over any equipment out there .
