Body-Solid Powerline PSM144X Smith Machine is a fixated, limited range of motion machine. You can only go up, and down. (You lift things aap, and you put zem down) To me, this machine has some flaws. It is fixated, so muscles like your abdominals and hip flexors, don't have to work as hard! Now hear me out, the idea of working out is for health, strength, destressing, etc. But if you are going to say, squat, why don't you do it right to reach maximum benifits from the lift? Any machine that lifts with you, does not allow your accessory muscles to stablize the weight, allowing only certin muscles to get stronger, rather then the whole. Therefor, once those targeted muscles get too strong, injury can occur due to the imbalance of strength.

This machine is something that one would find in a hotel during vacation or a trip, due to it's ease of using. That's some of the pros of this. It can be very easy to use because the machine will do the stablizing work for you, allowing more weight to be used, but at the cost of neglecting other muscles. But it is nice to find locks at certain points incase you fail at the lift and there is nobody to "spot" you. It will not go lower then a certain point.

This really is not something I would reccommend to anyone because there are better buys out there for better equipment setups, for example: a cage (which is a metal box with bars that can be set at different heights to avoid injury) There is also maintence of oiling, or using some type of lubricant (vaseline, wd-40) for the fixation beams. Also, there is a weight cap: it can handle only "X" amount of pounds on the bar, before the bar bends and you have to get a new bar or machine itself.
