What is hydraulic and air pressure machines?
This machine category doesn’t have a weight stack either. Hydraulic and air pressure machines have a series of pistons that create resistance by pumping oil, gas, or fluid. These machines are fine — some are very well designed —but some exercisers don’t feel motivated when they use them because a weight stack isn’t moving up and down or steel isn’t clanging. (Some people have quirks about working out.) All you hear is a sound that’s similar to a can of hair spray in action. Gyms that offer 30-minute circuit programs often use these machines.
