Home gyms require attention to certain details while observing the general condition of the unit over time. The main preventative maintainance items for most home gyms is to keep the gym clean and dust-free and ensure that the guide rods and pulleys are lubricated. As with most mechanical machines, dust, lint, sweat, and dirt affect the overall performance of the gym. Reqularly, wipe down the gym to remove any dust or sweat. A mild detergent and a clean rag will do the job. Most home gyms also require lubrication of the guide rodes (the two rods that the weight plates slide up and down on). Most manufactures recommend a wet silicon spray or lithium grease to be used. Check with the owner's manual for the manufacture's exact recommendations. Most home gyms require lubriction only once or twice a year or whenever the guide rods seam sticky or rough when the weight plates are sliding up or down. Pulleys can also be lubricated with silicon spray if sticky or squeaky.

On a regular basis it is a good itea to thoroghly inspect the gym. Check the cables for imperfections. If you find the cable is fraying, pinched, creased, or starting to seperate in places, it is recommend that the cable be replaced. Also check the slack in the cable tension. Some cables can stretch out over time, if there is a lot of slack make an adjustment to tighten up the cable around the pulleys. When cables become too loose, it can cause a slight gap at the beginning of a lift where there is no weight for an inch or two. Loose cables can also come off of a pulley and get stuck between the pulley and the steel frame. If the cable is pulled while in this stuck position, it can cause the cable to fray or become pinched. Check with the owner's manual for places to adjust the cables on your gym.

Check the gym for stability regularly by ensuring all the bolts are properly tightened and that the gym is level. Make sure that the gym is functioning properly before engaging in any exercises.
