Try a used treadmill before you buy! Try it again before the buy! Think again, list all the negative points, why you should not buy this particular treadmill, and then finally decide whether to buy it or not! Before that, are you psychologically ready to buy a second hand product- the one used by others? This issue is very important. Hundreds of people are going to ask you this in the future, why you bought this secondhand treadmill. Every time, you need to give them a sort of mini-discourse and convince them, as to what made you go for a used treadmill purchase! If you have made the buy against the wishes of your wife, she is not going to pardon you for lifetime! Take it as a guarantee! There is, however a difference between a used treadmill and the refurbished treadmill. By buying a refurbished treadmill, you have actually bought a new treadmill. In the process, you have saved thousands of dollars as well. But you need to know the art of buying a used treadmill, and you need to take some basic, unfailing precautions. By buying a used treadmill, you have already saved the gym fees. Perhaps a few months fees would equal the cost of the treadmill you have bought. Some used treadmills are sold with a limited warranty as well. Before buying a used treadmill, think of some import parts first. Do not make compromise on the motor. If motor is defective, no amount of assurances is going to save you from immediate future troubles. Have a trial run, and watch whether any additional vibrations are created by the treadmill. And the console of the treadmill needs to give you the correct indications about the speed at which you run the distance and the time. Some consoles have pre-generated workouts. As for the body, look for the treadmill with a long deck. You need to walk or run at full stride that will give you total exercise freedom. Of what material the frame is made? If it is steel, it is better and will have long-term advantages. The minimum size of the deck should be 52. Look out for two important safety features in the used treadmill you intend to buy. First is the automatic stop button. The reason for this facility is obvious. Second is provision for the safety key that locks the treadmill. Let the children use it in your presence and with your permission, till such time they have mastered the procedure well. Again to remind you about the motor, it needs to be a quiet motor! With the grumbling motor, the whole treadmill will grumble!
