Yes, it is possible to use a desk and a stand-alone ceiling fan in your home gym. In fact, many people prefer to use a desk fan because it's easier to move around and it's more efficient than a ceiling fan. There are a few things to keep in mind when it comes to using a desk and a fan in your home gym. First, make sure that the fan is powerful enough to adequately cool the space. Second, be sure to position the fan so that it's blowing air directly onto your body (rather than across your body). And lastly, be aware that using both a desk and a fan can result in increased noise levels, so be sure to keep that in mind when planning your workouts.
