If you have a large home, chances are - you'll have the freedom to buy any kind of home gym equipment you want. But if not - it's important to focus on the essential tools you actually need first, so that little room goes to waste.
If you have access to a garage and don't mind parking on the street, you are one of the lucky ones. Garage space gives you access to more than enough room to build your own setup. If you don't a garage but you have a backyard or driveway, buying portable equipment that can fold up will be great. Equipment that can be stored easily is a huge plus for anyone.
If you have little to no space available indoors or outdoors, then your choices may seem limited. But there is still hope for you! Some fitness equipment is designed to be be light in footprint, but high in functionality. This includes portable essentials like glute or strength bands for resistance training.
Another important thing to consider is that many exercises involve heavy weights and large machines, like treadmills. These can damage the floor of your space if not set up correctly. If you're training on carpet, you could indent your flooring if under equipment that is too heavy. If you're training on tiles or concrete, dropping weights can crack the ground. In this case, you'd need to look at buying rubber gym flooring tiles as well.
If you're looking for a compact, easy solution - a functional trainer could be your best option. They take the pain away from home gym shopping by offering users an all-in-one home gym experience. Most functional trainers come with a bench press station, as well as pulleys to work out with cables. This allows you to train all your muscle groups with one machine - and usually they're not too expensive.
While space is a huge factor to consider, everyone has options to train from home effectively.
