Creating a home gym is a solution to an expensive gym membership. If you go to the gym during the peek hours chances are that you will have to wait your turn to even the equipment. If you have a family to get home to this could a problem. You may not have the time to kill waiting on the equipment you are paying for with the membership you paid for.
Have you ever thought of all the germs lurking around the gym that you are being exposed too? They are everywhere. Even if your gym offers sanitation wipes that doesn't mean that everyone using them. The restrooms and the shower areas is another area for concern. Because there is no way to avoid the germs in this area.
With a home gym you can ware what you want to and you do not have to worry about who is watching or judging you, and if you have pounds to lose you will not feel embarrassed when you choose to create your own gym.
Knowing what equipment you will enjoy and use is a key factor to consider before investing your money into something you will not use. Think about what type of exercise you enjoy doing. If you enjoy walking you could invest in a good pair of walking shoes and a treadmill. For building muscles and toning muscles a good stationary gym would be a good choice.
My advice would be to start out small with a good mat, good fitness shoes, a stability ball, free weights, and good exercise dvds. Then when you see that you will stick with exercising then add equipment as you progress.
