Another important factor is that a home gym is better suited to a ground floor house, so that it does not threaten the construction of the building and doesn’t create too much noise.

2. Define Your Goals: Each goal has different time requirements per day and per week. You have to consider the type of body that you want out of the exercise. Are you doing it for body toning, to lose weight or for aerobic exercise. That is the most important determining factor to decide upon an equipment as different types of equipment work for different goals. If you are looking for an overall workout, then you might have to buy various types of equipments. Depending on the fitness regime that you are going to adopt, then decide on the equipment required.
3. Think About The Budget: After you have set you mind on your goal, then it comes to the part when you have to buy an equipment at a reasonable price which doesn’t strain your finances. If you are new to exercise, then it is advisable to buy second hand quality used equipment at reasonable prices. It is no use buying expensive equipment as you are not sure you even might want to stick to the same type of exercise. As your budget allows, buy equipment one at a time, adding pieces to your gym. Add with the basic equipments needed to start off, like a set of dumbbells and weights and a quality bench for those who want to add strength or gain body bulk. Or you can add one equipment which you know you are likely to use everyday.
