Working out at home certainly has its advantages in terms of scheduling and convenience - when you work out at home the gym is always open!
However, there are many potential distractions in the home that can interfere with your training schedule. Therefore, in order to achieve your training objectives you must guard vigilantly against allowing this to happen. If you consistently find yourself putting off your training because of this or that demand from other family members and/or domestic responsibilities, then perhaps a commercial gym is the better option for you. It's much easier to give yourself permission to temporarily let go of your household duties and responsibilities when you're physically removed from the situation.
Although there is a greater variety of equipment at a gym, you can still get just as good a result working out at home with what you have. It's not about having more equipment, it's about how well you can use what you've got. Therefore the initial investment in work out equipment is not as much as you might think. The Basic Workout Equipment section identifies what equipment you will need to get a full body workout at home, categorized by "important to have" and "nice to have".
The Resistance Training Exercises section will show you how to do traditional weight training exercises using dumbbells and tubing. It will also provide some suggested exercise combinations that will allow you to get more done in less time as well as increase the cardio component of your workout.
The Functional Training Exercises section will identify a series of multi-planar exercises that will both condition your body and make it functionally strong. Not only will your body be stronger and tighter, you will feel more energetic and look fantasic!
