In natural contests, the testing protocol ranges among organizations from lie detectors to urinalysis. Penalties also range from organization to organization from suspensions to strict bans from competition. It is also important to note that natural organizations also have their own list of banned substances and it is important to refer to each organization's website for more information about which substances are banned from competition. There are many natural bodybuilding organizations; some of the larger ones include: MuscleMania, Ultimate Fitness Events (UFE), INBF/WNBF, and INBA/PNBA. These organizations either have an American or worldwide presence and are not limited to the country in which they are headquartered.
Once you feel comfortably balanced, contract your quadriceps and gluteal muscles and lower your body slowly. When you reach the point where your upper legs are just below parallel to the floor, push back up to the top without “locking out” and repeat the movement. Make sure to keep your abdominal muscles tight to protect your lower back, and keep your head up and your eyes fixed ahead as you perform this exercise.
Lastly we come to full-body workouts. The 5 x 5 program could also be considered a full-body workout program to a degree, since you work almost all the major muscle groups with the three exercises you choose. But, true full-body programs will provide one direct exercise for each muscle group - quads, hamstrings, chest, back and shoulders (arms are worked when doing chest and back).
You should also have everything you need for simple workouts. Especially if you plan to hit the gym nearly every day, it's a good idea to have some equipment for those rainy days when leaving the house isn't an option. And let's face it: Buying some basic workout items will make your jump into the fitness world more fun. This might sound trivial, but having clothes you like can influence your desire to train.
