Why does title of this article mention Housewives and Athletes? Brace yourself for answer: Because training protocols for both are exactly same! "How can that be?" you ask. "Is author of this article on drugs?" "How can an athlete and a housewife train same way?"
Here is your answer: Because each of them works diligently towards their respective goals using same time-proven training techniques that you are about to learn. The goals of an athlete may be different than those of a housewife, but science behind training program is exactly same.
EXERCISES
If your goal was to bench press heaviest weight in history would it help you to take ballet classes? If your goal was to have a trim, toned body with a low level of bodyfat, would you get a lot out of Power Lifting classes with a squad of 350 lb athletes at 'Bruno's Iron Body Weightlifting Dungeon'?
The point is that you have to train for what you want out of your exercise program! Don't choose exercises out of a magazine just because they worked for author of a particular article. Don't do "classic" exercises at gym just because everyone else is doing them.
Determine what your goal is, decide which exercises and which training programs will get you to your goal, and then just follow your program. This is pretty basic information, but you may be surprised by how many people just follow crowd, which will get you exactly nowhere.
FORM
Once you have your training program ready to go, you have to do it right! If your program calls for eight 30-second wind sprints in 5 minutes, guess what you have to do?
If your program calls for picture-perfect free weight squats, bench presses, or lunges, how should you do your free weight squats, bench presses, and lunges?
You have to get your training program from a reputable, trustworthy source, such a personal trainer, or a friend or family member who is in very good physical condition. Once you have determined that your source is qualified to tell you how many wind sprints to do, or proper way to do lunges, then you need to do exactly that.
Too many people get "distracted" during their training sessions and just end up going through motions. During each and every exercise or activity, your form should be perfect, your concentration should be fierce, and your effort should be maximal.
Safeguard your health as well as your fitness goals by doing things right way. You'll achieve maximum results, with minimal risk or wasted time.
SETS
How many sets of each exercise should you do? No doubt your favorite fitness magazine has instructed you at some point to do 3 sets of 12-15 repetitions. That is good advice in some instances, but not in ALL instances. Who came up with that number, anyway? The proper number of sets to perform of each activity depends on activity itself, what your training goals are, and where you are at in your training program. 3 sets may be perfect in beginning, but later on down road, you may need more or less than that.
