If the purpose of your fitness program is to get a stronger and leaner body then there is nothing quite like resistance training to assist in reshaping your body.
There are various different types of resistance training programs but they all center around the use of weights, machines or your own body weight to add resistance to a workout routine.
This additional resistance forces the body to grow and at the same time, burn fat.
Depending on what results you are after, resistance training can be used to develop a bigger body, as you might see with bodybuilders, or it can be used solely to gain strength without the focus on weight gain.
Naturally this weight gain would be lean muscle but there are some people who have no desire to gain additional muscle size.
Many women are reluctant to enter into a resistance-training program for fear that they might develop big muscles and lose their femininity.
This does not have to be the outcome of a resistance-training program.
Resistance can be used just as effectively to reduce body weight in the form of fat and also to create a leaner and sexier body.
Fortunately more people are realizing that resistance training is one of the fastest ways to reshape a body no matter what your goals are.
In addition to the reshaping of your body and the reduction of body fat that comes about from a successful resistance-training program, there is the added benefit of better aerobic fitness.
Some people are still of the mistaken belief that resistance training does not help with aerobic fitness but this is not true.
A good resistance-training program will also help with aerobic fitness.
It really depends on the amount of energy you exert during your exercise routines and by simply adding speed to your routine you will be increasing your aerobic fitness.
That speed can be in the time it takes to perform an exercise or by reducing or eliminating the rest time between exercises.
