The research problem is that there are many coaches who do not prefer the variety in the exercises to develop the physical abilities and depend mostly on weight lifting without the other training devices .In every research, there a problem which face the researchers according to the specialization.

The problem here which motivates the researchers to conduct this research is a training problem in the field of the explosive capacity .

The two researchers believed in the scientific research as a scientific means for accessing the facts.

Therefore, the two researchers aimed to study the priority of using weight lifting exercises or biometrics to develop the explosive capacity of the legs muscles of young boxers at the age of 18-20 .

The research aims to prepare exercises of weight lifting and biometrics for young boxers ,joining the Alshurtaa sport club at the age of 18 -20 years ,totaling 20 players.

.The research sample is divided into three groups .The first group uses weight lifting exercises .

The second group uses biometrics exercises.

The third group .

The third uses the regular exercises of the coach.

After series of procedures , the two researchers concluded the following : 1.It is possible to depend on exercises (weight lifting , biometrics ) as effective methods to develop the explosive capacity for legs, research sample for boxers at the age of 18-20 years.

2.

Exercises (biometrics) have a big priority to develop the explosive capacity for legs muscles , for research sample of boxers at the age of 18-20 years
