Fitness is the key for the overall performance of the athletes. Fitness is the product of exercise and training. Fitness is an important implication in the general health of the individuals.Strength is the ability to overcome resistance or to act against contractions. It is in fact, a product of voluntary muscle contractions caused by the neuro-muscular co-ordination. Strength is the capacity of muscles to exert force against resistance, (Kirkley, 1978). Flexibility is the range of motion available in a joint (Charles B. Corbin and Ruth Lindsey, 1978). Muscular endurance is defined as the ability to muscle to apply force repeatedly into sustains a contraction for a period of time, (Hockey, 1973). The purpose of this study was to investigate the effect of weight training program on the selected fitness variables among the males from pre to post test. A group of 30 subjects were selected for this study from the various sections of physical education college course. The age of the participants was between 18-22 years. The selected physical fitness test considered for this study was body composition (body mass index, BMI), muscular endurance (free squats and push-ups test for 30 sec respectively), muscular strength (Squat and bench press 1RM),The Weight training programme was employed for five weeks in the summer semester, 45 minutes of training per session, four days in a week. A pre and post selected fitness test were conducted before and after the training programme. For analyzing the data, mean, Standard deviation, and t-tests were computed by means of Statistica Software. The analysis of data shows that the body mass index of the participants from pre to post test shows insignificant performance. With regard to other selected variables i.e. free squats, push-ups, squats (1RM), bench press (1RM) shows encouraging and significant results from pre to post test. It is concluded that the effect of five weeks weight training program had not shown any effective means in reduction of the body weight of the participants from pre to post test. Further more the effect of five weeks weight training program had shows improved performance with regard to free squats, push-ups, squats and bench press, which is very encouraging and significant
