This study aims at investigating the effect of using complex training in developing in developing the snatching skill of weightlifting players, the experimental approach with the experimental design was used on one experimental group with the (pre-post) measurement method. The Research sample was selected intentionally, represented by (12) youths at the Muslim Youth Club in Zagazig (Sharqia Governorate) for the year 2022, The proposed training program was applied using complex training for ten (10) training weeks with three (3) training units per week, The physical variables under study (Maximum fixed force - kinetic force - force characteristic of speed - flexibility - balance - agility) and the skill variable is the skill of snatching. Statistical treatment included (mathematical mean, standard deviation, correlation coefficient, T-test). Study Results showed statistically significant differences at the level of 0.05 between (pre-post) tests favoring post-tests in both physical and skillful tests - under study - attributed by the researcher to using complex training within the proposed training program. The researcher recommends the need to use compound training in weight lifting training programs.
