The weight training technical variations on the execution of the exercises, such as range of motion, lever arm, may change the muscle pattern activation, which evolve on different muscle activity. The aim of this study was to analyses the muscle of the pectoralis major clavicular head, pectoralis major sternocostal head and anterior head of deltoid muscle on fly exercises, which investigate range of motion in 30, 60, 90 degrees on horizontal plane and the incline plane (30º) in seven healthy subjects. The results did not shown any differences in the pectoralis major clavicularhead in the horizontal and incline (30º) conditions such as the pectoralis major sternocostal head. The anterior deltoid head has shown major activity in incline condition (30º) when compared with horizontal plane conditions. Statistically significant differences have been evidence of the 90 degree compare with 30 degree angle for all muscles analyzed. It was concluded that to get great muscle optimization in fly exercise, great range of motion lead to bigger muscle activity. The incline plane only leads the anterior deltoid to a greater muscle activity.
