General Background: Bodybuilding development depends on structured resistance exercise and appropriate nutritional intake tailored to athletes’ physical characteristics and training experience. Specific Background: Nutritional supplements are widely incorporated into bodybuilding programs, but their use must correspond with body weight, physical capacity, and training age to support targeted muscular development. Knowledge Gap: Comparative evidence remains limited regarding muscular development produced by selected exercises combined with whey protein or amino acid supplementation among young bodybuilders. Aims: This study develops a selected exercise program incorporating two supplements and compares muscular development between two experimental groups. Results: An experimental equivalent-group pretest–post-test design was applied to 20 randomly selected male bodybuilders aged 18–21 years from a population of 60 athletes in Najaf Governorate. Participants completed 30 sessions over five training days per week. One group received whey protein, whereas the other received amino acids, with quantities adjusted to athletes’ characteristics and administered around training sessions. Both groups demonstrated post-test development in assessed body regions. The amino acid group recorded significant pretest–post-test differences in the pectoralis major, lateral deltoid, and biceps brachii. Comparative post-test findings indicated superior values for the group receiving whey protein across the targeted regions, including the chest, shoulder, arm, oblique, and abdominal areas. Novelty: The study combines a structured exercise schedule with a direct comparison of two supplement protocols using judge-rated muscular coordination. Implications: Supplement programs should be designed according to individual needs and implemented under qualified professional supervision to reduce inappropriate use and support balanced muscular development.

Highlights:

• Both experimental groups improved after thirty structured training sessions.
• The first supplement group achieved superior post-test scores across targeted body regions.
• Dosages should correspond with athletes’ weight, capacity, and training experience.
