History and Evolution of Classic Physique and Open Bodybuilding

The concept of bodybuilding has been around for centuries, with ancient civilizations such as the Greeks and Romans admiring and cultivating the human physique. However, modern bodybuilding as we know it today began to take shape in the late 19th and early 20th centuries. The first official bodybuilding competition, the Mr. Universe contest, was held in 1948, and it was won by Steve Reeves, a legendary bodybuilder who would go on to become a symbol of the sport. Over the years, bodybuilding has evolved and branched out into various categories, including Classic Physique and Open Bodybuilding.
Classic Physique, introduced in 2016, was designed to provide a platform for competitors who wanted to showcase a more balanced and symmetrical physique, with a focus on aesthetics and proportion. This category was created in response to the growing trend of competitors prioritizing muscle mass over overall physique, resulting in a less balanced and less aesthetically pleasing appearance. Classic Physique competitors are required to have a more relaxed and natural posing style, which allows them to showcase their physique in a more subtle and elegant manner.
Open Bodybuilding: A Focus on Muscle Mass and Size
Open Bodybuilding, on the other hand, has been the traditional and most popular category in bodybuilding for decades. This category prioritizes overall muscle mass and size, with an emphasis on muscular development and conditioning. Open Bodybuilding competitors are required to have a more intense and muscular posing style, which allows them to showcase their muscle mass and definition. The posing style in Open Bodybuilding is more dramatic and attention-grabbing, with competitors using a range of poses to highlight their muscular development.
Category | Physique Requirements | Pose Style | Body Fat Percentage |
---|---|---|---|
Classic Physique | Balanced and symmetrical | Relaxed and natural | 6-8% |
Open Bodybuilding | Muscular and massive | Intense and dramatic | 4-6% |

Judging Criteria and Requirements

The judging criteria for Classic Physique and Open Bodybuilding differ significantly. In Classic Physique, the judges place greater emphasis on overall physique and presentation, taking into account factors such as symmetry, proportion, and aesthetics. The posing style, facial expression, and overall stage presence are also critical components of the judging criteria. In contrast, Open Bodybuilding judges focus primarily on muscular development and size, with an emphasis on muscle mass, definition, and conditioning.
In terms of requirements, Classic Physique competitors typically have a lower body fat percentage than Open Bodybuilding competitors, with an average of 6-8% body fat compared to 4-6%. This is because Classic Physique competitors need to maintain a more balanced and symmetrical physique, which requires a lower body fat percentage. Open Bodybuilding competitors, on the other hand, prioritize muscle mass and size, which often requires a lower body fat percentage to achieve the desired level of definition and conditioning.
Training and Nutrition Strategies
The training and nutrition strategies for Classic Physique and Open Bodybuilding competitors also differ. Classic Physique competitors typically focus on a more balanced training program that emphasizes overall physique development, with a mix of compound exercises such as squats, deadlifts, and bench press, as well as isolation exercises such as bicep curls and tricep extensions. They also prioritize nutrition strategies that promote overall health and wellness, such as eating a balanced diet that includes plenty of protein, complex carbohydrates, and healthy fats.
Open Bodybuilding competitors, on the other hand, often prioritize a more intense and specialized training program that focuses on building muscle mass and size. This may involve using heavier weights, higher volume, and more frequent training sessions. They also often use more advanced nutrition strategies, such as carbohydrate loading and protein shakes, to support their muscle growth and recovery.
