The reason 45 lb plates are standard in the United States instead of 50 lb plates is rooted in historical and practical factors. The use of 45 lb plates originated from the international standard for Olympic weightlifting, where the 20 kg (44.1 lbs) plate was used in various countries. The 45 lb plates are a close approximation of this 20 kg standard, and their adoption in the U.S. aligns with the need for uniformity in training and competition.
In addition to historical standards, the use of 45 lb plates in the U.S. is also due to the country’s reliance on the imperial measurement system, which uses pounds and ounces instead of kilograms. The 45 lb weight is convenient because it’s a whole number close to the 20 kg standard used in other countries. This allows for easier conversion between weight measurements, particularly for athletes who travel internationally for competitions.
Finally, the 45 lb plate size ensures consistency across various lifting activities and helps in training for a wide range of lifters, from beginners to advanced athletes. Its design also allows for a standard 45 lb barbell setup that can be used across different types of training programs.
The number of 45 lb plates that fit on a barbell depends on the type of barbell and the specific training requirements. A standard Olympic barbell typically has a 2-inch sleeve diameter, which can accommodate a wide variety of plates. On a standard 7-foot Olympic barbell, which weighs 45 lbs itself, you can fit a pair of 45 lb plates (one on each side) without causing the bar to exceed its weight limit.
If you’re looking to load more weight, it’s possible to add additional 45 lb plates. For example, if you’re lifting heavy for powerlifting or performing high-intensity workouts, you can stack multiple 45 lb plates on each side of the barbell. Depending on the barbell’s total weight capacity, you could fit up to 8 45 lb plates (four per side), totaling 360 lbs in addition to the weight of the barbell itself. However, keep in mind that the more plates you add, the more care must be taken to ensure proper balance and form during lifts to prevent injury.
The thickness of 45 lb plates can vary slightly depending on the material and brand, but typically, 45 lb iron plates have a thickness of about 1.25 inches (3.2 cm). This thickness is designed to provide a balance between weight distribution, durability, and ease of use during exercises. The 45 lb plates are thick enough to hold a significant amount of weight while maintaining a compact and manageable size that allows for easy loading and unloading from the barbell.
For plates made from other materials, such as rubber or urethane-coated 45 lb plates, the thickness may vary slightly due to the added coating. Rubber and urethane coatings are designed to reduce bounce and protect both the plate and the floor from damage, but they may make the plates slightly thicker than their bare metal counterparts.
The thickness of the 45 lb plates is also an important factor when stacking plates on the barbell, as it affects the total load capacity. Thicker plates provide a more stable fit on the bar and help ensure proper balance, which is essential for maintaining safety and optimal performance during weightlifting exercises.
