No, not all weight plates are 45 lbs. In fact, weight plates come in a variety of sizes and weights, allowing gym-goers to choose the appropriate weight for their specific training goals. The 45-pound plate (approximately 20.4 kg) is one of the most common weights used in gyms, particularly in the U.S., and is standard for Olympic weightlifting bars. However, other plate sizes such as 25 lbs, 10 lbs, 5 lbs, and 2.5 lbs are commonly used in strength training routines. The 45 lb plate is typically used for heavier lifts, while smaller plates are used for lighter exercises or to adjust the total weight on the bar incrementally. Furthermore, weight plates can come in different types, such as bumper plates, which are often made of rubber and are used in Olympic weightlifting. The choice of plate depends on the individual’s strength level, the type of lift being performed, and whether the lifter is working on adding small or large increments of weight.
When lifting a barbell with 45-pound plates, you need to account for the total weight on both sides of the bar. If you load a 45-pound plate on each side of the barbell, the total weight on the bar becomes 90 lbs (45 lbs x 2 plates). In addition to the plates, you also need to consider the weight of the bar itself, which typically weighs 45 lbs for standard Olympic bars. Therefore, the total weight of the setup with two 45-pound plates on an Olympic bar would be 180 lbs (45 lbs for the bar + 45 lbs on each side). It’s important to note that not all bars weigh the same. For example, standard bars may weigh 35 lbs, and specialty bars may weigh more or less than the standard Olympic bar. When calculating the total weight being lifted, always account for both the plates and the barbell.
Yes, 100-pound plates do exist, although they are not as commonly used as standard plates like 45 lbs or 25 lbs. These larger plates are typically used in gyms that cater to heavy lifters or specific strength training exercises that require high weight increments. 100-pound plates are often seen in commercial gyms or specialty powerlifting gyms where lifters are looking to add large amounts of weight without constantly changing plates. These plates are often used for exercises like the leg press, squat, or deadlift, where the larger load allows for efficient progression in heavy lifting. However, due to their size and weight, 100-pound plates can be difficult to handle, especially for smaller lifters, and are not typically used for exercises requiring precise incremental weight adjustments. Additionally, 100-pound plates are less common in gyms due to their cost, space requirements, and handling difficulties. Many lifters opt to use multiple 45-pound plates or 50-pound plates instead for practical reasons.
