Agree with Crab.
Wearing a lifting belt can provide several benefits when lifting weights, but it does not directly increase strength. The primary function of a lifting belt is to provide support and stability to the lower back and core muscles during heavy lifting exercises - this support can help to reduce the risk of injury and allow the lifter to maintain proper form throughout the lift, which can ultimately lead to more effective training and improved performance over time. Additionally, wearing a belt can increase intra-abdominal pressure, to help one to stabilize the spine, to help with the transfer of force from the legs and hips to the barbell which in turn will help the X person to have a better form with less effort from their part.
The longer the distance, the less weight you lift. So, technically speaking, the moment you put the most force into something is when you can't move it.
This statement is not entirely accurate. The amount of weight you can lift depends on several factors, such as your physical strength, technique, and the specific muscle groups involved in the lifting process. The distance you move the weight is also a factor, but it does not necessarily mean that you lift less weight as the distance increases. When you lift a weight, you apply force to it, which can be measured in Newtons - the force you apply depends on the weight of the object and the acceleration you give it where force equals mass times acceleration. This means that if you want to lift a heavier weight, you need to apply more force to overcome the object's inertia and accelerate it. In terms of distance, the force you apply may vary depending on the lift's specific mechanics. For example, in a deadlift, the weight is lifted from the ground to a fully upright position, which may involve a longer movement distance. However, the lifter will apply maximal force at the start of the lift to break the weight's inertia, and then gradually decrease the force as they approach the upright position. Basically, the amount of weight you can lift depends on multiple factors, including force, acceleration, and the specific way of the lift (like Crab said the Sumo technique for lifting which can be a bit of cheating but its still doable as some people have problems with the back or legs and this position will be beneficial). The distance you move the weight is a factor, but it does not necessarily mean you lift less weight as the distance increases.
Some individuals may be able to lift more weight using the conventional deadlift technique, while others may find greater success with the sumo deadlift technique. In some cases, the opposite can also be true. Personally, I find that I am able to lift more weight with the sumo deadlift technique, but my legs become fatigued more quickly than when I use the conventional method. While the conventional deadlift places greater emphasis on the lower back, the mechanics of lifting play a significant role in determining which technique is most effective for an individual. For instance, lifting heavy objects with poor form can be more challenging than with good form, and adopting good form may result in increased strength. Ex: Someone who can lift 100kg while leaning forward in an awkward position, but can suddenly lift 130 kg with good form. Would this count as a significant improvement in strength (a stat amp...funny thought)? Similarly, someone using a lifting belt to stabilize their spine may be able to lift 140 kg with good form. In this situation, it is likely that the individual could have lifted 140 kg from the beginning, but their inability to stabilize their spine and lower back due to poor form prevented them from performing at their maximum capacity.
