💡Tips
The clean and jerk is a weightlifting movement that require strength, timing, and nerve. To perform a clean and jerk movement, a person must pull a heavy bar from the floors and catch the bar in a front squat and then stand up and drive the bar overhead. If a person misses any part of the movement, the movement will fails.
Because the movement is so complex, a strong weightlifter requires a strong sense of how much weight a person can lift and how to train around that lift. A clean and jerk calculator allow a person to answer these questions. By entering the weight lifted and the number of repetition performed into the calculator and entering other context for the calculator, such as body weight or squat numbers into the calculator, the calculator can provide information regarding a one-rep max, a daily target number, and a set of suggestion for the attempts to be made at a meet based on the strategy the lifter chooses.
How to Use a Clean and Jerk Calculator
The calculator also makes comparison between the clean and jerk and other lifts, such as the snatch, pulls, and front squat to allow a person to understand where their weakness lie. These comparison help a person understand their limitation in relation to the lifts they perform. For instance, if a person finds that their front squat is only a few percent more than their clean and jerk, the legs are not a limiting factor.
However, if a person finds that their clean pull is much higher than their clean and jerk number, they may have trouble with the turnover or the jerk aspect of the movement. If the ratio of a persons snatch to their clean and jerk is low, it indicate that the snatch is a limiting movement for that particular lifter. The calculator also take into account a person’s readiness for the movement and fatigue.
A tired body will not be able to perform as well as a rested body in a clean and jerk lift. By entering a readiness and fatigue number into the calculator, the calculator can adjust the opener (the first lift of a competition) to ensure that it is within the ability of the lifter to perform without failing. A small decrease in readiness can shift the calculated plans from an aggressive opening of the lifts to a more conservative plan.
Within the calculator is a strategy for the attempts a lifter will make during a competition based on percentage provided within the calculator. Some people prefer to start off with a conservative weight to allow for a high third attempt. Others prefer to start with a higher number to build to a high second attempt.
The calculator allow for the toggling between these two calculations to show the weights of each plan to allow for the setting of the weights without the need to argue within the warm-up room. Within the calculator are three training zones based on the percentages within the calculations. Each training zone have a purpose within training.
The zone between 60 and 70 percent of a one-rep max allow for high bar speeds and the practice of different position within the squat. Between 75 and 85 percent of a one rep max allow for the building of the power needed for the snatch while still allowing for multiple repetitions. Above 90 percent allow a lifter to focus on single attempt with the goal of improving the snatch numbers for that lift.
Each of these training zones help to prevent a person from dedicating every training day to max out the snatch or the clean and jerk lift. The calculator can also be used by someone returning from injury or time off the lift. By entering a lower readiness and a rebuild purpose for the body, the daily target weight will be much lower than any old max for that lifter to avoid struggle with the movement.
The calculator will not provide medical advice but will remove the math that most weightlifters incorrectly calculate when tired. Body weight and height are required to calculate the relative strength of a person in relation to other lifter within the same weight classes. Additionally, the ratio of the strength of a persons snatch or clean and jerk to body weight can provide insight into how many calorie were expended during the lift to give an overall energy estimate for that lifter.
This information isnt a replacement for a nutrition plan but does help to provide insight into how a lifter may need to adjust the food they consumes. The ratio of snatch to snatch and jerk and the ratio of clean pull to jerk allow a person to understand where their focus should be within their lift. For instance, if snatch numbers are low, a person should focus on improving their snatch lift.
A high ratio of clean pull to jerk indicate that a person should focus on the catch or the jerk portion of the clean and jerk lift. These ratio allow people to understand their areas of strength and weakness. The calculator depend upon the honesty of the numbers entered into the calculation of a persons ability.
Using a high number from a perfect day three months ago will lead to the presentation of an overly optimistic calculation. Using a number from a tired session will yield a more honest number. The difference between these two number could of helped to indicate whether or not the training plan will be successful.
Over time, a person will use the calculator to become accustomed to the information it present. A person will no longer be asking the question of what their maximum weight lifted in the past but rather what their weight should be for the day. The calculator allow for a person to remove the mathematics from the mind and to focus on the training itself.
