The pressure on their bone, center of mass and balance , the amount of energy they burn.
Weightlifters are actually working out. Lifting the weights up and then lowering them does put a strain on their muscles, which will make them stronger.
The difference between actual quantity and standard quantity is called the material quantity variance.
A quantity is how much of somethere is, and a estimate is a complete or educated guess. If you know the actual quantity, then it isn't a guess. So i guess the difference is one is a guess and one is not.

Accuracy
Accuracy is the level of closeness between a measured quantity and the actual or standard value. It indicates how well a measurement represents the true value of the quantity being measured.
The actual amount of an object refers to its physical quantity or volume that can be measured accurately using standard units like grams, liters, or meters. It is the precise or exact measurement of the object's size, weight, or capacity.

The duration that weightlifters hold the bar up can vary significantly depending on the lift and the training goals. In competitive lifts like the snatch or clean and jerk, the bar is typically held for just a few seconds during the actual lift. During training, weightlifters may hold the bar in specific positions (like a pause at the top or bottom) for longer to build strength and stability, usually ranging from 1 to 5 seconds. Overall, the hold time is generally short and focused on maximizing power and technique.
The equilibrium quantity supplied is lower than the actual quantity supplied. The market price is below the equilibrium price.
