The potential energy increases because of the weightlifter lifting it above his head (Hope this helps)XP
The type of energy present in a barbell being lifted or a shot-put being thrown is primarily mechanical energy. Mechanical energy is the sum of an object's potential and kinetic energy due to its position or motion.

When an object is lifted 6 feet off the ground, its potential energy is a certain value based on its height and mass. If the same object is then lifted 12 feet off the ground, its potential energy will be doubled compared to when it was lifted 6 feet. This is because potential energy is directly proportional to the height to which the object is lifted.
The potential energy of an object is directly proportional to its height above the ground. So, if the object's potential energy increases by a certain amount when lifted 10m, it will increase by twice that amount when lifted 20m.
If the car is lifted twice as high, its potential energy would be four times as much. Potential energy is directly proportional to the height to which an object is lifted, so doubling the height would result in a quadrupling of potential energy.

kinetic energy being enacted. this energy is giving rise to potential energy too, as the item is being lifted into the air. When an item is lifted, it is given potential energy, as this potential energy is what fuels its future descent. So, when moved, kinetic energy is both moving the object, and storing potential energy for future use.

The barbell with potential energy was raised to a certain height, which gave it gravitational potential energy due to its position relative to the ground. The other barbell did not have potential energy because it was resting on the ground and its position did not allow for any stored energy.
The power during the lift is (weight of the barbell in Newtons)/4.4 watts.Note:Power is not "expended". Energy is. Power is the rate at which energy is expended.

The work done in lifting the barbell is given by the formula: Work = force x distance = 500 N x 2.2 m = 1100 J. The potential energy of the barbell at this height is equal to the work done, so it would also be 1100 J.
