it doesn't, my uncles a physiotherapist and he says its just a stereotype!
Yes, lifting a pencil requires using muscles, which is considered physical work. However, in the context of physical activity or exercise, lifting a pencil would not be considered a significant form of exercise.
Lifting a box involves exerting force to overcome gravity and move the box vertically. Work is defined as force applied over a distance, so lifting a box requires work to be done against the force of gravity as the box is raised. Thus, lifting a box involves transferring energy to the box to move it to a higher position.
Lifting a 50 kg sack a vertical distance of 2 m requires more work, as work is calculated as force multiplied by distance. In this case, the weight of the sack (force) is higher, resulting in more work done compared to lifting a 25 kg sack a vertical distance of 4 m.
it reduces the work by making an object easier to carry or lift to a higher or lower ground
Sliding usually requires less work than lifting. Lifting involves using more muscle strength and expending energy, while sliding takes advantage of gravity and requires less physical effort.
Contrary to popular belief, lifting weights while you are still growing does not stunt growth. It was believed that breaking a bone could damage the ends of the bones that are still growing, but this is not the case. Strength training has only benefits, if done correctly, whether you are young or old.
No. It is a myth.
Lifting 40 pounds at the age of 13 can affect your growth. It can cause a persons muscles to become weakened later on. The age of 13 is too young to be lifting heavy weights.
No way!
People do not stop growing by lifting weights. It was believed that weight lifting damaged the growth plates and stunted growth. It CAN happen, but only with very heavy weights, such as sets of 3-5 reps. They say no one should do HEAVY weights until they are 18, or fully grown.
The pulley makes work of lifting easier then lifting by hand.

no
Yes in a way it can, you see if you work out properly there is none or little height benefits but do it improperly can affect bones and plates and muscles vital to growing
