The mechanical advantage changes. The proportion of needed effort in relation to the rock's weight changes.
Lifting a dumbbell is a isotonic contractins because the tension remains unchanged and the muscle's length changes. Any lifting of objects is considered an isotonic contraction.
it helps with lifting or moving a load.
no
A fixed pulley does not make the force applied easier, it changes the direction of this force. For example, instead of bending over and lifting and object, a fixed pulley lets you lift it by pulling down on a rope.
The most common types of back pain injuries are usually improper lifting techniques and car accidents. You can avoid lifting injuries by always lifting with your legs instead of your back or upper body.
Hold your arm straight out to the side parallel to the ground. Rotate it so that the palm of your hand faces upward. Make a fist. Pretend that you are lifting a heavy weight and bring your forearm perpendicular to the ground.
Concentrate on a steady base and drive through the ball after contact instead of falling back.
to avoid injuries and body pains
Yes, and a wider grip can help target the chest more, instead of the triceps.
Anything you want to do..but if you mean for exercise then you could always do sports. You can run or swim or ride a bike. Lifting weights is about the only way you are going to get bigger though (i mean muscle mass, not skeletal size)

"Are lifting" is a verb. It's the present progressive tense of lifting. "You" is a pronoun.
The mechanical advantage changes. The proportion of needed effort in relation to the rock's weight changes.
Lifting weights
Well, I hate to tell you this, but the way to pitch faster is practicing the proper mechanics, weight lifting (strengthing the forearm, bicep, and tricep), you also have to build up the shoulder joint to aviod injury. (; But it will all pay off if you want to go far in the softball world
