Isotonicalle because the lenght of the muscles change, while the tension (weights)remains the same.
Weight lifting is the process of contracting your muscles with applied pressure. With enough pressure being pushed muscles will eventually grow.

Because your muscles are contracting and blood is filling the muscles being worked ( thats why your veins bulge when lifting)
1. We can isometrically contract any skeletal muscle of our body. We can contract just one skeletal muscle of the body without contracting any other.However, we should be masters of Original Meditation to be able to put the small muscles of the head into pure isometric contraction. These are muscles of face, muscles within the oral cavity, muscles in front of the neck, those around eye ball and those in the middle ear.2. We can Isometrically contract and relax all the skeletal muscles of the body as a single unit.
Yes, lifting weights involves the conversion of chemical energy (from food) into mechanical energy (used to move the weights). The muscles contracting to lift the weights produce mechanical energy.
Muscles contract either isometrically or isotonically, and the bones provide attachment points for the muscles, one is the anchor point, the origin, and the other is the movable point, the insertion. The joint is where the two bones articulate with cartilage to produce the joint that is the lever.
Primary muscle groups would be your pectorals. Others include shoulders and triceps. If you're doing it correctly, you're also isometrically contracting muscles such as those in your neck, your traps, and many in your lower body to stabilize.
1. The coolness:On each side of our nose, extending from a point above our incisor teeth to the bridge of our nose is a muscle called Compressor naris. Isometric contraction (hardening) of this muscle gives as a feeling of coolness.It should be noted that this muscle is exercised in Yogic exercise called Pranayama .2. The feeling of shivering:Extending downwards from our Adam's apple is a pair muscles called Sternothyroid. This is the muscle we use for singing. If a part of this muscle is contracted isometrically waves of isometric contraction pass to the extremities during breathing.3. The chilly sensation:If these two muscles contract together isometrically during breathing they give us a chilly sensation.If these two muscles contract isotonically (shorten) also it leads to shivering.
Lifting weights = subject builds muscles = predicate
Kegels
Muscles relaxing and contracting.
By contracting muscles in their body.
