Yes.
Skeletal muscles will have a flexor and an extensor.
The flexor bends the joint.
The extensor straightens it out again.
you find muscle pairs in your legs... like you hamstrings or quadriceps.
Most muscles work in pairs, known as antagonistic pairs, where one muscle contracts while the other relaxes. However, some muscles, like the diaphragm, function independently to facilitate breathing without a direct opposing muscle. Additionally, certain muscles in the eye, such as the lateral and medial rectus, can also work in a more coordinated manner rather than strictly in pairs. Overall, while the majority of skeletal muscles operate in pairs, there are exceptions based on their specific functions.

skeletal muscles
Because muscle cells can only contract, not extend, skeletal muscles most work in pairs. While one muscle contracts, the other muscle in the pair relaxes to its original length.
The skeletal muscle is the only type of muscle which is voluntary.
muscle fiber
Probably skeletal muscle but smooth muscle would be a close second.
Of the three muscle types (cardiac, smooth, skeletal), skeletal muscle is the most abundant.
There are three basic types of muscle: smooth, skeletal, and cardiac. Smooth muscles are part of organs like the intestines, skeletal muscles are connected to bones, and cardiac muscles makes up most of the heart.
One is the agonist and the other is called the antagonist. Agonist: muscle which is the main mover, it contracts and shortens Antagonist: muscle that lengthens and controls e.g. flexion at the elbow: the biceps are the agonist and the triceps are the antagonist.
Most of the muscles (or mucle groups) that you know are voluntary or skeletal muscles. Biceps, triceps, quadriceps, abdominals, pectoralis, latissimus dorsi, sartorius, etc. are all skeletal muscles, or muscle groups.
