The Stapedius, the smallest skeletal muscle in the human body, which is about 1 mm in length, is regarded to be the weakest muscle. It originates from a prominence known as the pyramidal eminence at the posterior edge of the tympanic cavity. It inserts into the stapes' neck.
Glute Muscles
Perhaps the most neglected muscle group in the body, the Glutes are also one of the most important muscle groups for proper biomechanics and optimal sports performance. They're also connected to your spine, so weak Glutes muscles can lead to back pain and injury.
The palmaris longus is a muscle visible as a small tendon located between the flexor carpi radialis and the flexor carpi ulnaris, although it is not always present. It is absent in about 14 percent of the population; this number can vary in African, Asian, and Native American populations, however.
What muscles develop the fastest? Phasic muscles like the pectorals, rhomboid muscles, glutes, and the trapezius muscles.
Late teens and early twenties are the perfect age to start bodybuilding. Puberty and bodybuilding are closely related because this is the fastest time for muscle growth. Between, 17-25, you will experience testosterone driven growth burst in your muscles.

The triceps are a larger muscle group than the biceps, which means they have more potential to grow.
Current research indicates that three primary mechanisms are involved in exercise-related muscle growth: muscle tension, muscle damage, and metabolic stress (Schoenfeld 2010). Muscle tension. Tension exerted on muscles during resistance exercise is generally considered the most important factor in muscle development.
Is Bodybuilding Possible after the 30s? It's not impossible yet become harder to build muscles as you age.

Building strong shoulders can be tricky and if done incorrectly can lead to injury. To safely improve shoulder strength without causing overuse injuries, I recommend a maximum of two upper body training days per week with one to two recovery days in between.
In a (not-so-surprising) study conducted by Western Illinois University, women rated abs as the sexiest muscle on a man's body, ThePostGame.com reports.
The strongest muscle in the body is debatable. Some physiologists believe it's the masseter (used for chewing), while others claim it's the gluteus maximus (buttocks), or the rectus femoris (part of the quadriceps in the thigh). It's not easy to determine partly because muscles don't work alone.
The prevalence of the palmaris longus (PL) muscle varies more than any other muscle in the human body. Its absence across the world ranges between 1.5% and 63.9%.
The glutes and hips are some of the most common weak muscles. Inactivity from sitting is often the culprit.
