Abs or abdominals (ab – dom – uh – nl) The abdominal muscles are a group of 6 muscles that extend from various places on the ribs to various places on the pelvis. They provide movement and support to the trunk, often called the core. They also assist in the breathing process.

Adductor muscle (uh – duhk – ter) A muscle which brings a part of the anatomy closer to the median plane of the body.

Aerobic (ai – roh – bik) Requiring the presence of air or oxygen.

Bis or biceps (bahy – seps) A flexor muscle located in the front of the upper arm and assisting in bending the arm.

Core (kohr) – see abdominals – The six abdominal muscles are: transverse abdominal, two internal obliques, two external obliques and the rectus abdominis.

Cuffs or Rotators Cuffs (roh – ta – tor) A bandlike structure encircling and supporting the shoulder joint, formed by four muscles attached and merging with the joint capsule.

Glutes or gluteous maximus (gloo – te – us mak – suh – muhs) The broad, thick, outermost muscle of the buttocks, involved in the rotation and extension of the thigh. The largest muscle in the body.

Obliques (oh – bleek) The external oblique muscles of the abdomen functions to pull the chest downwards and compress the abdominal cavity.

Its contraction also rotates and side-bends the trunk by pulling the rib cage and midline towards the hip and lower back.
