This refers to your core: the three layers of muscle in your midsection -- from the abdominal and back muscles to the muscles around the pelvis. The powerhouse is the most important muscle group to work because it's the foundation for all movement. Engaging your core is more than working your abs: Your core stabilizes your body because it uses all your midsection muscles. Here are three steps to make sure you're engaging your powerhouse the next time your instructor tells you to "activate" it: 1. Squeeze and tighten your pelvic floor muscle. 2. Pull your navel in toward your spine. 3. Lift your abs up and along your spine toward your ribcage.

Most of us have at least one set: To find them, place your palms on your lower back and inhale deeply. Do you notice a subtle movement through your muscles? This is the area into which floating ribs extend. Floaters are important to protect and maintain a healthy low back, lungs, liver, colon and kidneys, says Francine Tseng, an osteopathic therapist. A few reasons an instructor may use the term "floating rib" is to help draw awareness to your lower ribcage, optimize breathing or encourage you to recognize that region softening naturally as you straighten your spine.

Pronounced "so-az," this is the thick muscle deep behind your abs that runs through your hips to connect your lower back to your upper thigh. It's at the very center of your core and is your strongest hip flexor muscle. Have a hard time firing up your glutes when you do squats? If so, it's likely you've got a tight psoas. It plays a key role in proper posture, moving your hip joints and spine stabilization and acts as a shelf for major organs. If the psoas is too tight, it can cause overarching in your lumbar spine, unbalanced movements and pain in your lower back and pelvis. An instructor may refer to the psoas to increase your awareness of your core, hip flexors and body alignment to help prevent injury and stiffness.

This refers to the natural position of the spine. Many instructors encourage their students to be aware of maintaining a neutral spine to protect it. Being constantly aware of the spine's natural alignment is crucial to prevent strain, maintain balance, increase energy, activate the right muscles and improve breathing and circulation of bodily fluids. Not only will your instructor direct you to "come to a neutral spine," but they may also talk about the three natural curves to help with proper alignment: cervical spine (neck area), thoracic spine (middle of the back) and lumbar spine (lower back).

这个三角形肌肉开始ong the back of your neck and shoulders, then connects with the spine down to your mid-back region; also known as your "traps." This muscle plays a key role in developing upper-body strength. You use it to move, rotate and stabilize your shoulder blades. You have two symmetrical trapezius muscles: one on the right and left of your the spine. Instructors may target the upper, middle and lower muscles of your midsection when they have you work this area. Building strong traps increases your upper-body strength and helps sculpt your upper torso symmetrically.
