The lower body refers to the hips, knees, thighs, legs, ankle joints and feet. Strengthening the muscles in your legs provides a solid base and plays a crucial role in maintaining good balance, stability, and supporting healthy movement patterns in your daily life such as walking, running, climbing stairs, and even standing for extended periods of time. For example, each time you pick an object up from the ground, you perform a deadlift. Every time you sit in your chair, you do a squat. Lower body strength is essential to maintaining these functional movement patterns, increasing your overall health.
