The wall sit exercise is a simple yet effective lower-body workout. To perform it, start by finding a clear wall space. Stand with your back against the wall and then take a step or two forward, roughly about two feet. As you stand against the wall, slowly slide down until your knees are at a 90-degree angle, mimicking the position of sitting in an invisible chair. It's important to maintain proper alignment, so ensure your back remains flat against the wall, and your knees are directly above your ankles, avoiding any forward movement. Hold this position for as long as you can, aiming for at least 30 seconds initially, and then gradually increase the duration as your strength improves. This exercise effectively engages your quadriceps, hamstrings, and glutes, making it an excellent addition to your lower body workout routine.
