is the plank bad for your lower back
Benefits of Side Plank Exercises. Side plank exercises target the gluteal muscles, obliques, quadriceps, hamstrings, thigh abductors and adductors. Strengthening these muscles means that your lower back and spine have more support and are better protected from injury caused by back strain and/or sudden movements. Side plank exercises also improve core strength; this means increased core stability, which translates into a stronger back and minimal soreness.
