Core Strength

How’s your core? Have you been neglecting the most important part of your musculature?  Abdominal muscles are the center region of your body for a reason.  They are the alpha of all movement and support your frame during running and many workouts. Abdominal muscles are known as the powerhouse because it controls other muscle groups in the hip, back, upper and lower body. The four abdominal groups work as a whole and consist of:

  1. External oblique
  2. Internal oblique
  3. Rectus abdominal, and
  4. Traversus addominus

These four muscles act to stabilize a runner’s posture during running, control lower extremity motion, enhance performance (stride length, speed, and power) and prevent running-related injuries.  Weak abdominal muscles can negatively affect lower extremity biomechanics by causing several running-related injuries such as bursitis, lower back pain, stress fractures, tendinitis and more. The abdominals aid other muscle groups to coordinate movement efficiently.  Especially on grueling long runs, abdominal muscles hold you upright, helping you maintain proper posture on flat, hilly, and trail runs. Essentially, a strong core helps you become a more efficient runner.

Unfortunately, many runners neglect strength training, concentrating mainly on running and strengthening the lower extremities. This can causes instability, and imbalance in the musculature, thus leading to injuries.

So why aren’t you strengthening your core? It only takes 15 minutes three or four times a week, even less if your session is rigorous.

So Which Abdominal Exercises?

There are many ways to strengthen your core, through basic crunches or Pilates and yoga. Personally, I prefer Pilates and yoga because the poses are more efficient and don’t require hundreds of reps to feel the effect. Also, crunches only isolated one muscle, whereas Pilates and yoga exercises, such as the Plank, focus on training the core as an integrated stabilizing system. Planks work several muscle groups at once, such as the arms, abs, back, chest, shoulders, quads, and hamstrings. Several variations of the plank also effectively strengthen the arms and wrists along with the spine and abdomen. Planks target all core muscles, whereas basic crunches only target one muscle at a time, with the need to perform several specific exercises to hit all four core muscles (external and internal oblique, rectus abdominal, and traverse addominus).

Several Basic Versions of the Plank Pose
