Want a strong core? Skip the 3- minute plank


Recently, I walked by a packed evening kettlebell class, a room full of participants doing a terrific plank variation—slowly sliding a heavy weight in front of them from left to right, and vice versa. A plank is one of the gold standards for working the core in which you assume and hold a position. Sit-ups and crunches are no longer the norm for a great set of abs. Traditional core training sought to isolate a single area, such as the six-pack, which is problematic.

All movement originates through the core. The core is an integral part of the protective mechanism that relieves the spine of harmful forces during activities. Deep stabilizing muscles allow a protective mechanism for posture control and athletic performance.

The main reason sit-ups don’t help you is that they can damage the spine. The traditional sit-up, writes Dr. Stuart McGill in “Ultimate Back Fitness and Performance,” imposes about 730 pounds of compression on the spine. Those participants in the evening workout were shown ways to retire old concepts and learn from a great coach, in her presentation of fresher research: plank variations.

Secondly, planks recruit a balance of muscle from the front, sides and back of the body, as the core goes far beyond a six-pack. Even though Cher boasts about holding a three-minute plank, you don’t need to hold a plank that long. There are better ways to get strong. Once you can perform a 20-, 30- or 60-second plank, you can advance from a stability level to light loads and additional stimulus in a plank.

Here are two simple stability tests to determine your core strength before you add additional stimulus, as in that kettlebell class.

Forearm plank, 20 seconds

  • Lie on the floor, with the feet flexed, toes towards the shins, and the elbows and forearms under the chest area. To begin, lift the body off the floor in a position in which the arms are perpendicular to the floor, and the elbows directly under your shoulders, hands under your face.
  • Brace the core, lock the knees and tighten the glutes.
  • Have a friend or partner place a long stick or broomstick in line with your spine.
  • Start the clock only when you are in straight body alignment.
  • Hold for 20 seconds.

Fail is any part of the body sagging away from the stick.

Pass is if your torso remains in full contact with the stick for 20 seconds without any noticeable quivering.

  • In a kneeling position with hands on the floor, have a friend or partner place a stick or broomstick in line with your spine.
  • To begin, raise the right arm up and extend it parallel to the floor.
  • Simultaneously raise the left leg up and extend it backward, also parallel to the floor.
  • Touch both the arm and foot back under the body to touch left elbow to right knee.
  • Return to the fully extended position for six repetitions. Repeat on the other side.

Fail is if at any point during the test, the body sags away from the stick, or it rolls off the back.

Pass is if you the body is in contact with the stick, and control is maintained throughout the test.

Fix your back pain; don’t forget your glutes

Through proper exercise, movement, and posture, you can help low back pain.

Kevin Mullins, a master instructor for Equinox Sports Club in Washington, D.C. understands low-level chronic back pain and found three recurring issues that personal trainers can address with their clients. Excess bodyweight, sedentary lifestyles, and improper exercise selection, are areas a trainer can help a client with, all factors having a correlation to low back pain. It is estimated that over 84 % of the population will experience an episode of LBP, from children to the elderly, at some time during life.

As well, age, stress, occupational factors, lack of flexibility or hyper-mobility, sports, postural habits, and smoking are other contributing factors.

Recovering from low back pain is a long complex road. If you are in pain, but not dealing with any diagnosed or diagnosed medical issue, you fall into the category of mechanical low back pain, or LBP.

Unlike a car, says Dr. McGill, one of the most widely respected spine researchers in the world, where you change one thing and it’s fixed, fixing a back is different. Back pain is more complicated and is much more than just fixing one part. Because, McGill notes, it comes down to cold hard science.

How the  spine functions and it’s relationship the rest of the body is the key to being free of back pain. Through proper exercise, movement, and posture, even disc bulges can be made less painful, and usually pain-free, he notes. 

Of course it’s hard to stick to a program if you are in pain. You lose the very conditioning that could help treat LBP, or even more frustrating, gain unwanted weight.That extra weight is the number one reason clients turn to a trainer, with or without low back pain. Healing starts to occur when you keep the bigger picture in mind; a good diet,adequate sleep, and a matched activity/ training program.

Tip #1 The Big Picture 

A traditional strength training can improve strength and muscle mass. Overall body strength as well as a daily walking regime are important part of a client’s program to become free of back pain.

Tip #2  Bend at the hips, rather than the spine 

There is a direct correlation between posture and pain. You can reduce episodes of back pain by reminding yourself to bend at the hips, which is a ball and socket joint, not the back. The spine does bend, but repeated spine bending, whether it’s picking up a weight in the gym, or swinging a kettlebell, could eventually lead to delaminations in the layers of the discs. Someone swinging a kettlebell, along with their back, instead of stabilizing the spine while doing so, to protect the spine, risks further trauma to an already sensitive back. When you’re performing squats, for example, sink your hips back towards your heels, like sitting onto a low park bench. Keep your eyes forward. Use your hips rather than round your back.

Tip #3  Rethink the core 

To enhance back fitness, you need a strong focus on core strength, as theses muscles play a protective role. The internal and external obliques, transverse and rectus abdominals, and the erector spinae are arranged around the spine and act as guy wires to allow the spine to control movement, bear loads  and facilitate breathing. But all too often you see good athletes and gym members entirely focused on just the rectus abdominis, commonly known as the “6 pack”. If we go back to our car analogy, focusing on only one part won’t solve back pain.

The core musculature extends to the entire body,  from the upper back down to the pelvis, not just the 6 pack.The lats, trapezius, the gluteals, hamstrings, hip flexors and inner and outer thighs all have an impact on the spine. 

Typically what happens with someone experiencing low back pain, is that that pain hasn’t allowed them to adequately train. The outcome is weaker core and gluteal muscles. This is where science comes in.

To see how important the glutes are for strength, try this exercise; Stand on one leg and balance. Then sink your hips back slightly, behind your heel, and see how much more stable standing on one leg feels. This is a great demonstration of the role the gluteals play regarding core strength.

Your progression, with an awareness on good movement patterns, including planks, back rows, squats and bridges, for example, should be aimed at strengthening more and more of your whole body, back to health.
