The following exercises are far superior, they ensure significant spinal stability, spare the spine of many injury mechanisms and and are designed to to build muscular endurance.
5 Core exercises that don't flex your spine:
1. Front Planks – On your forearms and toes, establish a straight line from head to toe. Soften your knees, keep a neutral spine and breath down into your belly button. Hold 10-30 seconds.
To increase the difficulty, add in a stability ball and "stir the pot" with your elbows.
2. Side planks – On one arm, stack your feet and hips, extend both legs straight and align your body in a straight line from head to toe. Keep your chest open and shoulders away from your ears. You may stagger your feet for balance, as in the picture.
You can modify this by dropping down to one knee.
3. Table top – On all fours, knees under hips, wrists under shoulders, neutral spine. Alternate lifting your opposite arm and leg while maintaining square hips and a stable pelvis. Place a water bottle on your low back as you extend your opposite arm and leg, the water bottle should not fall off, if it is you are not keeping your hips level.
4. Knee tucks – Start in the plank position from your hands, engage the core and pull your knees into your chest. You can use a variety of objects to make this exercise challenging.
Knee tucks on the stability ball:
5. Back extensions – lie prone on the floor with your arms above your head. Engage your core, and lift your chest, shoulders and arms up off the floor. At the same time squeeze your glutes and lift your quads up off the floor, creating a U shape.
You can simplify this exercise by lifting just one arm and one leg at a time.
Until next time, keep fit and have fun….
