As endurance athletes, the focus often lies on volume in training i.e more time for running, swimming or whichever sport we are focusing on. the core is a often forgotten (or maybe skipped) part of the training.
Having a strong core is vital for a functioning body, especially as an endurance athlete. And with that said, let’s not forget about having a balance between the front and back muscles of the core, i.e between the abdominal and back muscles.
Your core strength is a combination of your abdominal muscles and your back muscles, and it is used all the time. A strong torso will give you good posture, which is beneficial for the expansion of your chest, which in turn has a positive effect on your breathing and oxygen uptake.
As endurance athletes, you should train core-strength
- In swimming, the core has a central role, since it affects our ability to maintain the body’s position in the water. A strong core also gives us a better rotation and is said to give a better swimming technique (see swimming strength).
- When we ride our bikes, of course, your legs have to work hardest, but your muscles in our core need to be strong in order for you to be able to maintain your position on the bike. Static work. If we have a weak body, the upper body will collapse somewhat and we will lose power.
- During running we need a stable and sustained musculature in the core so that you can maintain a good posture. If we succeed in this, it results in better breathing and we get a more efficient and better running step (see running strength).
When training your core, it is extremely important to think about the technique.
11 exercises for your core
We recommend you to do core training three times per week! The following videos are presented in Swedish but explained in text in English.
- Start by laying down with your stomach against the floor resting on your forearms. With the elbows directly under the shoulders, you lift the torso from the ground so that the body forms a straight line from the upper body to the heels.
- Your body weight rests on your forearms and toes. Tighten your stomach and don’t let your hips sink. Your shoulder and elbow should be in a straight line.
- Start on your stomach with your hands held right by your ears. Focus your gaze down on the ground so you can relax your neck while doing the exercise. Lift yourself up so that you feel the lower back work. Activate your glutes throughout the exercise.
- If you raise your arms and hands are stretched over the head, this increases the difficulty level.
- Back extensions can also be done statically. That means that the body is kept in the same position all the time with the muscles activated.
- Lay on your back with your knees at a 90-degree angle to your feet.
- Lift hips and back from the floor so that the body forms a straight line from the shoulder to the knee.
