The core is a group of muscles that surround your trunk, including your abdominals, obliques, diaphragm, pelvic floor, trunk extensors, and hip flexors. Core muscles are important for everyday activities such as breathing, posture control, urination, and defecation. They also provide stability to your trunk for balance and for movements like lifting weights and standing up from a chair. Engaging your core muscles can be done in several ways, including breathing and crunches.
| Characteristics | Values |
|---|---|
| Definition | The core refers to the main muscles that move, support, and stabilize the spine. |
| Location | The core includes the muscles surrounding the trunk, from the abdominals to the lower back and pelvis. |
| Composition | The core consists of several muscle groups, including the rectus abdominis, internal and external obliques, transversus abdominis, iliopsoas, abdominals, pelvic floor, diaphragm, back extensors, and some hip flexors. |
| Function | The core provides stability, balance, and mobility to the trunk, enabling movements like lifting weights, standing up, and swinging. It is also involved in everyday activities such as breathing, posture control, and urination. |
| Benefits of a Strong Core | A strong core improves overall fitness, enhances spinal support and stability, reduces the risk of injuries, and improves balance and coordination. |
| Exercises | Beginner exercises include crunches, bird dog, and basic planks. Intermediate to advanced exercises include combining planks with knee movements and side planks with arm movements. |
| Technique | Engaging the core involves bracing and tightening the core muscles to create a strong cylinder from the rib cage to the pelvis. This can be done by inhaling and imagining bringing the belly button toward the spine. |

What You'll Learn
The importance of breathing
Breathing is an essential aspect of engaging your core muscles. When you breathe, you have the opportunity to engage your core and create a strong cylinder of muscles from your ribs to your hips. This is achieved by bracing and tightening your abdominal muscles while inhaling and exhaling.
The diaphragm, a crucial component of the core, plays a significant role in breathing by facilitating airflow into and out of the lungs. Engaging the diaphragm and other core muscles during breathing helps to stabilise your trunk, ensuring balance and supporting movements like lifting weights or standing up from a chair.
Professional powerlifters and Olympic weightlifters provide a notable example of the importance of breathing in core engagement. When these athletes perform lifts, they use their breath to push against their weightlifting belts, providing additional support for their spines. By engaging their core muscles and utilising the belt's responding pressure, they safeguard their spines while handling substantial weights.
Furthermore, proper breathing while engaging your core is essential for injury prevention. A weak core can lead to debilitating issues such as lower back and hip pain, hernias, and abdominal strains. By strengthening your core through correct breathing techniques, you can reduce the risk of sustaining injuries during exercise and everyday activities.
To summarise, breathing is fundamental to engaging your core effectively. It allows you to activate and coordinate the various muscles that comprise the core, resulting in improved stability, balance, and injury prevention. By focusing on breathing correctly during core exercises, you can enhance your overall core strength and resilience.

How to do it
- Begin on all fours, with your hands placed directly under your shoulders and your knees placed directly under your hips. Your back should be straight and your neck and head in a neutral position, looking down at the floor.
- Tighten your abdominal muscles and slowly lift your left arm out in front of you, straight out from the shoulder, while simultaneously lifting your right leg out behind you, straight out from the hip. Keep your arm and leg parallel to the floor.
- Hold the pose for a moment, balancing on your right hand and left knee.
- Slowly lower your arm and leg back to the starting position.
- Repeat with the opposite arm and leg.
Tips
- Keep your back straight and your neck and head in a neutral position throughout the movement.
- Avoid arching your back or twisting your neck to look at your moving arm and leg.
- Keep your movements slow and controlled.
- Focus on maintaining your balance and stability throughout the exercise.
- Aim for 8-10 repetitions on each side, and work towards completing 2-3 sets.

Plank with knee movements
Planks are an excellent way to strengthen your core. The plank with knee movements is an advanced variation of the basic plank that adds balance and core strength to the benefits of the traditional plank. Here is how you can do it:
How to do a Plank with Knee Movements:
- Start in a full plank position with your hands directly under your shoulders. Place your hands slightly wider than your shoulders and use your upper body and pelvis to stabilize yourself. Keep your back straight and your hips down.
- Tighten your core and engage your abdominal muscles.
- Lift your right knee toward your chest without rotating your hips or shoulders.
- Return your right leg to the starting position and simultaneously lift your left knee toward your chest.
- Continue alternating legs for 20-30 seconds or as long as you can maintain proper form.
Tips:
- As you become more comfortable with the movement, you can increase your speed. The faster you go, the more cardiovascular benefits you gain. However, always maintain proper form.
- If you are a beginner or find the full plank too challenging, you can modify this exercise by performing it from your knees and forearms (or palms of your hands). This variation is called a Plank on Knees and is a great way to build up to the full plank position.
- If you experience any knee discomfort during the Plank on Knees, you can place more padding under your knees for cushioning.
- To increase the intensity, try a Plank with Shoulder Taps. Start in a traditional straight-arm plank position and lift your right hand off the floor to touch your left shoulder. Then, return your right hand to the floor and repeat on the other side. Avoid rotating your shoulders or hips, and focus on keeping your body in a straight line.
The plank with knee movements is an excellent exercise to build core strength, balance, and coordination. Remember to listen to your body and adjust the exercise as needed.

Crunches
To perform a standard crunch, lie flat on your back on a comfortable surface, such as an exercise mat or a soft towel. You can also do crunches on a carpeted floor. Bend your knees and plant your feet flat on the floor, hip-width apart, with your heels about 12 to 18 inches (30 to 46 cm) from your tailbone. Cross your arms in front of your chest, with your hands just below your shoulders and your elbows pointed down towards your feet. Engage your abs and push your lower back flat against the mat to ensure your core stays engaged. Avoid sitting all the way up, as this can strain your back and hips. Instead, lift your head and shoulders off the floor and hold this position for 1-2 counts. Then, slowly lower yourself back down. Repeat this for 10-12 reps to start with, and work your way up to 2-3 sets as you build core strength.
You can also try variations of the basic crunch, such as the bicycle crunch or reverse crunch, to target different muscle groups and switch up your workout routine. For example, in the bicycle crunch, you would lift your knees to 90 degrees and rotate your trunk, moving your opposite elbow and knee towards each other while straightening your other leg. This works both your abs and obliques.

The superman
Begin by lying flat on your stomach with your legs extended straight behind you and your arms extended straight in front. Ensure your neck is in a neutral position and your gaze is directed towards the floor. This is your starting position.
As you inhale, slowly lift your arms, chest, and legs off the floor simultaneously, creating a 'U' shape with your body. You should feel a contraction in your back, glutes, and hamstrings. At the top of the movement, pause and squeeze your muscles for a moment, ensuring your core is engaged.
Exhale as you slowly lower your arms, chest, and legs back down to the starting position, again maintaining control throughout the movement. That is one rep.
Aim for 3 sets of 10-15 reps, depending on your fitness level and comfort. Remember to keep your neck neutral and your gaze down throughout the exercise to maintain proper form and protect your neck.
This exercise can be modified by lifting opposite arm and leg, or by performing the movement with one side at a time, to increase the challenge and target your muscles differently.
