A strong and defined stomach is not only aesthetically desirable , but above all, extremely important functionally. The abdominal muscles form the central foundation for a stable core , protect the spine , and ensure efficient power transfer in all movements. Nevertheless, most training programs repeatedly use the same classic exercises like sit-ups or crunches – often with limited success and with the risk of causing tension or pain.
That's why today we're introducing you to five little-known but extremely effective exercises that train your abdominal muscles holistically. They strengthen not only the visible muscles, but also the deeper layers that ensure stability and posture. With the right equipment from Atletica , you can easily integrate these exercises into your workout and thus sustainably improve your core strength.

1. Dead Bug – The ultimate exercise for the deep abdominal muscles
The dead bug is a fantastic exercise that is often underestimated . It activates the deep transversus abdominis muscles, which act as natural corset muscles to protect the lower back and improve posture.
Execution :
- Lie on your back and stretch your arms vertically upwards.
- Raise your legs to a 90-degree angle, knees above your hips.
- Slowly stretch one leg straight forward and at the same time stretch the opposite arm backward.
- Make sure your lower back stays flat on the floor throughout the movement.
- Return to the starting position and switch sides.
Why is the Dead Bug so effective?
This exercise teaches you to consciously activate your core muscles without straining your lumbar spine. The dead bug is ideal for building a stable core, especially for people with back problems or beginners .
Equipment tip: You can increase the difficulty level with Atletica ankle weights .

2. Hollow Body Hold – More than just an abdominal exercise

6. Why lesser-known abdominal exercises are often more effective
Many well-known abdominal exercises focus on the visible muscles (rectus abdominis) and neglect the deep muscles that provide stability . The consequences can be muscular imbalances, back pain , and poor posture.
The exercises presented train the core holistically and promote not only muscle strength, but also coordination, balance and posture.
