butterfly-crunches

Butterfly Crunches target the rectus abdominis muscle. In terms of target muscles, there are hardly any differences compared to traditional crunches. Additionally, the pyramidalis muscle is also stimulated. The supporting musculature mainly involves the obliquus abdominis muscle.

Classic butterfly crunches

The traditional Butterfly Crunches are closely related to the popular Butterfly Sit-Ups. However, instead of the typical Sit-Up movement, the Crunch movement is performed in this case. A distinctive feature of this variation is the butterfly position of the thighs. In the following section, you will receive all relevant information about the optimal body position and execution.

Body Position

For the traditional Butterfly Crunches, lie flat on the floor. Start by bending your legs on the ground, and then let your knees fall outward so that the soles of your feet touch in the middle. The spine should be fully stretched, and your hands should be positioned slightly beside your head.

Execution of the Movement

The Butterfly Crunches begin by contracting the abdominal muscles. Then, slowly lift your upper body upward, exhaling as you perform the classic Crunch movement. The lower back remains fully on the floor. At the same time, lift the bent legs upward, so that elbows and knees almost touch. The head remains extended along the spine, and the back is approximately at a 45-degree angle upward. Ideally, the feet should be at the level of the head at the end of the movement. Now, you can breathe in comfortably and return to the starting position before starting the next repetition.

Butterfly crunch with a ball

In addition to the common Ball Crunches, the Pezzi ball is also suitable for special exercise variations such as the Ball Butterfly Crunches described here. At the same time, the ball allows for the performance of other abdominal fitness exercises, such as Ball Sit-Ups, upper body bends with the ball, and jackknife with the ball. However, the focus in the following section is on the Butterfly Crunches with a ball.

Body Position

In the starting position, lie on your back on the floor, hands on both sides of your head, and look upward. A ball is clamped between your legs. The legs are slightly inclined outward, with the calves fixing the ball with their inner side.

Execution of the Movement

To start the exercise, lift your upper body and exhale. The upward movement should be such that your upper body is approximately at a 45-degree angle from the floor. At the same time, lift the legs with the ball so that the upper body and ball are close to each other. The head almost touches the ball, while elbows and knees are brought together. Ensure that the lower back remains on the floor throughout the entire time.

Common Frog Crunch Mistakes

When errors occur during the execution of fitness exercises, the full potential is not realized. This has a negative impact on training success and poses potential risks of injury. Therefore, this section highlights the typical mistakes in Frog Crunches, accompanied by advice on how to avoid them.

✅ Head not an extension of the spine: It is not uncommon to see athletes improperly positioning their heads during Frog Crunches. This posture can increase the risk of injuries in the neck region.

✅ Head and elbows too far from the legs: It is advisable to position the head and elbows close to the legs. It is crucial to maintain tension in the abdomen to ensure maximum training effectiveness.

✅ Swinging from the entire body: In Frog Crunches, the movement should originate from the abdomen. Keep the arms still at the head and move the legs moderately to avoid diminishing the effectiveness of the workout.
