Health Benefits

This exercise targets several muscle groups and provides numerous health benefits, which include:

1) Improved core strength

Jackknife sit-ups work the rectus abdominis muscle, which is responsible for flexing the spine and bringing the ribcage closer to the pelvis. Strengthening this muscle can improve your overall core strength, which can improve your posture, reduce lower back pain, and enhance athletic performance.

---

2) Increased stability and balance

Jackknife sit-ups also engage the hip flexors and lower back muscles, which help to stabilize the spine. This can improve your balance and stability, making it easier to perform daily activities and reduce the risk of falls and injuries.

3) Improved flexibility

Jackknife sit-ups require a high level of flexibility in the hamstrings and lower back. As you perform this exercise, you can increase your flexibility and range of motion in these areas.
