Butterfly Sit Ups

Butterfly sit ups are a core-strengthening exercise where you perform a full range of motion sit-up with the soles of your feet pressed together and knees dropped out to the sides, minimizing hip flexor involvement and placing more emphasis on the abdominal muscles. This variation increases core engagement, improves flexibility in the hips, and helps build stronger, more controlled abdominals, making it an excellent addition to bodyweight workouts, core circuits, and functional fitness programs.
