#shorts Introducing sit-ups to your workouts is one way to help boost your core strength. These abs exercises can be performed without equipment, which means you can do them anywhere, whether in or out of the gym. Today we will discuss two sit-up variations and their biomechanical differences and EMG activation. The Traditional Sit-Up ⬇️ In this exercise, your legs are flat on the ground. When performing this sit-up, your hip flexors (particularly the rectus femoris) help more during the sit-up.[1] The Modified Bent-Knee Sit-Up ⬆️ Contrary to the traditional sit-up, in this exercise your knee is bent, and your hip is fixed in flexion. A study by Sullivan et al. (2015) showed greater EMG activity of the rectus abdominis and external oblique during the modified sit-up. Did you know this study also found that when subjects were instructed to emphasize hip flexion, the EMG activity was more significant than when no specific instruction
