What is a sit-up?
Sit-ups improve the abdominal muscles and tone the core. They entail laying on your back on the floor and elevating your torso. Sit-ups offer a larger range of motion than crunches, making them more effective in targeting several muscles.
Sit-ups primarily target the rectus abdominis muscles, which run vertically across the front of the torso (1). These exercises target the transverse and oblique abdominal muscles, promoting sculpted abs. Sit-ups also aid with posture by training the hip flexors, which connect the thighs to the lower back and gluteal muscles. Sit-ups are simple to execute if you use the proper methods.
