Sit-ups vs. Squats: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on February 22, 2024
Sit-ups are a core-strengthening exercise focusing on the abdominal muscles, whereas squats are a lower-body workout targeting thighs, hips, and buttocks.

Key Differences

Sit-ups primarily work the abdominal muscles, aiding in core strengthening and stability. Squats focus on the lower body, targeting the quadriceps, hamstrings, glutes, and lower back muscles.
Sit-ups involve lying on your back and lifting your torso towards your knees. Squats require standing with feet shoulder-width apart and lowering the body by bending the knees, keeping the back straight.
Sit-ups aim to improve core strength, which is vital for balance and posture. Squats are effective for building lower body strength, improving flexibility, and supporting joint health.
Sit-ups can be modified for beginners by reducing the range of motion. Squats can be adjusted by altering depth, adding weights, or changing foot positioning for varied intensity.
Incorrect form in sit-ups can strain the neck and back. Squats, if performed improperly, can lead to knee and lower back injuries.
