Sit-up

What it is

This foundational core exercise strengthens your abdominal muscles by lifting your upper body from a lying position. You begin on your back with bent knees and use your core to raise your torso towards your thighs, creating a "V" shape. This movement primarily targets your abdominals and builds essential core strength. It is a bodyweight movement suitable for various fitness levels.

Technique tips

• Keep your feet securely anchored and knees bent at approximately 90 degrees.
• Place hands lightly behind your head, avoiding pulling on your neck.
• Exhale as you lift your torso, forming a V-shape with your thighs.
• Focus on controlled movement, not momentum, to raise your upper body.
• Inhale as you slowly lower your back to the starting position.
• Engage your core throughout the movement to protect your lower back.

How to track your progress

Log reps, and add the extra load if you wear a belt or a vest. Straddly counts your bodyweight in the estimated max, so added weight and extra reps both show up as progress, and new records are flagged during the session.
