  2. Place your hands behind your head and lock them together by clasping your fingers. This is the starting position.
  3. Elevate your upper body so that it creates an imaginary V-shape with your thighs. Breathe out when performing this part of the exercise.
  4. Once you feel the contraction for a second, lower your upper body back down to the starting position while inhaling.
  5. Repeat for the recommended amount of repetitions.

How to use Sit-Up — How to, Muscles, Form

Best for: Building practical strength and adding focused work for Abdominals. Use it when the movement fits your goal, equipment, and recovery.

Programming tip: Start with a load you can control for every rep. Add reps before adding weight, and keep the last rep clean enough that you could repeat the movement next week.

Common mistake: Chasing heavier weight before the setup, range of motion, and tempo are consistent. If the rep changes every set, the log stops telling the truth.

Track it: Log weight, reps, sets, and one short note about form or difficulty. Over time, those notes explain plateaus better than motivation quotes ever will.
