Staff Sergeant Ken explains and performs perfect full sit up form for Army Physical Fitness Test.
Requires:
90 degree angle at knees.
Heels on the ground.
Fingers clasped and behind head.
Ex-hale up, in-hale down.
Break vertical.
Recommends:
Feet elevated on bench to decrease strain on lower back for training.
Rest position:
Rest in up position.
My Thoughts:
If you have a weak core, poor flexibility, or have chronic back issues, stick to crunches! The only advantage of a sit up vs a crunch is that sit ups activate hip flexors in addition to abdominals. Which reminds me, stretch your hip flexors after doing sit ups or you may develop poor flexibility and chronic back issues!
