When most beginners train their core, they jump straight into endless crunches or sit-ups. The problem? Those don’t actually build the deep, functional strength your body needs for calisthenics.
The #1 core exercise most beginners skip is the Hollow Body Hold — and it’s a total game-changer.
🔥 Hollow Body Hold (Step-by-Step)
Lie flat on your back.
Lift your legs a few inches off the ground.
Raise your arms overhead and lift your shoulders slightly off the floor.
Keep your lower back pressed into the ground.
Hold for 15–30 seconds.
That’s it. Sounds simple, but it’ll light up your abs, strengthen your core, and improve every single calisthenics exercise (push-ups, pull-ups, handstands, you name it).
