Your core isn’t just there to help you get a six-pack. It’s there to help you control movement.
A lot of athletes train their core with exercises that only challenge one thing:
🔥 Burning the abs
But endurance sports require much more than that.
When you run, cycle, or swim, your core has to help you:
✅ Transfer force efficiently
✅ Control rotation
✅ Maintain posture when fatigued
✅ Keep your movements coordinated
The hanging knee tuck is a great way to challenge your core because you have to stabilize your entire body while moving your legs.
The key is control.
Don’t swing.
Don’t use momentum.
Don’t let your body rotate all over the place.
Focus on:
✔ Active shoulders
✔ Controlled movement
✔ Keeping your ribs and pelvis connected
✔ Smooth, efficient repetitions
Bonus: You’re also building grip strength...something that is important for overall strength and longevity.
