Sprinter Sit-Ups ✅: Good for dynamic core strength and coordinating trunk movement with athletic positions. Crunches ❌: Limited carryover to sprinting, cutting, and explosive athletic movements. Deadbugs ✅: Good for core stability, coordination, and controlling your trunk while your limbs move. Flutter Kicks ❌: Can become more about hip-flexor endurance than effective core stability. Planks ✅: Good for building core stiffness and resisting unwanted movement. Bad Form Russian Twists ❌: Poor form can create unnecessary spinal movement without giving you much athletic benefit. Mountain Climbers ✅: Good for core stability while moving the limbs and maintaining body control. Bicycle Crunches ❌: Often become a high-rep ab exercise with limited athletic carryover when performed quickly or with poor control. Train your core for athletic performance, not just an ab burn.
