Bosu Ball Cable Crunch With Side Bends

What it is

This movement challenges your core stability and strength. You will primarily work your abdominal muscles through a controlled cable crunch. The dynamic side bends further engage your obliques for a comprehensive midsection workout.

Technique tips

• Position the Bosu Ball to comfortably arch your lower back.
• Keep your arms straight and follow the cable's line upward.
• Exhale as you crunch; inhale slowly on the return.
• Prevent your glutes from touching the floor for constant tension.
• Reach for your heels during the side bends to engage obliques.
• Control the descent to maximize the abdominal stretch.

How to track your progress

Log the weight and reps of each set. Straddly turns every set into an estimated one-rep max, so a heavier single and a strong set of eight both count as progress, and it flags a personal record the moment you beat your best.
