Oblique HIIT Workout – Core HIIT Series (Crunch & Twist Part 2)

If you want a balanced midsection, you can’t just train the six-pack muscles. Your obliques — the muscles down the side of your core — are essential for rotation, balance, and overall strength. This oblique HIIT workout will challenge your side abs with three killer moves.

The Workout

• 35 seconds work per move

Benefits of This Oblique HIIT Workout

• Russian Twist: Builds rotational strength and endurance.

• Alternating Cross-Body V-Up: Combines a V-up with a twist, training abs and obliques together.

Why Obliques Matter

Strong obliques do more than make your core look sharp. They:

• Protect your lower back from rotation injuries

• Improve athletic power in sports like football, boxing, and golf

• Build real-world stability and balance
