Anatomy of the Advanced Move
In a video shared by fitness expert Karan Sawhney, Kriti Sanon is seen performing a highly advanced variation of a hanging leg movement. While suspended from an overhead bar, she rapidly kicks a stability ball held in front of her. This exercise might
look straightforward, but it’s a complex, compound movement that engages multiple muscle groups simultaneously. To perform it, one needs exceptional core control to prevent the body from swinging, strong grip and shoulders to support her entire body weight, and coordinated hip flexors to drive the fast leg kicks. It’s a true test of stability, strength, and body awareness all rolled into one.
The Power of an Unstable Surface
The secret ingredient that makes this workout so tough is the stability ball. Training on an unstable surface forces your deep core muscles to work overtime to maintain balance. While a standard hanging leg raise is already a great core exercise, adding the ball introduces a coordination challenge. Sanon must constantly adjust and stabilise her torso and pelvis while her legs move quickly, significantly increasing the demand on her abdominal muscles. This type of training improves not just strength but also proprioception—your body's awareness of its position in space. The instability forces smaller, stabilising muscles around the core, spine, and hips to fire, leading to a more comprehensive and functional workout than exercises on a stable surface.
Why Grip Strength Is a Fitness Game-Changer
One of the most underrated components of this exercise is the immense grip strength required. Holding your bodyweight while performing other movements is no easy feat. Your grip is often the first thing to fatigue in exercises like pull-ups and deadlifts, limiting your ability to fully work larger muscle groups. But grip strength is more than just a gateway to lifting heavier; it's a key indicator of overall health and longevity. Research has linked lower grip strength to a higher risk of chronic disease and reduced physical independence later in life. By incorporating exercises that challenge the hands and forearms, you not only improve your performance in the gym but also support your long-term health and prevent injuries in the wrists, elbows, and shoulders.
Fast Leg Movement for Agility and Power
The rapid, alternating kicks in this workout are a form of dynamic leg movement that builds functional fitness. This is different from slow, controlled lifts. The quick kicks engage fast-twitch muscle fibers, which are crucial for explosive power, speed, and agility. Think about the quick direction changes needed in sports or simply reacting to a stumble on the street. Furthermore, this high-energy movement helps elevate the heart rate, incorporating a cardiovascular element into a strength-focused routine. The exercise effectively trains the hip flexors, quads, and lower abs to work in a coordinated, powerful fashion, which is essential for everything from running to climbing stairs.
How to Build Up to This Move Safely
This is an advanced exercise, and experts caution against trying it without building a solid foundation first. Jumping into it too soon can lead to injury. To work your way up, start by mastering the basics. Begin with simple dead hangs from a pull-up bar to build grip strength and shoulder stability. Practice basic floor exercises with a stability ball, like crunches and planks, to improve your core control on an unstable surface. Once you feel comfortable, you can progress to hanging knee tucks and slow, controlled leg raises without the ball. When you can do those with perfect form, you can introduce the ball, perhaps starting with single, slow leg presses against it before attempting rapid kicks. The key is to progress gradually and listen to your body, focusing on control over speed.
