Starfish Crunches Exercise

Introduction

The Starfish Crunch is an effective core-strengthening exercise that targets the abdominal muscles, especially the rectus abdominis and obliques.

In yoga, the starfish crunch practice is also called Star Crunch or Vasisthasana Starfish. This workout targets the rectus abdominis, hip flexors, and internal and external obliques. The exercise involves lying down with your arms and legs extended and reaching for the opposing arm and leg.

The Starfish Crunch, a variation on the classic abdominal crunch, includes elevating opposing limbs (arm and leg) in the direction of one another while resting in the “X” setup. The action’s approximation of a starfish folding in is where the word originates.
Starfish Crunch not only improves your coordination and strengthens your abdominal muscles, but it also causes neuromuscular problems.

Muscles Worked

• Rectus Abdominis
• Side abs, or obliques
• Transversus Abdominis (deep core muscles)
• Hip flexors
• Quadriceps
• Shoulders Flexors

How to do Starfish Crunches?

• To make your body mimic a starfish, spread your arms and legs wide and lie on your back.
• Raise one leg and the arm of the opposing side gradually until they reach the center while keeping these body parts outstretched. For these movements, you should activate your core muscles as much as you can.
• Lower your arm and leg through their whole range of motion in a controlled motion to the position described in step 1.
• Do the same movement with the opposing arm and leg as many times as you can.

Benefits

If you enjoy performing them, starfish crunches may be quite useful, but you can get many of the same benefits from many other exercises. Make sure your body receives enough food, rest, and sleep if you want to start doing more starfish crunches so that your muscles can develop and repair. Never forget that lifting weights and exercising may both help you burn calories.

Many people may benefit from incorporating starfish crunches into their fitness routine. You might need to use crunch equipment to enhance the intensity of your workout if you want to continue seeing considerable muscle growth and gain strength more quickly.

Variations of Starfish Crunches

Performing starfish crunches with your arms straight overhead and just your body weight is a common version of the exercise. There are a few variations that might make the exercise harder or easier because some people are not ready for full starfish crunches just yet.

For Less Intensity

To acquire the full version, you could consider just slightly elevating your body parts. If it’s still too hard, you may start by lying on your back and pressing your lower back into the floor using your abdominal muscles.
If your oblique muscles are keeping you from pushing forward, you can start with side planks or even knee side planks. With each of these variations, you may work similar muscles at a less challenging level.

For Increased Intensity

Bodyweight starfish crunches might sometimes become overly easy. You may need to change up your workouts or make starfish crunches more challenging if you want to keep seeing significant improvements in strength and muscle building at this point.
Making starfish crunches more challenging at the right points in your training journey will help accelerate your growth as opposed to continuously completing the regular bodyweight type.
