Benefits Of The Double Crunch

Target Your Entire Core

As an exercise to target your entire core, the double crunch works to enhance all areas of strength to maximize performance, especially when it comes to big lifts and sport specific movements. You are able to work your core faster to develop those six-pack abs by targeting your upper and lower areas more effectively, as well as your obliques which can aid in that V-shape we all know and love (1).

Alleviate Back Pain

A strong core will work to alleviate any unwanted back pain that can arise from too much exercise or a grueling workout. By strengthening the base, your lower back won’t take much of the load often associated with lifting that bodybuilders and other athletes face. Back pain is an annoyance that no one wants and working to tackle areas that can help relieve it is more than important when looking to enhance training and performance (2).

Promote Better Posture

Bad posture is a curse that too many of us deal with. It would seem that improving our posture would be a no brainer but it is easier said than done. While doing posture improving exercises can be great for overall support, the double crunch provides for a more solid core to help improve your posture. A stronger core provides for a better base and will keep you more upright and less rounded for improved performance and more confidence.

Simple & Convenient

The double crunch can be done anywhere and at anytime making this an extremely convenient exercise. It is also simple to perform with no equipment needed so the stress of learning a new exercise is taken care of. We all want an easier exercise to improve our overall health and wellness and with the double crunch, we have just that.


How To Perform The Double Crunch

Here are the steps for performing a solid double crunch:

Start on the floor and lay on a mat or whatever is comfortable for you. Your knees will be best close to your chest and your feet slightly off the ground. Keeping your legs stretched as much as possible, keep them elevated off the ground while keeping your torso in a reclined position. Contracting your abs, raise your torso while bringing your knees to your chest. This will bring you back to the starting position where you can repeat for as many reps as you desire.


Things To Look Out For With The Double Crunch

Like any exercise, there are certain things to look out for in order to have an effective lift. These tips will keep you safe and away from unwanted pain while also maximizing the effects of the workout.

  • Breathing: Make sure to control your breathing. This will make sure you don’t tire yourself out too quickly while also maximizing range of motion for your muscles.
  • Don’t pull your head: Make sure to not yank your head for it not only takes away the effectiveness but also may cause pain.
  • Keep your hips planted: Raising your hips off the ground will disengage your core as well as cause pain in your low back since you are taking more load.

For those with low back pain, performing these exercises may make it worse. Really keeping your core tight can keep the load from attacking your low back. While this is a great exercise to strengthen your core, it can be a nuisance for those who unfortunately suffer from unwanted back pain.

Wrap Up

The double crunch is a great exercise to target your entire core with the added benefits of enhancing strength, making that physique pop, and working to improve posture and balance for big lifts. Keeping your core tight and engaged will prove to be more effective to decrease the load on your low back and provide for optimal effectiveness with each rep of the double crunch. Try this exercise next time you do abs and really feel the burn of this ab exercise.
