2. GHD SIT UPS
Whilst we are on the subject of the GHD, why not tackle the other side? GHD Sit Ups are an awesome help to lengthen your hip flexors and get them ready for those squats. Of course they also strengthen your core, which will improve your physical abilities as your core is almost always used in every exercise and movement. From a Deadlift to a kipping movement on the bar, a stronger core will be nothing but an asset. Not to forget the welcome side effect of some ripped abs as well.
