Thursday Core and Make-Up Day
GHD sit ups, if done properly, can be a great midline strengthening exercise. Done incorrectly it can lead to back pain, hip pain, and excessive abdominal pain. Key performance points in a GHD sit up are 1.) A neutral spine. No Hyper extension. 2.) Bent knees on the way down. Locked out legs on the down down can place increased strain on the low back and over stretch the abdominals. 3.) Explosive knee extension, leg straightening, while holding a straight spine will reduce unnecessary strain of the back and abdominal muscles. Slowly build your GHD capacity over time to reduce risk of injury or heavy delayed onset muscle soreness.
