It needs to be stressed – this is no beginners piece of equipment. Many coaches recommend to start training on a GHD, only when sit-ups, plank and hanging knee raises have been fully mastered, to avoid unnecessary injuries.The GHD is one of the best exercising tools, where athletes learn how to generate power from their hips. On it we can perform one of the most effective isometric core exercises.Fortified GHD is the Royal GHD upgrade. It offers 10 different settings, so anyone can adjust it according their needs and preferences. The structure itself is from 3mm thick steel, while the base is of triangular shape which offers greater stability. The rubber on the bottom side prevents against sliding and keeps it in place. Moreover, it is also equipped with wheels for easier moving around the room.
