The hanging leg raise is great for working the abs in a way that transfers to many sporting and performance-based activities. They are required to hold a strong isometric contraction which is vital for transferring force during the prior mentioned activities. The legs create the resistance and having them straight out makes things tonnes more difficult. Remember to keep good control, especially eccentrically on the way down to get the most out of these. Make sure you have mastered the hanging knee raise before moving onto these.
The hanging knee raise is a great exercise for not only working the abs and bracing but integrating the active hang and pullup strength. You better have a decent level of upper body strength as you will be required to hang from a pullup bar just to be able to do this exercise. If you can hang, you should be able to do some good work through your core but your strength will dictate how controlled and how many you can do.
The Good Morning is a hip hinge movement and is very similar to the Romanian Deadlift in terms of execution. The only difference is where the weight is loaded and thus how it challenges the muscles involved. A well-executed good morning relies on a good hinge pattern. It can be inherently risking due to the forward lean and placement of the weight on the back so it is important to take this into consideration before planning it within your routine.
The Romanian deadlift is a great exercise to develop the hips and posterior chain. It is one of the foundational hip hinge movements and should be mastered to form the basis of any power development exercises. The Romanian deadlift can be a tricky one to pick up but it is always a good place to start for those newer to any form of deadlifting and always provides a useful tool for developing muscle and strength in the glutes, hamstrings and lower back.
