I do not have the mobility to maintain a PPT when flat on the floor and when I weight my quads I still don't have the mobility to PPT. I have to raise my legs off the ground to PPT. I was a race cyclist for a number of years resulting in very tight quads.
I know lack of quad mobility etc is my limiter and a big limiter for progression in a wide range of areas. I have addressed this by: I have doubled the quad stretching on the front splits videos, I have also completed the middle and front splits mobility drills consistently for 7 months. While my hamstrings, calf's etc are more open I have seen very little improvement in my quad/ psoas mobility. I also have added deadlifting to my programme to stimulate the posterior chain.
Can you suggest whether there is an alternative E4 drill I should complete? And are there any additional quad mobility/PPT exercises I could do to improve my quad/psoas mobility?
