Due to flat feet and leg length asymmetry I have , my right piriformis and iliopsoas is almost always stiff. I discovered this issue at an age of 29 and the issue is being solved by foot insoles which already help tremendously.
Currently, I visit my physician once in 2 to 3 weeks for a dry needling session to loosen the gluteal area. After each session, my hips are somehow re-stationed well. After a year of treatment till now, my deadlift sessions (started at 4 reps 22,5kg of 1RM: 30kg) end up with a PR at 90% of my 1RM (8 reps of 102,5kg 1RM: 142,5kg).
I have tried to loosen those trigger points in the problem area with a- foamroll, 8kg medicine ball, lacrosse ball, golf ball, large marble and etc... but somehow no matter how hard try, doesn't work as well as dry needling. Sometimes the muscles don't even budge even after 20 minutes of focussed pressure. Of course I make sure to react to pain when necessary and stop the attempt when it is uncomfortable.
P.S.: I always do my release attempt symmetrical, so whenever I attempt to release, I try it on both sides to prevent future imbalances.
Any ideas how to cope with this?
I want to give a try to Pavel Tsatsouline's beyond stretching, but I wanna prepare for it first and don't want to go further while I am having this annoying challenge.
