I have been working on planche for a while but I think the reason that I am progressing really slow is because of my weak hip flexors. Whenever I am in a straddle planche, I feel a lot of strain on my hip flexors. I think I have more than enough abs/back/shoulder strength but I think the hip flexors are holding me back from learning planche. Any ideas and anyone have any good suggestions on how to build strength on hip flexors?
I do L-sits and hanging leg raises in regular basis.
Thanks
