I started training for the planche one again (I hope consistently this time) and I just discovered that I have horrible straight arm strength. I used to to the progressions with slightly bent arms (didn't notice) and it makes a huge difference. I'm just horrible, I can't do tuck planche for more than 3 seconds and at the advanced frog stand, my elbows kinda hurt because of the weight applied from my feet. It's very unconfortable. I think I may be doing something wrong.
I consider myself competent at most exercises so it's a little surprising for me that I'm so bad at the planche.
Despite all that, I can perform several pseudo planche pushups (like the ones demonstrated by slizzardman in his planche pushup video).
Suggestions?
