I read a comment on YouTube stating that some people, no matter how hard they train, may never be able to achieve a full planche in their lifetime due to genetics - that some people may not have been born with "enough" joints in their shoulders/elbows to ever achieve a full planche. That's why some people plateau at straddle planche for months/years and never see progress. Or they're just downright too heavy. Now I know there are stories of some heavy & successful acrobats, but they must have some amazing genetics to be able to do it. Maybe they were lighter when they learned those acrobatic moves, and then decided to bulk up.

Full planche at 2:04.
I did not want to start a new thread on nutrition, but I just wanted to know how effective a diet is for planche training. I was talking to another guy and he claimed to achieve a four second full planche in 5 months, where as it took me twice as long to hold an almost decent planche for 3 seconds. He did tell me that his "joints were killing me" and that he should have been more patient and trained more slowly/carefully. He says it's not too bad anymore though.
I asked him what his diet consisted of and he told me that for joint health/strength he ate one apple and raw broccoli (he did not specify the amount, so I'll go with one cup) everyday and various fruits throughout the week. He also took a supplement called glucosamine sulfate. He did not specify the amount but I would probably start out with one serving a day and work my way up to two servings a day.
I've heard some successful full "planchers" say that it takes about 1 - 2 years, and once your past that threshold, it's likely you'll never get a full planche.
How valid do you think that theory and diet is? Of course this is all just pure speculation, so I just wanted to get your opinions.
EDIT:
It has come to my attention that he has a background in lifting weights (2x BW Bench Press) and 10 months of calisthenics prior to planche training, so it's only natural that he would progress more quickly towards the full planche. I don't have a background in lifting weights nor did I practice any of the static progression with ankle weights/weighted vest, so it's understandable that my progression would be slower.
I think the majority consensus (on this thread) is that when it comes to training for the full planche, diet does not really play a significant role in progressing quickly.
