How should I eat?

I'm back on gymnastics(this time permanently) and I'm wondering about how my nutrition should be...

I have 2 goals:

1-To be proficiente with bodyweight strength movements(levers,planche)

2- want to be very muscular

My questions are will getting heavyer make things a lot harder for me in gymnastic skills and will be I still became very muscular at a light weight withoug having to eat tons of food?

I'm currently weighting 75 kg

try to go with a small calorie sufficit like 2-300 extra per day.. and read more about nutrition

If you get heavier by adding fat gymnastics will be harder. If you get heavier by adding muscle they will be easier.

One of my favorite examples:

Average vertical jump of power lifters is higher than the average vertical jump of NBA players.
