I am nearly on foundation 3 for all my exs, except front lever where i am on straddle body rocks; i cannot get beyond 48x2 or 60x1 or 36x5. I have tried every variation for months, had gymnasts tell me my form is fine. My core just tires and my other muscles start to take over. I am pretty much ready to just skip to full body rocks and get to 4x36 or 1x60 or 3x48 as i will likely stall there too and move on. I am getting so close to front lever variations of rope climb and no where to go...
any suggestions??
