Whenever I do planche my protraction is good for first few seconds but after that it goes to neutral position and all my sets are the same what should I do?

I did 5-6 sets of PL And FL holds and then did 2 supersets of HSPU and bent over rows

I lost my strength i could do straddle planche but now I am struggling to do bent arm press and advanced tuck planche hold due to this I had a 2-3 days of rest even then I feel weak.What should I do?

I am stuck at advanced tuck planche,even though after a full day of rest I cannot hold the straddle planche for even i 1 second so what should I do ?
