I go first

Do u guys think sharp pain interrupts your cns from recovering? Or do u guys think its just two different things?

I add 27kg to dips using a backpack but the backpack is pulling me backwards which makes dips harder and less comfortable. What should I do? I workout from home

I wanted to know what is the best way to train abs(for strength for future skills and exercise as well as just having a well rounded physique) Until now I just did a single ab exercise at the end of each workout(hanging straight leg raises after pull workout, weighted hollow hold after push workout, and hanging straight leg raises again after upper), but I realized I don't train the obliques, and that my way of training is not optimized(as my grip fails before my abs on hanging straight leg raises due to it being fatigued from earlier exercises) Anyways thanks in advance!

Should I change push and pull days to high rep low intensity days and do another upper day focused only on strength or the other way around or maybe it isn't a good idea at all? My main focus is gaining strength and I can workout only 5 times a week - Sunday to Thursday What do you all think? Thanks in advance!
