Like the posters above said it’s probably not the program. If you’ve run it properly then you shouldn’t be having issues. Is this your first time running the program?
If you have followed the program properly ask Chad Wesley Smith for a refund. Look into his cute little baby blue eyes and tell him" Your program is rubbish you teddy bear arse looking motherfucker."
Possibly is just fatigue catching up to you: Fatigue masks fitness and all that jazz
Sounds like you’re overly fatigued or overreached tho. Probably a bit of fatigue mismanagement going on. Is your diet and sleep on point? Are outside stressors e.g. Work, personal, health etc. taking away from your recovery abilities?
Fatigue mismanagement also includes training i.e not doing the program properly and thus accummating excessive fatigue and not dissipating it successfully.
May as well finish what you’ve started. Hell throw in a random deload if it’s already so fucked.
Most importantly take as long as you need to reflect on why you’ve not performed as well as you’d like and learn from it. You have your training logs, the program and your memory which should be plenty to go off of.
It’s not particularly complicated look at the when/where and why/how you went off the rails whether that be from the vey start or just one week that was fucked up.
If you have a history or doing poorly on programs either you picked shit like bodybuilding.com’s bigger biceps in 10 days or you’ve messed up in running popular well proven programs. If you can determine why then you can avoid messing up future programs.
