really need help
First time on this subreddit and only trying to have some questions answered since it's been bogging my mind for half a year already. Basically around November last year, i went for a PR on the deadlift, and easily lifted 180kg and 200kg, then after the following weeks, i noticed that my strength has declined, since i deadlifted 200kg without a proper powerlifting program, i just thought it was because my CNS was fried so i just thought i should recover, not until like later the next year, i never got close to deadlifting even 170kg for reps so i started wondering what happened, but my squat and bench are slowly progressing, so naturally i just thought i needed to opt for a program and a deload but even after that it was the same, now im starting to doubt myself if i can even hit numbers again. If anyone can please know and tell why it's like this
Very much appreciated.
