Started a workout from Metroflex Powerbuilding basics and the first two weeks I had INCREDIBLE results, 3RM on Bench press up 10 kg (22bs), 5RM on the Squat up 12 kg and Deadlift up 10 kg. i did none of the exercises to failure either. However today at the gym (first day of week 3) I could BARELY squeeze out one rep on the bench press with the same weight I used last week.
My diet has been the same as usual and I have been sleeping about 10 hours a night(. Would it be beneficial for me to deload this week and then try to increase the weight next week?
