I'm on my first HST cycle and today was my third workout for my 15 rep 2 week block. The first two workouts were great, but on the third the problem was that I couldn't get to 15 reps on a few exercises. I got about 12. Is this a big problem? My max for 15 reps on those exercises was more weight than I did today when I tested my maxes, but for some reason I couldn't get up to 15. Maybe I'm not used to this frequency even though the volume is lower. My body must have still been fatigued from working out on Wednesday. What should I do? Does this go against the program if I failed to hit 15 reps? Or will I still see good gains because of the workout frequency? Thanks.
