Im a beginner, 6’0 155lb. Ive been runnign starting strength for three weeks, before that was stronglifts. Same problem thats happened to me with stronglifts is currently happening to me with SS now. I made good progress on SS for the first two weeks but this week has been rough- I cut weight back by 15% and still had to decrease more today. Its not my diet, I dont think so anyways, since my weight has been going up. The only thing I could think of is sleep which has been okay, but could be a little better, I usaully get 8-9 hours with some exceptions.
I do endurance training too. Im looking for a good program to supplement this without overdoing it. Im also a part time construction worker and a full time student. I have a lot of stress from my lifestyle so Im really looking for a good minimalist program. SS is a program Id like to stick with… it might be that Im not doing the program properly but I have never failed a lift, though I have had sets where I had to grind out the last few. Anyways, could it be that Im performing the lifts at too high of an intensity?
