So I started lifting on Thursday last week and I found that I could lift pretty well or at least respectable beginner weights any way but I get burned out quickly. By that I mean a weight that I can easily do 8 reps with becomes too heavy for the next set.
8 X 75 seemed really easy
6 X 130 still easy so I just stopped and upped the weight
6 X 155 getting there but still felt light
I took a guess because I didn’t want to burn all my energy warming up so I went to 185 and started my 5 X 5
5 X 185 good ATG Squat felt awesome and I was happy
5 X 185 barely made it but all were good form
4 X 170
I dropped the weight because I knew I wouldn’t make another 5 but I couldn’t hold form on the 4th rep I felt my back arch a little to allow my hips to rise enough for me to stand.
My question is : Is this normal for a beginner being that my muscles aren’t conditioned yet? Or did I do too much warm up? I have never been a stamina type, always more strong and fast. I tried to limit rests to 120 seconds. Should I give myself a little more time or is this not something to be concerned with yet since I am just starting?
