Those aren't pathetic weights! I'm on week 4 and that is about what I am lifting BUT I worked up to that AND I don't have to take a break. Do whatever weight you can do to finish all the reps and be tired on the last rep.

Those aren't pathetic at all! And you will make gains no problem, I'm sure. Just give it time!

I'm 5 foot...135.

i just finished my first week and we are lifting about the same. i do a bit more for lunges and stepups. what i've been doing is increasing in 5 lb increments as i can. if i get to a weight that i couldn't do the full 15 for then i stick to that weight until i can do the full 15. that's only been an issue for seated rows. somehow i jumped from 40 to 60lb b/c i didn't know how to read the stupid weights lol they left the zeros off of all of the number so i thought it was maybe 6 kgs which i figured couldn't be too bad.

i plan on pushing myself just a little more each time. i'm so excited about this but i don't want to hurt myself.

i'm 5'2 as well.
