So far ive seen a bunch of posts about lifting etc. found my way to mehdis "program" its got some criticism but for the most part I can do it, but i've never lifted shit in my life and i'm not sure where to draw the line with pain etc. but at 5'9 and 175 pounds, i've been following this sheet and Im sore every day (3 days in), is it me just being a little bitch or should I actually be worried?
