Deadlifts and squats are very effective in building size, strength and thickness in the legs, hams, lower back and traps but it takes a lot out of you and most of you guys are very lazy, you would prefer to sit on a machine and push out a few reps then check social media on your phone, now the fox and sour grapes mentality comes in, because you are too lazy to do it you bash the exercise so you can feel better about being a pussy.
