I've noticed that in trying to make gains by going high weight, low reps and incresing weekly when possible, that my form is a bit shaky on my max, that is I tremble a bit and rock a bit-nothing out of control, but definately noticable. Is this ok? If not, how is it possible to increase and max out without straining some and your form paying the price. Some yahoo at the gym who thinks making gains means high reps, commented to me that my form was off and I should lower my weight like him. Is this legit??
