im more referring to the people who look like they are having a mild seizure. not just have their back slightly or mildly elevated. swinging or erratic rocking of your body while curling is horrible as well. some of the points im referring to. most ppl who arch their back also raise one shoulder slightly off the bench as well in my expierence so (were not talking about people that know what their doing or this post wouldnt exist =) ) ... thats more what im referring to. now touch on it! im more saying this for ppl who are slightly new to the whole hard core lifting thing. even for casual lifters. form is always important far more than weight/reps/sets. drop any or all to achieve the best form you can manage. anyways .... GO.. no more stall tactics you write!
