whats wrong with me im so week?nothing at all .you just need to apply a change to your diet and training.firstly you dont need to feel as if you need creatine to bypass a 230 bench you can easily bypass that without any supplements by focusing firstly on the quality and quantity of your protein intake.tins of tuna and chicken are reliable sources try them.when ever i reached a serious sticking point in strength in say the bench etc and knowing that im training right i found that i could generally solve it by upping my protein quality or intake with real food not supplements , it really is that important if you do this naturally and i now bench just over 360 coming from a lower starting point than you.now if you increase your strength with a progresive increase in resistance you will grow, however your genetics will determine by how much.your right in thinking that strength is important in achieving your goals and the quickest way to achieve that is to keep the sets and reps low.maybe three sets per exercise and aprox 6 reps per set,experiment a little . although on reps i often on the bench lift singles and double reps as close to my pb as possible as i find that this is the most efficient way to increase explosive strength in the least amount of time and then i mix that up with maybe several reps for a few sets a little latter.always apply good form and never atempt a pb without a spotter the key here is if you eat right and tweak your training thus making it more productive and stay with it the rewards will follow.depressed , well turn that around by attacking your workouts in a very positive manner and you will grow into a a lobster .good luck.
