Wondering if this good and if i will see good results or am i overtraining myself?
yes u may have seen it before

your body has to rest at some point.  otherwise you just keep causing trauma to the same fibers over and over.  does your lifts consist mainly of compounds?

No the leg press is not the same as doing squats.

somewaht i do isolated biceps and triceps and bent over rows with Db and rest is compound
