When I work out for each body party I usually do something like 12/10/10/8 or 12/10/8/6 depending on how I feel. Is this a good amount of sets and reps to get stronger and bigger? I usually do 4-5 exercises for each body part as well. Also when I do flat bench I do a chart that goes like this 12/10/8/6/4/2/8. Any suggestions or opinions? Thanks.
