So I'm looking to revamp my workout routine, or use one from this site (probably that one). Right now my routine is very basic, on back / bicep days I do some back and bicep stuff, leg days I do leg stuff, etc. There isn't much thought or structure to my workouts other than they fall into that muscle group so I'll do it. I've been doing this for about 4 months and its gotten me decent gains so far, I'm sure a lot of that is because I wasn't working out at all for a while before those 4 months, but I feel like this won't do as much for me long term and I will more than likely plateau (if I haven't already). I'm looking for the best workout that is going to help me get rid of the bit of pudge I have left while either gaining strength or gaining size, which ever one will be best for the situation. Right now I'm 5'9, 175-178 lbs, 250 bench, 315 deadlift, haven't maxed squat because my back, I use 40 lbs dumbells for sets of 6 for bicep curls, if any of those numbers help. Thanks in advance for anyone who decides to pitch in some advice!
tl;dr Need help with new routine for light pudgeloss / muscle gain
