No dis but; Matarazzo & De Mayo...you must mean decades since being in a gym. De Mayo, an all time classic BB'er in my view.
Your probably in the late 30's /early 40's (or older) so might want to pace yourself slowly when returning to the gym. I am acquainted with working with trainee's in their mid-40's to late 60's. All seem to make progress and reach positive goals, though it may take a bit longer. Recovery and the CNS is one of the major keys.
Another important point is that, don't let your ego get in the way of common sense. Suggest doing a full body workout (as Wooo suggest) for the first 3-4 month or so. Than branch out to splits or more advanced forms of training, to see what they offer, if you wish. Might surprise yourself and fine that full body workouts are all you really need.
Basic full body...First week only train twice a week. From the second week on, train 3 times a week. Try not using machines, but the standard BB/DB's. Will find that the whole body can reach a better state of condition with free weights...as of now. Rep range 8-12 for all exercises. 2 sets the first two weeks..than 3 sets after that..no more for now.
!) Squats...not your favorite, than do BB Hack squats which is more like a combo squat/reverse DL. Forget about doing machine leg press. BB Hacks, Like DL's, also build back & trap mass. Try having the heels on a 2X4 if trouble with balance, at first.
2) BB Row or chin
3) Bench BB or DB
4) Overhead press
6) Tricep Dips
7) BB Curl
If wanting to do the Abs, than 2 sets before starting the legs work. And 2 set after calves. Still with the 8-12 reps range. Add weight when 12 reps are reached. Abs should be treated like any other body part. Good Luck.
