re: 65 years old, male weight gain

I’m 66, started lifting a high rep , full body workout in mid-January. I have beefed up pretty good and gotten a lot stronger. All I can tell you is, I eat like a horse everyday and don’t gain any bad weight. Doing this or something similar will help you.
Workout three days a week using the following exercise on weight machines in this order:
-overhead press
-wide grip upright row
-Bench press
-seated rows
-curls and wrist curls
-5 minutes on stairclimber
-leg press
**do each exercise about 60-75 total reps, broken down into sets like this : approximately 30 reps on first set, maybe 20 reps on second set & maybe 20 on third set. Each set is to exhaustion so if you are spent at about 65 or 75 total reps, that’s all that you are trying to do is to burn out on each exercise . Now, rest a minute and move to the next exercise on the list. Note, each set is done to the burn out or if not, then you are kidding yourself. No worries with this about hurting joints either. You will also get all the cardio that you can stand with this.
Hope this helps ??????
