Okay I think i understand-you're saying looking back the whole "bulk" and put on weight was done wrong on your part and you like the leansgains concept.
If that's what you are saying, martin merkhans idea has worked for a lot of people- the first few days suck- I tried it for a week, the first 3 days, from 8-2 my mind was on food- I gave it a ahot during the semester, and since I was occupied, wasn't a big deal not to eat till 3pm. I think it helps keep your calorie surplus smaller when you do it to gain size. Also, don't use it to be an excuse to eat lower quality food (ex cookies to get carbs/fats)-especially since guys like you n I aren't blessed with visually pleasing fat storage sites lol
I think Zed can better help you with grip- but I personally bought a heavy gripper (150lb) one. I started using it during my down time as the night is winding down n I'm just watching a show on tv or soemthing.
