You're probably talking about my workout of old which was a bit of a bodybuilder workout. I think it was a good workout that gave comprehensive coverage of the body, but excessive exercise and time in the gym for what I needed.
After a bad shoulder injury during incline bench press (resultant from boxing and heavy weights) I was forced to rehab and re-introduce one exercise at a time or risk re-injuring and doing no gym at all. It was this process that overcame the OCD I had, not wanting to give up any of the exercises I had been doing and spending 4 times a week in the gym for 1.5 hours a pop, sometimes 2.
Started with squats cause least shoulder involvement. Few weeks later introduced deadlifts as it didn't put a lot of strain on my shoulder either. Having been a couple months since the injury with no upper body exercise, my upper body was losing a fair bit of muscle mass, so a few weeks after introducing deadlifts I give neutral grip pullups a go and found that they didn't aggravate the shoulder too much, just a little soreness. 6 months after the shoulder injury I thought I would give the bench press motion a go - grabbed a 15kg barbell and started pressing very carefully and slowly with a strict powerlifter form that I had not used before and closer grip to protect the shoulders. Also brought the bar right down to the chest and all the way to near lock out. One advantage to injury is the forced opportunity to reset form like this and take solstice from having great form (a great excuse for being weaker in the exercise, as we often don't want to accept the realities of injury making us weak).
The range of motion was a tiny bit tender and I didn't have full flexibility in the right shoulder, but I repeated this process for a couple weeks and it gradually returned. Each bench session I would push it that little bit harder striking the fine line between hurting myself and forcing the injured tissue to re-injure and heal around the movement. When that started feeling good I very progressively added weight, moving up to 20kg bar and then 22.5kg etc. All the way up until where I am now about 2 years later. Shoulder still isn't 100%, it never will be and I'll always have a little pain...but you know what, with new and better form and a gradual build up I made my PB of 127.5kg (280 pounds) a couple months ago; a competition style lift. My old PB pre-injury was 120kg and not touching the chest. So you can come back from those injuries you just need to give the body time and respect to do it's thing, be patient and gently work it through the motions until it's ready.
