The older I get the more I realize if it hurts don't do it. I don't bench with a bar anymore. Just not worth the pain and the resulting damage. I use to press behind the neck for decades. I don't use them now. Tempted to start light and see how it goes but I realize I'm tempting fate.
Regarding hand placement with my shoulders no matter how I do them I have to be careful. Using a narrow V bar for pulldowns seems to be the best option for now. For awhile hands facing lat bar was good but then they hurt too. I used revolving handles that allow the natural path your body wants to go worked for awhile. Now I am using the cheat machine to build up strength. I have twice severely hurt my shoulders from pull ups. Don't understand the mechanism behind it. Doctor told me I have a slap tear in both shoulders but it's in the best possible spot. (?) He recommended no surgery and also said what happened is that I also sprained my shoulder like someone can sprain an ankle. It blows up and is painful but it will get better and it did to an extent.
I would just avoid dips. We all have exercises that have been really productive through our training career but when it starts to hurt a joint just give it up. Try to substitute something like close grip bench. You might want to consult an orthopedic surgeon to make you don't have a tear. Try to see a surgeon that specializes in below the shoulder. A tendon could be partially torn. Cartilage could be torn. He will order an MRI. It could be painful tendinitis. As hard as it sounds and I should talk (sarcasm) use a lower weight and slow rep cadence.
As you can see I don't have any answers. I find my self going from one injury to the next. My wife says, " Don't you understand you're not a kid anymore?" I really do push it. Today I trained delts and arms. Then I went for a 2 mile run. I feel really burned out and exhausted. Think I'm going to a Yates week where I train each body part once a week and one work set per exercise for a change week.
What's your thoughts Scott?
(On a complete side note I don't use the smith machine. In my gym I see guys using really heavy weights on it. For example saw a 60 something guy using what appeared to be 140lbs in smooth slow press behind the neck on it. Curious about it I lifted the empty bar today and it turns out it's counter balanced. The empty bar weighs about five pounds. So one 45lbs on each side of the bar would be about 95lbs. Mystery solved, lol.)
I have to use the Smith Machine and I figure it's probably half the weight I put on there. I train in a Mentzer style but tailored to fit me. Some days I can go "heavy" (relative to my wimpiness!) and others I will do sets of up to five sets of 20 with whatever weight I can do them with and still other days I will start with a weight and do as many reps as I can for 3 or 4 sets.
I really have to warm up my elbows and shoulders. Dammit!
I am somewhat handicapped from a fall so I can no longer do squats or any real leg work unless I just want to do one leg. I have both of them but one is like the small fiddler crab claw now, LOL!. Too bad as the squat was my favorite exercise bar none.
Right now I do chest, shoulders and triceps one day and back, biceps, forearms and abs the next then rest a day and repeat. Total sets can be up to 9 but that includes my need for warm up sets. I'm in my 60s and just cannot take the punishment anymore. I do not recover as I did 40 years ago. I bought and tried Mentzers book on training every 7 to 10 or so days but that stuff is HARD and I could not get anywhere in terms of muscle and strength gains. The 4 count on positive/negative reps is one of the weirdest things I have tried in my over 4 decades of training. At first it seemed good, but nothing much came of it.
On a positive note, training has been worth it, even if I am not as well built as many here I am still better off than many high school kids I see. Fat, skinny-fat and worse, kids today have nose in their phone. I cannot begin to fathom how someone like Arnold or Franco must feel. It is frustrating to age but it is what happens to all of us.
It sucks big time, dammit!
I am going to try some of the Mentzer type routines I've read here and will make them fit my ability. Or lack thereof.
