You're definitely right about the bicep thing, doing curls with weight that's way too heavy f**** pops shoulders up bad!First thing is to stop the movements that are pissing it off (its usually bicep work and going to failure on any push or pull movement), get ROM back through therapy (deep tissue massage and ART is good if the therapist is versed with working on gym bros / powerlifters and not just granny frozen shoulder). Address the weaknesses through movement exercises that will allow your shoulder to take lifting again (the therapist should be able to get you started with this). If it has not been pushed too far, there is no reason why something like this cannot be mostly resolved in about 8 weeks (where you can start doing gym bro lifts without pissing it off) and with a clear path forward (proper warm up techniques and on and off day movements and home therapy) in 8 weeks. But I have no clue as to how frozen your shoulder is (how bad you let it get) and what else may be wrong underneath it all.
At home options?
Get a therastick and grind away in your armpit, pec minor, along your lat and where your lat and tricep meets. That is basically what a good therapist would do to get most of the ROM back. Use a massage gun every morning on the full pec, along the clavicle, in the arm pit, the bicep, inner elbow, upper forearm, upper trap and neck). For maintenance, I use the therastick about twice a week and the massage about four times a week. I do specific movements about 3 times a week and focus on not pissing it off.
Bent arm wall stretch, regular pec stretch, the list goes on dependent on what the problems are.
If you get a frozen shoulder it does pretty much decide on its own when it will unfreeze, but you can help the process by doing anything that reduces inflammation in the area and the less inflammation you have the more you'll be able to do some light stretching. Once you get into that thawing stage, and you're back to like 80% mobility throwing in some dead hangs will really help. But if you throw the dead hangs in too early it'll make things worse.There are three stages to frozen shoulder - freezing, frozen, and thawing. Nothing will help in the first two stages. Frozen shoulder will take as long as frozen shoulder decides it will take to get back to normal. There is literally nothing you can do to "unfreeze" it, it's not a true injury but the tendons in a constant state of tension. If he's a normally healthy individual 12 to 18 months but if he has underlying health conditions like diabetes then it could be up to 2 years. I've had it in both shoulders, my right shoulder was around 10 months and not horrific. My left shoulder was agonizing, the pain brought me to my knees a couple times. It took over two years to get back to normal. This was before i started working out again so that quite possibly delayed the healing process.
Best bet is to to do shoulder mobility exercises and do weight training as far as ROM allows. No reason to actually go to therapy because there really isn't much they can do until it is in thawing stage. Maybe at first just to get a list of exercises. Once it is in thawing stage then start hitting it with massages and an ART practitioner.
Best of luck to him
When mine was bad, I stopped all pressing and upright rows. I would do the rotator cuff exercises with dumbbells and bands and even that was kind of painful at first, then I just basically started doing a metric f*** ton of side laterals for my shoulder work and regular stretching and some mobility stuff. I bet you it was a solid 6 months before it really started feeling better and I was using healing peptides like bpc and tb500 to reduce the inflammation so even cheating the system it still took me about 6 months. I will say that after that was over they've been pretty good ever since and I'm going on like 2 years with no real issues knock on wood. If you ever followed any of my older logs you would know that I used to have shoulder issues all the time and I just don't have them anymore. I definitely probably got lucky and taking a bunch of healing peptides probably had something to do with it tooGymbro I train with has a frozen shoulder. Was advised12-18 months therapy. Any do it at home options work for you or someone you know? I was thinking deep tissue massage, heat as in sauna, yoga/tai chi, cissus, etc.
