In terms of training again, this is the way that I did it. I am not advising to do it this way but I found it worked well for me even if it sounds a bit risky lol. I waited about 3 to 4 weeks after I had the injury, then at first I would simply have my empty barbell in the catches and lean 45 degrees into the barbell so I was effectively pressing down onto it at an angle. I would simply start off narrow with my hand spacing then gradually space them apart to a bench press spacing the more I got warmed up and the less tight my chest felt as I went down. I did these for 1 or 2 sessions then progressed to pressing the bar laid on the bench as per usual bench press set up. You will notice there is a distinct tight feeling as you get closer down to your chest with the bar. As it start to get tight I would then go no lower than this height and simply press it back up. Over the coming weeks I would begin putting weight onto the bar and building that up, setting the safety racks at the side so the bar could not lower past a certain point in case the worst happened and it tore again. You can feel where the point is that you should be stopping it at. Each session after I would then lower the safety racks at the side and bring the bar down lower to my chest around an inch each time till eventually I was hitting my chest again and was back to normal. This is very much a go by feeling exercise though and you must make sure you never have any painkillers in you before doing this as you need to be fully aware of where it starts to get tight again. There is no doubt in my mind that it heals up a LOT faster when you train the area and drink a protein shake afterwards rather than just sitting back and waiting for it to heal again. All the time scar tissue is forming also and by training (not excessively) you are keeping it supple and elasticated and not allowing it to form hard tissue that is more prone to tearing again. Just like if you have ever torn a hamstring the idea is to keep stretching and exercising it so it does not form back tightly again.

Sorry to hear this man, I guess its a waiting game then unless you begin the therapy. I think it would be worth pursuing the healing peptides in the meantime as suggested below, anything to get the ball rolling in the healing department. When I have had injuries I have pre occupied myself with trying to get rid of a little of the pain each day just in consuming more collagen peptides, protein, stretching exercises once they give a list to you etc When I did my pec in the first exercise I did was where you lean forward at an angle onto a barbell on a bench rack and push yourself back from it then progress from there. I guess you can only really do this if you have a bench at home tho. Just these little things help blood flow again in the area and really do speed up healing time. Get a spiky massage ball too to roll against the wall on. If you aren't friends with him add T-Raww18 to your contacts as he is going through the same kind of thing too, I think his full tear was in the same area.

It sounds like you could have re-torn the scar tissue that formed from the last injury, scar tissue is not as supple as normal muscle so is more likely to tear again as opposed to normal elasticated muscle. The reason you see these other guy's pecs suddenly shoot up in the videos is because the tendon that attaches the pectoral muscle to the bone has completed torn or ruptured meaning the pec is no longer attached at one side so it is now mainly anchored to the centre of the rib cage and 'pulls inwards. When I did mine all that happened was that it swelled up in the middle upper area which is where I tore it. I got my tear during a midway grind as it was coming back down to rest on the safety arms, I could literally hear the tears through the muscle fibres as it came to rest - sounded like a Zip lol. If the Doctor diagnoses it as a tear I would come off the gear mate and just go onto test. It will take about 8 weeks to heal fully and if you stay on gear it will just make you want to train all the time and raise your BP as you aren't working out. After a week of it happening I found I was still able to do deadlifts and also if you have a Safety Squat bar in your gym you will still be able to do those you should find - all depends on if you feel you can lay off the training for 2 months or if you are still desperate to train in the meantime
