As far as the cardio goes, I'd say go with what you're comfortable with- So long as it's not too much cardio. If you're trying to bulk, keep it to two or three short sessions a week- And no, don't piggy back a cardio session with a lifting session. It's best to do them seperately.
When it comes to progress proof some of us have had, well, there are a lot of people here who have had great gains from Max OT- I hate to post links to my own pics, but I think the size I put on in just nine months proves that the program can and does work.
Here they are. When it comes to the tendon/muscle issue, the best advice is to stop. Don't aggravate the injuries, they'll only get worse and then you won't be lifting anything. Give them a chance to heal instead of trying to work through the pain- It's the smart thing to do.
LOPAS-
I can't do deadlift because i have my lower back injury. My doctor said that i can't even do bodybuilding.
If your doc says don't do it- Don't do it. Get a second and third opinion if you want, but if they all seem to agree that you shouldn't be lifting, don't freakin' lift, for the same reasons I listed above- You could make a bad injury even worse. I know no one likes to be told to stay away from the weights, whether it's just for a short period of healing or if it's for the rest of their life, but always go with professional medical advice- Don't look for alternatives from strangers on the net who might not know what they're talking about. Even if I were a doctor, there'd be no way I could give you a decent medical opinion over the internet.
