Ok guys I need some feedback and hopefully educated opinions on the following. I will turn 36 this year and want to make sure I am continue to lift the rest of my life. The only MAJOR injury I have sustained was 15 years ago when I tore my pec tendon benching very heavy without proper warmup. Fast forward 15 years later and recently I have had the following happen. Started doing dips daily and exploding out of the hole and pulled a muscle in my left pectoral muscle. I took 3 weeks off and I am now back to training with higher reps and easing back into heavier training. About 3 months ago I was learning the KettleBell Swing and started Extremely light and was going very slow and after only 2 sets pulled a muscle in my back. Needless to say I haven't done those since. All of that being said I started training full body daily about 2 months or more ago and luckily up until the recent pulled muscle my body had never felt better from the daily aches and pains. I also have a desk job which causes me to sit at a computer for 8 hours or daily and I have bad forward head posture most likely from 1) desk job......2) Poor posture (IM working on this).......3)From years of Bro Training back in college when I did WAY more pushing exercises than Pulling = forward rounded shoulders and forward head posture??? So that being said I am going to drop my presses to once a week for maintenance and basically row and do rear delt flys for the next 6 to 8 weeks to hopefully correct this posture issue. Also in REGARDS to heavy training as we get older and IN MY CASE have had a couple of injuries is there a heavy rep range that we should stay away from? I recall reading years ago that if you have torn a pec or any other muscle then DO NOT LIFT below your 6 rep max. I have basically always done that after the pec tear I never lifted more than my 6 rep max. I also have seen DC (dante of doggcrapp) suggest lifters over 35 years old not to go heavier than 10 to 12 rep max due to muscle tears. Is his advice based off b/c its REST PAUSE training or does this go for straight sets also? In other words is REST PAUSE more risky at 6 reps then a normal straight set? Anyway I hope Bryan Haycock as well as Old and Gray and the rest of you guys can chime in and give advice on what science as well as real world observations says about... Whats to heavy of a rep range as we get older? As well as any other advice we should follow as we get older in regards to training volume / frequency and staying healthy and being able to lift healthy the rest of our life.
