I have been lifting religiously now for over 9 months. There have been a number of other episodes in my life in which I lifted regularly for a period of months, but this is the longest I have been able to continue without an injury or something else ending it.
For at least the past 4 to 5 months, my incline dumb bell press has not improved at all. I can reliably always press 2 x 80 lbs., but sometimes fail, sometimes succeed with 2 x 85 lbs.
I’ll give some more information below, and would appreciate any advice.
The truly frustrating thing is that I either can do at least 10 reps with 2 x 85 lbs., or fail getting the first rep up. Once both dumb bells get past a certain point, performing another 10+ reps is simple.
The problem seems to be getting both dumb bells from the tops of my thighs / knees to the point the tip of my elbow and shoulder form a straight line (or another way of saying this is the point at which my upper and lower arm are bent at a 90 degree angle). It seems a balance and stability issue, and a weakness issue at certain points of the initial lift. Sometimes one dumb bell or the other will fly out at an angle (painful and frightening with heavy weights), or I succeed with one dumb bell but not the other. Or I simply succeed with both.
I do not have this issue with the dumb bell flat press, or the dumb bell military press. It’s the angle that gets me on that first rep for the incline bench press.
If I have a spotter to help with the first rep, I can use up to 2 x 100 lbs., something I did 5 months ago. I currently do not have a training partner, and cannot reliably get a trusted spotter at my gym.
My training regimen is well-rounded. Chest, shoulders, abs, intense cardio Monday; back, tri’s, bi’s, cardio Tuesday; core training (stability, balance, muscular endurance, abs / obliques with lots of Swiss ball/ small exercise ball/ bosu pad / body weight exercises such as push-ups ) and intense cardio Wednesday; chest, bi’s, cardio Thursday; back, shoulders, tri’s, intense cardio Friday; Legs, abs, cardio Saturday; rest Sunday.
Exercise sessions are between 2-4 hours in length 6 days a week. In virtually every lift and exercise besides incline dumb bell press, I have continued making steady improvement.
On the flat bench using a 45 lb. barbell, I rep 275 lbs x 8 for sets. Military press with a 45 lb. barbell and a spotter, 250 lbs. x 4 for one set. Using a dual axis plate loaded bench press, where shoulder stability is not an issue (see below), I have pressed 445 lb. x 3. I can perform 125-136 consecutive push-ups (resting for a few seconds with back arched at progressively shorter intervals after 90 straight), and 32 straight pull-ups with good form palms-in.
I suffered a right shoulder injury of moderate severity about 15 years ago, and at times feel unhealthy pain in my shoulders during certain lifts. For this reason, I have generally avoided dropping my elbow below the tip of my shoulder blade when performing presses (bench, military, etc.).
Two protein shakes daily, plus a host of other supplements.
