I have a big discrepancy in shoulder strength. My question to you is to try to strengthen the weaker shoulder most effectively, do you suggest using dumbbells of different weights [one lighter, one heavier] when doing shoulder presses, using dumbbells of the same weight but just continuing on to failure with the strong side after the weak shoulder has failed, or doing more sets with the weak shoulder than the strong one?
Not an uncommon problem. Our bodies are often out of whack from habits or injuries from years ago. A kid might be shy and minimize his or her stature by slouching or rounding their shoulders. He or she grows up with shortened muscle structure here and lengthened muscle there. A minor injury, badly sprained ankle or such, causes the body to compensate and one develops muscle imbalances. Sit in front of a computer for lengths of time, and, oops, we’ve got a pretzel. Most everyone is a victim.
Treatments of Rolfing and/or Feldenkrais (wonderful stuff) can restore or awaken neural pathways that have lost their way and bring health back to the system… just a thought.
I don’t use different weights or rep patterns to overcome a common or typical muscle imbalance. I have the stronger-left-shoulder, weaker-right-shoulder scenario. I treat both the good and its lagging partner as one. I choose the lighter weight and proceed to train with focus and form. If the matter is severe — arm in cast — I engage in emergency tactics. That’s another story.
If you have a significantly injured left or right region — biceps, knee, shoulder strain or soreness– then the use of dumbbells is wise. The injured area requires its own therapy, with attention to groove, range of motion, hand-position and weight, usually guided by pain and common sense.
That’s all… Go… Godspeed… Dave
