It is perfectly normal for one arm to be stronger than the other, its very common for personal training clients to find one arm gives in quicker and it is certainly nothing to cause concern. YO may want to follow the next few tips to help get that weaker arm up to speed
If one side is stronger than the other, that stronger side will nearly always take over during an exercise where both sides are being worked together, for example, a press up. If your right arm is stronger than your left, your right arm will always do more work and you probably won’t even notice it, it just happens. Your nervous system won’t allow the overloading of a weak link and, as such, even a slight strength disparity can prevent optimal muscle growth and strength gains
1) Switch to unilateral exercises
There’s a good reason why you have a muscle on one side that is bigger or stronger than the other side. Even if you haven’t noticed, it’s the side you have been using most often in your everyday tasks. It’s the side you automatically use when you need to hold, carry, move, lift, open or close something. And during your workouts, it’s the side that does most of the work. The way around this is to change your bilateral exercises (both sides are used at the same time, like a barbell military press), with unilateral exercises (both sides are used individually, like a dumbbell shoulder press.)
2) Use your weakest side first
You are at your strongest and freshest with whatever side you use first, and you are at least slightly more tired with the side you use second. Therefore, whenever you do an exercise where you train each side individually, always start with your weaker side
3) Let the weaker side determine the workout.
Let your weaker side dictate what you allow your stronger side to do. So, if you can only do 12 reps with your weaker side, then you should only do 12 reps with your stronger side… even if you could have done more. This will give your weaker side a chance to catch up to your strong side, then allowing both sides to progress equally from that point on.
4) Make sure there isn’t an underlying problem.
In many cases, people just have a dominant, stronger side that just ends up doing more of the work in the gym and in everyday life in general. As a result, muscle strength and size imbalances are created over time. If not there may be an underlying issue at play that not only cause these muscle imbalances in the first place, but prevent them from being corrected. If no improvement is seen then further investigation will be needed.
