I have been lifting seriously for about four months now, and I have noticed that when I work my pecs my right pec never does any work. I have tried everything I can think of to fix the problem but nothing helps. Every chest exercise has the same results. I notice that the next day my left pec is sore but my right one is not. Now my left pec is bigger than my right! I tried using lowering the weight to ensure proper form but it doesn't help. Any ideas would be greatly appreciated. Thanks.
