I apologise that this is not directly a paleo diet question but maybe someone can point me in the right direction and or to a better resource.
I currently workout on my own: body-weight + free-weight (dumbbell/sandbag/kettlebell) workouts (mainly HITT), not at any gym but hoping to join a crossfit gym next year.
My problem is that over the year I have developed poor technique in my general lifting and I am really trying to fix it before I increase my lifting weight. The issue is that my left shoulder is much stronger than my left arm and so almost always engages in lifting the weight first. The issue is noticeable even after sets of push-ups and pull-ups with much of the muscle "bulk" in the left shoulder and right arm.
In the last month I have tried to isolate my left arm bicep/tricep by lowering my dumbbell weight and focusing on slow controlled reps, and I have also started using a mirror whenever I can to keep myself in check.
I would love some specific technique guidance to fix this issue. If anyone could help I would greatly appreciate it.
