Maybe I am just paranoid, but I feel like in the past 2-3 months I have been going to the gym on a regular basis, certain exercises seem more awkward for me to perform. For example, on the triceps extension machine, my arms bow out instead of staying inline, and when i take a barbell and raise it to my chin for traps, its very awkward for me no matter what the weight. There are other examples, but all similar to that scenario. I keep questioning myself whether Im not doing the exercise properly, or maybe certain things just arent working for me. Sorry if this seems like a stupid question.
