Just put in the work. When you start feeling the pain or anxiety make sure you take deep breathes. The mind wants you to quit when the weight starts to feel heavy. Our bodies have a fight or flight response but if we breathe properly we will be able to think and react more clearly. If you want to get better you have to show up and do the same boring work. It's not pretty but the results will come. Here I do 220 lb squat x 10. Road to 315 lb squat at 155 lb bodyweight.
