Yeah I'm thinking my form still needs work. I dunno what else I can do though. I even have little notes next to me, and I know how to do the setup, chest out, shoulders back, hips back then stand up with the bar close to you but I still think my back is rounding and I still get people telling me that at the gym.
Feel much better today, just a little tight around the ribs like when I breathe in and out deeply, but nothing like last night!
My possible thoughts are I'm too tired to train... been getting 2/3 hrs a night every night this week, or I'm working my core too much with my extra crunches and increased reps on captains chair. Will cut out the crunches and see how I go.
