I need some workout injury advice. I have been doing the "pec machine" at the gym. 3 reps going facing front at 70 pounds (14 times each) then 55 pounds facing the machine (same amount of reps) Well, for the first time my arms hurt whenever I reach for anything. I haven't used that machine for over a week because of this. I just thought it would go away. What was I doing wrong? Why does it still hurt? When will it go away? I really like doing this machine, and the results it gives me. Thanks for any advice!
