I'm currently doing a hypertrophy routine. It calls for 5 sets of 10 for weighted dips. I'm working out with 80lbs. My question is when I'm performing the reps it makes my inner chest (middle of chest) hurt. It almost feels like my sternum is about to rip down the middle. It's not as painfull as it is just a wierd feeling. Anybody else have this issue or does it sound like I'm performing them wrong somehow.
