I had the same pain a few years back. It never went away so I had an MRI which showed a bone spur. I had surgery with 6 weeks of recovery. I was lucky it didn't cause more damage. Get checked out!
Thanks for all the info. Started 5x5 today, didn't think it was that tough until about an hour after I finished. Yeah, it's going to burn. FYI I started with little to no weight. I'm no spring chicken
I seem to get a better workout, plus advice from others. The balance really feels different to me. Doing 30 reps on the machine vs 30 reps with free weights feels like more of a workout.
