Goosey.
yes, intensity is hardly enjoyable.
What i was referring to is comfort with certain exercises. For example, I have always hated bent over rows and T-bars as always felt too much to do. Always preferred machine rows and pulldowns to really isolate and contract back muscles.
Same with leg press; do not feel comfortable, especially as I choose to focus on unilateral methods to try and regain balance since serious stress fracture.
I also feel that some exercises still compound, say lunges and stepups, and do not have flexibility to do squats properly.
That is what I refer to when I suggest finding right exercises to suit mindset.
Yes, intensity, a necessary requirement depending on your ability to recover in terms of frequency, is always painful.
