I have never been obese but definitely have ranged from 10% to maybe 30% body fat at different times of my life.

I'm 40, I have tracked my macros and following all the dieting principles you preach for over an year.

In this period I dieted down twice and I had no problems losing 0.5 - 1 lbs per week during my cuts but at one point I just feel like I'm losing weight but my belly isn't shrinking at the same speed. Not talking about extra skin, just fat.

I wonder if being 40 and have been at 30% at same point of my life for some time makes it impossible for me to get shredded.

Thanks! Your videos are great!

Is it important to take each set to failure, or just the last set? Also, is it beneficial to only go to failure on some days and stop 1-2 reps shy on others?
