You can have a solid training program on paper, but if you don't train intensely nothing else matters.
I actually think that intensity is more important than what you are actually doing as long as some common sense is applied to your training.
The average gym goer is pussy footing their training and the results show. I get annoyed when friends ask to work out with me and they don't bring anything to the table and cry about results.
Why am I following your training program and not getting the results you have? That's a question that they ask and intensity is the answer.
What are your thoughts on intensity? How important is it to you? What has helped you amp up your workouts?
My training revoles around three words:
Dedication. Progress. Intensity.
