Yep...these types of routines have people mistakenly thinking they are working out "hard". They say it is "intense". But it is percieved effort and would be more "intensiveness" than intense. Your workouts are colored by fatigue. You don't you workouts to be based on perception but on actual iron
And three times a week? No way you can be working very hard...it just feels hard.
If you look at what you body is like now, with the lower body needing to "catch" up then that is the proof of the adage "form follows function" if anything is.
You don't necessarily have to drop everything..it depends on your goals, etc...but basically you should listen to what Kane is saying. Quality over quantity.
