Both ways to stretching require daily dedication and awareness. Dedication in 5 minute increments and awareness that you are actively doing something.
Stretching whether passively (yummy feeling) or actively (engaging and fatiguing muscles into submission) requires your participation!  

You must think about what you’re stretching. As well, think about what the two end points are…knee and hip for hamstring or quad stretch? Elbow and shoulder for tricep or lats.

Mind you, this will require you to learn your muscles. At the very least, the bigger ones.  This is your only body. You get only one! Learn it, appreciate it, love it. 
In return, it’ll make you feel so good!!
