Honestly 20min workouts are indicative of a lack of effort to create the necessary stress to make any change
You are headed to the "i worked out for 3 years straight and here's a before and after that look identical" results
If starting with the bar is where you need to start, fine, but add weight and volume as necessary or you will not change anything
You have to cause enough stress to disrupt homeostasis then eat and sleep enough to recover from it to elicit an adaptation of strength, size or both
It should be difficult, if it's not then that's a big red flag
