I’m just getting back into the gym. My goal is muscle building. I am approx 23 BMI (179cm) 69 kg. I’m an office worker and have little strength to start with. I do run however and can easily do 10km in 50 minutes or 3km in 13 minutes.
I know these excercises  but am keen to slowly learn more:
Cardio- 
Running
Elliptical
Cycling

Gym-
Bicep curl
NAME_1 press
NAME_2-up
Pull-up
Chest machine
Lat pull-down
Tricep pull-down 

Make me an excercise plan for the week. I want to run at least 20km. 

I’m happy for runs to be seperate sessions.

The exercises don’t have to be in this list.
