Never once in my life (even when I was just starting lifting in the 6th grade and had no idea what to do) did I bench 3x a week. I really don't think that will get you anywhere. I don't know about the running. Some people get shin splints pretty easily. It's really up to how you feel. I think polished answered all your questions in great detail and I would definitely take his advice on all 4 answers.
How do you figure if you're doing a full body routine... You're suppose to workout your whole body 3 days a week (AxAxAxx). Which would mean your chest being worked out 3 days a week. The only lifts you don't do 3 times a week is squats and deadlifts. Squat twice a week and deadlift once a week. Just like wolf says for these routines...
Weightlifting option 1 - AXAXAXX
- only one workout, done thrice a week on non-consecutive days
- doesn't utilize supersets as it's meant for beginners
- tempo isn't listed as beginners should focus on getting the form down (explosive positive and controlled negative)
- all rep ranges are lower to allow for form learning
Workout A
A Squats or Deadlifts - w 5x5 / 180 -squat twice a week, and deadlift once
B Bench press - 3x5-8 / 90
C Bent-over BB rows - 3x5-8 / 90
D Chinups - 3x5-8 / 60
E Dips - 3x5-8 / 60
F Military press - 2x5-8 / 60
E Hanging leg raises - 2x8-15 / 60

Advanced bodyweight routine
- also my ideal vision of a teen workout
- once you can do more than 20 reps on all exercises, you can add some weight (backpacks, belts, and similar)
- also to be done as a circuit, thrice a week on non-consecutive days
- for non-teens who wish to utilize this, superset exercises (don't do them as a circuit), up the rest times to 60 sec and do 3 sets of 8 to 12 reps
Workout
A1 Pistol squats - 2-3x10-20 / 45
A2 Dips - 2-3x10-20 / 45
A3 Chinups - 2-3x10-20 / 45
A4 Pushups - 2-3x10-20 / 45 -work your way up to a handstand pushup
A5 Inverted rows - 2-3x10-20 / 45
A6 Hanging leg raises - 2-3x10-20 / 45 -work your way up to a full hanging V-up
