What kind of workout should I do to improve strength and stamina?

Question

I'm 16 and kind of skinny. I don't want to do anything that will effect my development/growth.

Answer 1

You can do any exercises that you don't feel strain on your joints. For me, I have weaker shoulder joints so push-ups are a no. Stamina and endurance can be increased by running or jogging.

Do not do sprints to increase stamina! Running long distances works much better.
