Aerobic stamina while gaining weight

walking>running but sprints>walking, if you wanna stay in condition just do a sprint workout or 2 during the week, it will also add muscle

Sprints don't work the right energy system for stamina. Walking or jogging does.

really?! go run a 200 yard sprint or a 400 and then tell me if you think differently, sprints put everything else to shame and is much better for your health, body, and joints

Oh ... yeah, I must of missed that. I didn't realize you were talking bro science. My bad. Keep spouting off ignorant bullshit.

Sprinting a 200 or 400 yard (my guess is you mean meters seeing as they are standard track events) focuses on the ATP -PCr and anaerobic glycolytic systems that are only able to maintain dominance over energy contribution for 10ish and 180 seconds respectively. That does not sound like stamina too me. It sounds like a short bursts.

And give me some evidence that sprints are healthier for your body. The higher impact sprints puts the knees at MORE (does not mean you should not run) risk of injury than low impact walking. On top of that aerobic activity at the lower intensities is much more beneficial because it not only causes peripheral adaptions (which sprinting can also cause), but also central adaptations (that sprinting has minimal affect on).
