First of all, weight lifting DOES NOT stunt your growth. This is a common misconception that should be dispelled. The American Academy of Pediatrics states according to recent studies, "strength training programs do not seem to adversely affect linear growth and do not seem to have any long-term detrimental effect on cardiovascular health" (http://aappolicy.aappublications.org...ics;107/6/1470).

If you are 12 or 13, then I agree, you don't need to lift heavy weights. Because muscles are not fully developed by then, push ups and pull ups will be enough to develop strength. If you are 18 or 19, however, your body is already mature and is ready for heavier weights. Athletes start weight training in freshman year of high school. Obviously, NBA and NFL players aren't exactly short.

Now, I agree that weight lifting is not for everyone; it depends on your goals. If you want to get bigger, you need to go to a gym and lift heavier weights with lower repetitions. This works out your fast twitch muscles, which encourages strength and size. This is known as bulking. If you want to get leaner, you need to work out with lighter weights (or body weight exercises) with higher repetitions. This works out your slow twitch muscles, which encourages definition and endurance. This is known as cutting. Weight lifters usually go through both phases. Bulking and cutting each serve their own purpose and are equally important.

I don't recommend eating chili as part of a person's daily diet. Unless homemade, those canned chilis contain way too much sodium and fat. Eat some tuna, instead.
