Suggested workout regimen for a lanky teenage guy?

I'm a girl but I'm at the gym a lot and from my perspective and from the guys I know, what you need to be doing is maximum weight training and minimum cardio. An ideal workout would be a 10 minute run to warmup then hit the weights hardcore. You want heavier weight with smaller reps to bulk up and right after your workout go home at eat protein to help rebuild the muscle you've been working on. Cardio gets your heart rate up and if you stick with it too long you'll end up burning more calories and losing weight, which with your height I don't think you want to do. Just maximize your efforts with the weight training and remember the PROTEIN. Also, if you go to a gym ask the staff or a personal trainer for some input, they should be able to give you some solid advice. Good luck! :)

Eat a lot. Somewhat healthy, but eat a lot. You're going to be building a lot of muscle and that muscle needs fuel to grow on so you can NOT be malnourished.

Keep up the running, and perhaps join a gym. Try to go to said gym three days a week and use the weights to exercise your arms, shoulders, back, chest, and midsection.

Of course, results will not be instant. But after many months of this, you will see yourself become more musclar and better looking.

Eat lots of protein and lift some weights. The scoliosis may hinder extremely heavy lifting, but weights will strenthen your muscles and add some bulk to you!

Stay away from healthy food... its a scam.. eat whatever you feel like... drink whatever you want...

go to the gym twice a day and cross train , lift weights, i know... join the marines, bootcamp is great! Fun too!

Swim, bike, race motorcycles, hunt, ski, skydive, run marathons, dig for gold, play the banjo, shoot pornos, run from the cops, go wild,,, use your imagination,,,

and whatever you do dont trust in santa to bring you what you asked for.

need to eat healthy and use the right type of exercises. Suggest to start with interval training and body weight exercises.

I agree with Tony V 100% except for one point: DO NOT DO CARDIO! You have no fat to you, why would you waste time burning the little fat you have? It makes no sense. You need to spend all of your exercising time lifting weights.

im 15 and im like 5,7 133 pounds what you gotta do is work on your upper body like push ups and chrunchs if you want to get bigger you need to eat more as you convert it into muscle. that will make it so you have more muscle

hope this hopes {:
