Can anyone give me a 16 Y/o Male workout for abs and a lean body which is possible in 9 weeks? I can jumprope, treadmill, or homeworkout?

Go to FitnessBlender and join. It's free. It has a searchable database of workouts with how-to videos. Search for something like cardio without equipment or strength training without equipment. In fact, do both. And then alternate your workouts. They even have some workouts you wouldn't normally think of, like quiet workouts. In case you don't want to wake people up. There are also meal plans so you can learn to eat healthily.

Fitness blender has started charging for things. But there are still a lot of free things. But the prices are pretty reasonable. Oh, and check out their YouTube channel. The searching isn’t as convenient but you can still find a lot of different types of workouts.

If you find the site too overwhelming in their choices, maybe the best and shortest home workout is the "Scientific 7 Minute" workout.

Go ahead and just google it. You will find a pdf with directions, youtube videos, and even apps. Below, I’ve provided you with a link to my favorite youtube video at the bottom. This is a lot harder than it looks. But if you think its too easy — do it twice. If it’s too hard, and you can’t finish, that’s OK, just try again in a few days.

Another suggestion is the “Men’s Health 3 Moves 300 Muscles Workout”. It's a 15-minute workout. Again I’ve given you a link to a youtube video.

And there is a new one called the Nine-Minute Workout. No YouTube video yet. but here is the directions

You can just do one of these till you get bored and then switch to another one. Or alternate them. By the time you are bored with them all it will be time to do something even more challenging.

That's only a bit more than 2 months. This is enough time to develop strength and tone, but not a lot to develop definition. Count on 6 months to really develop definition.

And, you can't target weight loss. Fat deposition is governed by genes - some people gain weight in the abdomen first, some in the butt first, some in the legs first, etc. But jumping rope will help you lose weight all over.

Do 55 sit-ups everyday.

Drink water and water only for atleast 5 weeks.

Eat all your food on your plate.

Run the treadmill for 3.5 a mile twice a day and you should be good.

Lift some weights, that's your choice.

This is my workout regimen and i'm only 13 and I currently have a 6 pack that can be seen through tight shirts as well.
