Here's my story. I am 14 y.o., about 5'7", 145lbs. @ 13% BF. =\ I have no access to a gym, nor equipment beside a chin-up bar. My goal is to have a fit body. Not too buff, but like an athletic build. Does anyone have a fullbody workout routine? I was thinking I would do like Monday, Wednesday, and Friday and rest Tuesday, Thursday and Saturday. Since it's summer, I have time on my hands. But near end July, I have an operation and will have to stay in bed for two weeks. Also, I don't know if this is important to my routine, but I have something called Precatious Puberty. (Runs in the family) P.P. is that my body is growing faster then intended. I am 14, but my body thinks it's 16. So to slow down my growth spurt, I'm taking injections every month for 2 years. 1 more year to go still. Please help. Thank you in advance!

Not sure about the PP, or the effect that the injections would have on your ability to grow and perform. So let me make a blanket statement that what you read below is for a healthy individual of your age, or an individual otherwise healthy who has received clearance from their physician:

There is plenty you can do without any weight at all.
1. Pullups
2. Chinups (With your palms facing you)
3. Pushups
4. Lunges
5. Jump Squats
6. Jump Lunges
7. Speed Squats
8. Crunches
9. Bicycles
10. Leg raises/flutter kicks
11. Mountain Climbers
12. Squat Thrusts.

Those are just a few of the many activities that you need only a pullup bar and the ground for.

Now, if you run out to Target or Wal-Mart and pick up a set of adjustable dumbbells (they usually come in 5 - 20 pound ranges) and a maybe a blowup exercise ball then you can do even more.

Why would you want to slow down puberty if you're planning on getting fit anyway? Puberty at the same time as lifting was excellent timing for me to make huge improvements. This was abot a year ago but I began lifting slightly before puberty, and I could only do 95 pounds for a 10 rep on the bench press (even though I had already been lifting for a while), I had a growth spurt and in the time of 1 month I could do 135 for a 10 rep. That was a while ago, and unfortunately broken thumb and tendonitis screwed me over afterwards.

but anyway, on to your questions

To start out for getting buff. Yo might want to try doing crunches for 30 seconds, then immediately do bicycle kicks for 30 seconds, and then immediately do 15 pushups. Take a break for about a minute and repeat. As you get better you can increase reps, decrease break, whatever. For legs you can do some of the lunges that adler suggested as well as wallsits.

I would really recommend getting adjustable dumbbells to use. Powerblocks can be adjusted to be from 5 pounds to 45 pounds in 5 pound increments. They aren't too expensive and you can use that kind of weight for a long time at your age. (I'm almost 16 and I've had a good pair of dumbbells I've been suing for a long time) Also an incline decline bench (these can come cheap) will be quite helpful.

Thank you very much for your guys' advice! I'll stick with the crunches, bike kicks and pushups and probably mix in chinups until I can get some dumbbells. Reps for the both of you! BTW what are bike kicks?

What's the diff between pullups and chinups?

NVM found out how to do bike kicks.

Not sure abo the difference between pullups and chinups. I don't do them very much except for a test every once in a while.

Oh, ok. Thank you very much for your help. =)

You're welcome.

Oh btw. don't eat junk food.

I'll try not to. Lol. JK.

Oh, and the crunches/bike kicks/pushups/rest routine, should I do that everyday?

WEll, you'll be sore after the first time you do it. Mix it in with some cardio I guess so every other day should be good for a while.

The thing is, thats more of a getting ready to lift weights kind of thing. I don't think you'd see drastic results from continuing thar program. I'd get some dumbbells and an incline decline bench if I were you. You could go to walmart get a good set of dumbbells and a good bench (you might have to go to the online store) for about 80-90 bucks cheapest. and that bench is always helpful and if those dumbbells go from 5 - 45 pounds you could use those for all they're worth.

Why not use your school gym? Or tell your parents to pick you up a starter weight kit from Target or Sports Authority. Or try to find something used, craigslist.org

My school that I just graduated from doesn't have a gym. But the high school that I'm going to does.

Since my high school has a gym, I could continue this for now and when I go to school, I can use the gym. =)
