Bit of a problem, requesting help. Please read.

The way you are feeling and what your body is doing sound like what I went through, once upon a time. I was trying desperately to get down to what the height-weight charts (and my doctor, who didn't look at the actual patient) said I should weigh and get rid of that tiny tummy bulge... and had managed to get my body fat down well into the single digits. (Not good.) I applied for a medical study that needed healthy obese-according-to-BMI controls, and was turned down because, though I fit the criteria, I "wasn't overweight" -- really bad science, but also, you'd think I would have listened.

Friends told me I didn't need to lose any more weight -- I thought they were just being kind. Strangers stopped me to ask how long I had been a body-builder -- I thought they were strange. I sank in salt water -- this should have been a clue!

I was tired and achy all the time. My periods stopped. I started passing out -- and finally, finally, re-evaluated my goals.

I am glad you're not making yourself as sick as I did, before taking a hard look at what you are doing. You seem to be eating pretty well, what you're eating, but it may not be enough.

1,200 calories is not a magic number. Every body is different. This is not medical advice. Et cetera. But you sound like someone who has a serious metabolic problem.

Even if the main problem isn't too few xalories but something else, overstressing your body by trying to lose more weight right now.may be a bad idea. Presumably, your doctor has checked you for mono and maybe Lyme. Probably, the expert you might be seeing will look at thyroid and adrenal function. Maybe nutritional deficiencies are causing part of the problem -- a good sports nutritionist might be able to help you a lot.

But really, if I were you, the first thing I would try is eating more. Maybe taking a good stress vitamin. Maybe taking a week off from exercising. Then forget losing more weight right now; work on building muscle, if you want, but those extra pounds you want to lose may be a bad idea, and some of the sagging may just be because you're unwell.

Good luck -- hope you feel better soon!

Get heavier weights. 15lbs isn't going to cut it - get a bar set. Then get a book like Starting Strength or New Rules of Lifting for Women and follow that program. That'll get you where you want to be a lot faster.

I have one more question.

Do I have to do a lot (if any) cardio exercising (besides walking the dog) to get toned?
I mean, if I just do be fit in 90 (which has both cardio and strength) will I see toning? Do I have to be sweating profusely, and feeling like I am going to die, to actually be doing SOMETHING?

You do not have to do any cardio to get 'toned'. A low enough BF and strength training will do that. I would do an actual strength training program and not the DVD.

ETA: I would like to emphasise that your BF may well be low enough/too low but you are lacking LBM.

Also, you may have missed the question, but what did your doctor say when you saw them a few weeks ago? You appear to be worrying about the wrong things here - you have missed 5 periods which indicates some type of possible issue - which may well be caused by diet/exercise etc.

Does anybody know any ROUTINES for toning with body weight and dumbbells? Preferably on you tube? I know a lot of different exercises, but no routines.

Go get a kettlebell, they aren't very expensive, and google kettlebell exercises.....I think that will really help.

The thing is, I would like full routines, so I know I am not missing anything...

You can get a long way with one 15lbs/20lbs kettlebell and a $10 dvd like Angie Miller's kettlebell bootcamp - lots of levels to do... EAT more, are you trying to starve youself ? Your body cannot do all the exercise and stay healthy on no fuel....
If you want to combine strengh (for "toning") and cardio, the kettlebell will be your best friend......

How are you going to fix your diet first? Because you can't sustain the workouts until you fix the food.

And yes, what did the doctor say?

Stop excercising for 1.5 hours a day - 30 minutes or so should be enough - it is best for fat burn.

Add weight training about 2 times a week min - this helps tone lift and keep lean muscle mass

Eat more... I think you are eating to few calories a day add some more protein

Rest one day a week - no exercise at all you need to recover too

Do you ever want to be healthy? Do you ever want to have children? You may be wrecking the possibility of ever having children, and always having messed up hormones, unless you eat. You can always fix fat. I'm almost 50 and I am fixing my fat. Fix your health.

Stupid question, do I HAVE to lift heavy to get toned? Or can I eventually achieve that with only body weight and dumbbell exercises? And by upping my calories. I don't have access to heavy weights, and I might not for quite a while. (If I ever do, will 30 minutes every other day be good? I am hoping to sometime in the future (a year or two) to get a gym membership and a personal trainer but it could be a while till this happens) Also, If I decide to take a week long break from hardly ANY exercise, and up my calories to 1400 a day, will I turn into a giant ball of fat and skin? Or will that only happen if I eat over?

1400 will not likely be enough calories to correct your hormonal imbalance. It's very likely that you'll need to eat more than that and I'd take a full week off of exercise. 1400 will likely be a deficit, you need to eat at least at TDEE.

Late the game in regards to routines, but both are full body workouts without any equipment required:
