Exersice routines anyone?? :)

@zulega

What do you want to achieve?

At home or at the gym?

I don't think you should run 3 hrs/wk. Since you weigh so much it'll be extra hard on your knees. If I were you, I'd get my weight down by about 60 lbs before doing anything high impact i.e running. You could go for a walk for a hour instead, increasing your speed as you get more comfortable with the pace.
Since you like the biggest loser, you'd probably like a group environment with an instructor motivating you to keep going. Most gyms have different types, for various fitness levels, so try them out!

& you can probably get away with losing 3 lbs a week, since you have quite a bit to lose. Don't expect results like on the shows though and don't aim for them, the ppl on there are monitored by doctors etc.

At first you can lose quickly, but it should slow down IF you want to keep your muscle mass (you do) and sustain your loss (you do, right?). Losing muscle is inevitable but you want to keep as much as possible since muscle metabolizes calories. Fat does nothing for you. Your goal is to lose a high proportion of fat.

Also, IMHO if you push yourself that hard, you will almost certainly injure yourself and theoretically shoot yourself in the foot. Please research weight lifting, and balance cardio with lifting. I have learned the hard way, and I lift much more than I do cardio. I can tell you I have been a yoyo dieter since I was 14 YEARS OLD, and never again will I go back.

Also, find a BMR/calorie calculator such as IIYFM or fitness frog.com and use it to set your calories, 1200 IS TOO LOW. Not sure what you set at, but that seems to be the default calories set by MFP for women, and you may lose fast at first but again, it's not enough and your body WILL get what it needs from your muscles, which again in the end is counterproductive.

I apologize if I sound bossy and like a know-it-all, but please read this from the perspective of a 40's something woman who has lost weight and regained it multiple times. Now I am sooo happy b/c what I am doing is WORKING. Just wanted to share with you. Take from my advice and experience what you want...or leave it....

And oh yes, I do the following:
2 days cardio (50-60 min)
1 day hot yoga (good for flexibility)
3 days of lifting (strong lifts 2 days and I just started 1 day of kettlebells)

Sometimes I take 2 rest days and only do 1 day of cardio. If I do that I add HIIT training to the end of a lifting session.

Good luck!!

If you are willing to take the time and go through my workout, you can check them on Fitocracy.com - username: matuskap. I log every workout for 2 years i think. Maybe it will help you.
