anyone worry about changing what seems to be working

No! Don't worry. You may feel like it's not working depending on how much strength training you do, but trust me, you will notice in the way your body changes that it is working. The last couple weeks I haven't lost weight but I've lost inches and people have noticed I look smaller so I know what I'm doing is working. I'd rather be muscular and toned while weighing 160 lbs then 150 lbs and flabby with no muscle. I hope that makes sense.

Go to a craft store and get a tape measurer for $2-4 and measure TODAY. Measure when you weigh: before you eat or drink, after you use the bathroom, naked. Measure the smallest part of your waist, the biggest part of your bum and around (hips), each arm right up to your armpit (usually the widest part), and same with your thighs, all the way up to your crotch. You can also measure your chest ('round the biggest part) and then measure again in a few weeks to compare. This really helps!

Strength training has so many benefits for you, it helps you speed your metabolism while at rest.. Try strength training 3 times a week to start. It also helps tone your body .Sometimes the scale will not budge but by adding weight lifting your clothes will be looser. Hope this helps.

I'm with you on the "if it ain't broke don't fix it," but on the other hand, it's also good to mix things up. The same routine gets boring. I suppose if you cut down cardio in favor of weights, you will burn less. You also want to be careful you don't overeat because you overestimate the calories you think you burn due to weights. Also, if it isn't working after a week or two, you can always go back.

I've been doing cardio 2-3x/wk (spin and run) plus weights 2x/week (8 basic stations, 2 sets of 8-10) and counting calories since January 13 and I've gone from 289 lbs to 261 as of last Friday. I don't know if weights help or not, but I like getting stronger. I'm losing weight like crazy so far, look better, feel better. If I ever stop doing this it's because I'm crazy!

Not insane, but cautious....and that's ok.

You're not changing anything, you're adding something.

The idea is to make sure you;re doing stuff that helps...for example you;re probably like me and don;t need to bulk up so what you need is rep's and sets with light weights. e.g. working the meat you got on ya.....also, make sure you go in to the cardio side and add in how LONG you did strength training and get the bit of cadio from that.

The thing to do with this MFP thing is to remember to do your weekly weight ins. Why is this important?

It takes more activity to burn calories when you are lighter (i.e. weigh less). I don't exactly know why but I think more calories are going to the muscles than being sotred as fat.

OK blah blah blah...for me? I try and burn as close to 1100 cals a day. Sometimes I'm over sometimes I'm a little short, but I do something everyday. That combined with tracking my cals (my goal is 1400 I try to keep it to 1200) has been great and I am seeing the muscle shapes popping out from under the ever being wave of body goop.

About 40 lbs to go...but its all good brother. Keep on chugging long.

Just remember to weight in, eat your min calories and try and burn at least 1000 a day (if you can - work up to it).
