Cardio instead of weight training for weight loss?

General rule of thumb is you can't gain muscle while eating at a deficit.

Strength training helps to keep from losing LBM. It also helps you lose inches. Meaning you'll be able to fit into even smaller clothes.

Cardio alone will burn both LBM and fat.

You will also be stronger if you continue with the strength training. Stronger doesn't mean that you will have more muscle. To actually gain muscle you have to eat a surplus of calories.

I just did my first 30 day shred yesterday. it was tough!! My arms are killing me today. I'm looking to tone up and only loose about 20lbs. I am hoping this work our series will work for me. What do you guys think?

Good post! I would like to add, lifting weights will boost fat burning hormones while most cardio has the opposite effect. Walking is a great exercise to burn calories, increase blood flow to the fat, increase fat burning enzyme activity, and not have a negative effect on fat burning hormones.

For weight loss all you really need is a calorie deficit whether it comes from diet or cardio is up to you. Weight training is important when you are in a deficit in order to not lose a lot of muscle mass while you are losing weight. So basically do whatever makes you feel the best but i personally LOVE weight training.

I started a new gym 1/8/13 and; I did both weights and cardio for two months but there was no weight loss. So now I only do cardio workouts, for me its working so far I've loss 14lbs just doing cardio and counting calories. Good luck!!:happy:

1. 30Ds is cardio...pretty much circuit training with some light weights thrown in

2. If you are dieting (i.e. eating at a deficit) you can't build any appreciable muscle...in fact, when you diet you lose muscle as well as fat.

3. Weight training/resistance training helps to preserve muscle while in a deficit, resulting in a better physique when you get to your goal weight.

4. Cardio is basically weight lifting for the heart...yes, you burn calories, but your cardio work should be focused on specific fitness goals, not just calorie burn...if you're using the MFP method, you're supposed to eat back exercise calories anyway.

5. Cardio and diet only will result in weight loss, but a lot of it will be muscle as well as fat in the absence of resistance training; your fitness program should incorporate all aspects of fitness, which includes cardiovascular health as well as strength training.

If you just do cardio you'll be skinny-fat. I'd rather look thinner and weight a bit more than be flabby and weight less but to each their own.

Is your food diary accurate? If so you are not eating enough to fuel any sort of workout!

I'm currently at 175, down 12 pounds since I began eating clean and working out. I've tried doing the 30 DS a few times before (but never got beyond 20 or so days of it because of my busy schedule), and I just started it up again about a week ago, but now I'm reading on the boards that what I really might want to be focusing on is cardio? I'm looking to lose weight, not gain muscle. I'm actually fairly muscular already.

Note: I'm living in a little studio in Belgium, in a tiny town, we don't even have a local gym, so treadmills and such aren't available for me, and I can't really run on the streets because most of them are cobblestones So what I'm looking for is a video program like the 30DS but more focused on cardio I guess.

30 day shred is cardio (circuit training cardio). It's a good work out but not considered strength training in the true sense of the term. I believe a good fitness program contains both strength and cardio. For strength training - focus on compound moves (pushups, pullups, planks, bench presses, overhead presses, deadlifts). Use weights that challenge you (if you can do more than 12 reps it's too light). The 'new rules of lifting for women' is a good book with lot's of info on strength training and includes a workout routine. For cardio - youtube is your friend!! So many good workouts available for free. I've recently got hooked on the Jessica Smith TV channel and the BeFit channel.

I've tossed out my scale, and quite frankly, only weigh myself once a month on the scale at the gym. I used to be a cardio bunny, doing at least 60 minutes on the elliptical 5 days a week, still feeling weak and tired and quite frankly exhausted. But my clothes didn't look any better on me, the number on the scale went down, so still feeling frustrated as hell, i threw out my scale and purchased a set of body callipers and a tape measurer, I've gone from 33% body fat to 29%, my clothes fit better, but the real kicker is I weigh about the same.

SW = 160lbs
CW = 158lbs

The only cardio I do now, literally is 10 minutes of high intensity intervals on the elliptical before I start my work out. Starting resistance level 4 for 1 minute, and then level 15 for 1 minute. Then I hit the weights hard for an hour.

Track your progress and set your fitness goals based on body fat, not the number on the scale.
