Is 30 minutes of cardio enough?

For the bulk of my journey, all I did was do cardio for 30 minutes...and I lost just fine.

What you are seeing is the muscles retaining water as they repair themselves... and it should even out the more that you exercise and adapt to your program.

Thanks for asking this question! I'd like to hear what everyone has to say too. I'm doing about the same thing you're doing but have started adding some toning and light hand weights. So far I've lost approximately a pound a week.

I lost 45 lbs a few years ago, and I was doing like 40-80 min cardio every day and it worked awesome pounds melted off, But now I gained like 5 lbs back and I am just trying to lose that, but i am doing 30min a day and its just not happening. I am starting to do 60 min a day now and that should do it.

Exercising 30 minutes a day should be enough. I would suggest analyzing what you eat a little more closely. I assume you are using the food tracker here, but if not you should start. And my biggest problem has always been portion size. I know it's a pain, but we really need to measure everything until it becomes second nature. If you're doing all that, maybe your daily calorie count needs to be adjusted. Many folks on here have said when they weren't losing they bumped their daily count by 100-200 more and then started seeing results. Seems opposite of what we would expect, but our bodies are crazy machines sometimes.
Good luck!

I am starting my fourth week of my new fit lifestyle.. I am working out five days a week.. M-F for 30 minutes early in the morning before work.... I take weekends off to rest & be with my Family.

I'm doing 30 minutes of cardio 4-5 times a week first thing in the morning and strength training 4 times a week after dinner. I don't do cardio on the weekend and It's working really well for me.

I weigh myself one week and I am up 3 lbs, the next I am down 2lb and then today up 3 lbs again.

I weigh myself every morning. You'll see those ups and downs on the scale but you'll also see what's happening in the middle. If you only weigh in once a week you could be missing the day that you're down 3 lbs.

I see some small changes & less fat in my upper arms. I also feel great about myself overall for getting up and working out.

Focus on your success and not the shortcomings. Like you said take tape measurements occasionally and check those. It could be that you're shrinking your waist even though your weight is the same. Use the tape with the scale. In all honestly your end goal is really about the tape measurement more than it is the scale but both are measurements of progress.

any advice? should I up my cardio to 40 minutes?

Start doing some HIIT (High Intensity Interval Training) in your cardio. Do 5 minutes on a flat surface and then 5 minutes on a 3% - 5% incline. Alternate the flat/incline throughout your entire exercise time. What's your diet look like? If you're exercising as much as you say you are and not making any progress you need to reexamine your food intake. You can always out-eat your exercise. The kitchen is probably 60% - 70% of your success.

When you look back at all the fitness videos and fitness trends cardio has always been upfront but what people don't understand is running, while it gets your heart rate up its a constant. I use to run all the time and had the same problem I would even do the stair climber and still wouldn't see much of a result. It wan't until my boyfriend who is a keinseology major started showing me interval training that I started to see real results. He would have me run 400meters then doing at least four differnt types of excerises in between and I would run again and repeat the exercies at least three to four rounds. I started seeing my stamina increase. I felt pumped and uplifted wanted to try new things. I then turned to P90X and What Tony horton calls Muscle confusion and interval training (like I said before) which has increased my stamina even more and helped tone my arms and legs along with other places I didn't even realize could get toned. I would also take a look at tony's ten minute videos he uploads on youtube. they are very helpful and can show you ways to not only lose inches but tone up. Because what most people dont realize is muscle ways more than fat. So it just might be your losing the fat and gaining muscle in your legs, which is what I was doing. I have been training for two weeks now and have only lost two pounds but have already lost several inches in other places. I say its not just about cardio but toning is a big part of your weight loss success. Another helpful tool I have used was the Biggest loser. They have great strater workouts and are very motivating and postive.

Another very very helpful tool is the heart rate monitor like someone suggested! I just started using mine it even calculates a more accurate idea of how many calories you burn. It can also tell you when your in your own target heart rate zone and for how long you were there.

Lastly, Food Intake! I would say not only is staying in your target calorie goal a big helpful tool but also staying away from sugars. I found that almost everyday i may have eaten the right amount of calories but i would go over in my sugar. doesn't matter how hard you try to keep the weight away the sugar will be your nemsis every time! I agree with the idea of portion control! Once you get your metabolism going it just keeps going all day and you will want to eat at least six small a day. What people don't understand is your diet is just as important as your workout. It's what fuels you!

You also need to keep in mind that the less you have to lose the slower you're going to lose it than say someone like me who has a whole extra person's worth of weight to shed and can lose a few pounds a week. Just keep staying healthy, drink your water and try not to let the number on the scale get you down.
