I want to buy a heart rate monitor but I am not sure about what features to look for. Should I use it during strength training as well?

I haven't used the recipe calculator in a long time. It will help so much. Thanks

Bronzncolor, try the spark recipes "recipe calculator". It's a great tool! Here's a link:

I will cook a meal and not know how to calculate the calories. Example I made baked macaroni and cheese. I could not figure out how much cheese, milk, egg or butter my piece had lol. Working on it.

Lisa,

That seems like a lot of calories expended bases on your activity. My suggestion would be to consider investing in a heart rate monitor. The one thing calorie calculators can't factor in is the intensity you are doing for the activity. Because they use an algorthim based on the findings of the average person, you may be working out at a lower intensity, BUT you may also be working out at a much higher intensity than what the calorie calculators base their data on.

Remember too that as important as exercise is, rest plays a big role in our healthy living journey. Overstressing our bodies via exercise and/or a lower calorie diet can lead to a rise/lowering of certain hormones which may actually promote fat storage instead of fat burning. I am beginning to read a lot more data about the need for balance. Remember you can't rush the weight loss process so maybe try adding a day or two where you don't do any 'formal' activity and see how that works for you.

Thanks for responding Coach Nancy.

I am kickboxing M-W-F for 60 mins each time
I Walk/jog 2x/ week for 30-40 mins
I lane swim 1x /week for 30 - 40 mins
And I go to the gym and weight train 2x/week

I usually do a jog on the days I go to the gym and swimming on a day by itself.

Thanks,
Lisa

Hi A-NEW-NURSE,

Calorie calculators use an algorithm or a mathematical equation to determine calories burn so they offer just an estimate of calories expended.

Calories burned are determined by the amount of oxygen one consumed and the carbon dioxide exhaled during a particular activity--this is for all activities whether you are sitting in front of the computer or in a kick boxing class. The more large muscles you must activate the more calories one will burn.

That being said, using a heart rate monitor which calculates your calories burn based on your heart rate and using an algorthim will be a better indicator of calories burn (but still an estimate) as your heart rate is used as part of the equation.

I am wondering however, if your calories burn figure is miscalculated? That seems to be a lot of calories expended for just one week.

How many days a week are you going to kickboxing? Are you allowing recovery time between workouts?

It isn't uncommon to see a slight upward shift in weight when we start exercising, or add a new training regimen and eating better. For one the muscles are making more mitochondria which allow for extra glycogen-stored glucose in the cells- therefore, your body hangs on to more water to help with the cooling off process for exercise and for helping process energy. Your muscles will also have an increase in blood volume in order to have better availability to oxygen and removing waste, especially lactic acid.

Based on my calories burned each week (about 4000), my SparkDiet calorie range is 1600-2000 calories per day.

I just want anyone's advise on whether they think Spark People is accurate in determining/estimating calories burned.

When I put in 60 mins of cardio kickboxing it tells me this is 880 calories. (This very well may be the case as this is the most intense, hardest workout I have ever done!)

My problem though is that I do not seem to be loosing much weight. My weight has been about the same for 3 weeks now and I am getting frustrated.

Any advise would be helpful!

Thanks!
