So, I got my new heart rate monitor on Monday and have been testing it with various exercise activities I do.
I'm wondering if it's actually accurate and looking for comments from other folks that use one.
I have been estimating, based on SP's calculator and other online calculators, that 1 hour of Jazzercise, for instance, burns about 450 calories for a high intensity session. While wearing my HRM yesterday and today, I had "calories burned" reported at 864 and 906 for the 1 hour session. I was working moderately hard, within what I consider to be an acceptable beats per minute zone.
This seems to be really off from what the calculators I've been using have reported.
It makes me wonder, have I been underestimating my burn all this time and thus, under-eating when I was in a losing weight program, putting myself in to starvation mode? It could certainly explain a lot.
I posted a link to the model I purchased in my last blog - it's a Timex Ironman Digital Zone HRM.
So, I would love to get some thoughts on this. Do you use a heart rate monitor? Do you think they more accurately estimate your true calorie burn for exercise? Thanks!

I've been researching and wanting a heart rate monitor for several months now. I didn't have one last year during my weight loss journey and looking back, I think it would have been a great tool to really help me track calories burned.
My mom sent me a card for my birthday in May with some $$$ for whatever gift I wanted to choose, and I knew I wanted to put it towards a HRM, so I redoubled my research efforts. Two weeks ago, a good friend of mine decided she wanted to have her going away party (she just moved to AZ for a new job) as a bingo night at a local hall. I'd never played before and we had joked about going several times in the past few months. So, a few other friends and I met up at the bingo hall to play some games, have some laughs and wish our friend well in her new adventure. Little did I know that I was going to be a $400 winner on one of the last games of the night. Woohoo! DH and I decided to put a portion of the money towards our landscaping project, a portion towards baby stuff, and to split the rest between something for me and house-money. I knew that I was going to combine my birthday money from my mom with my winnings to get a really good HRM. All I needed was a sale!
So, 4th of July rolls around and Sports Authority has -the- HRM I want only sale for 25% off regular prices. Pefect! I'm now the proud owner of a Timex Ironman Zone Training Digital Heart Rate Monitor.
Just took it out for a test drive on my typical "dog walk" in the neighborhood and I'm pretty impressed. Easy to work, watch doesn't look ridiculous on my tiny wrist, chest strap is comfortable. I just wonder, is the "calories burned" feature really that accurate? I assume that it's got to be more accurate than some other estimating features, but I really wonder if I burned 369 calories on a 25 minute jog/walk in my neighborhood (hilly though it may be). I don't think that following the instruction booklet's guide for estimating my submax HR is a very good idea at 7mos pregnant, so maybe my estimate is off.
Here is some info on calculating your MHR (all kinds of diff formulas; I used the Gulati women-specific formula www.brianmac.co.uk/maxhr.htm )
I can't wait to see what it says I burn for Jazzercise. I think I've been -way-underestimating my calorie burn there.
That makes me wonder, too, then, am I -way- underestimating the amount of calories I'm eating?? How can I account for my 30lb weight gain with this baby if I've been consistently burning many more calories in my workouts than I've been tracking? Only seems to make sense that I haven't been tracking everything I've been taking in.
Anyway, I'm psyched to have this new tool in my hot little hands. I think it will really help me stay on track for the rest of this pregnancy and assist me to get rid of this weight as fast as possible once the baby is here.
wOoT, new toys!

I managed to calm myself down over the weekend, especially in light of most everyone's positive support, here and elsewhere, and had a pretty good week this week in terms of body image and positive thinking. It helped that I was so busy with work that I didn't really have time to be thinking about this. It also helped that I got my hair cut, which I had been wanting to do for about a month now. Glad I did, too, because my stylist is also expecting and yesterday was her last day at the salon. I got in just under the wire!
I am thankful for all of you that posted sympathetic comments, positive encouragement and in general were understanding and supportive of my issues in the past week. This is why I love SP so much - I know I have great people behind me every step of the way, reminding me I can get back up and keep going anytime.
I also appreciate that everyone's journey through this is different, and really applaud the level of acceptance and support despite the differences. We are such complex beings - there is no one right way to do pregnancy, or weight loss, or life for that matter. Everyone makes their own way and whether I regret something down the line or not, this is forming part of who that future person will be. I always tell my patients (and myself), I wouldn't be where I am today if not for the choices, both positive and negative, that I made in the past. I'm not "missing out" on anything during this pregnancy journey just because I happen to be having difficulty with weight gain. I am still joyful about the arrival of my child, I am still in awe of the awesomeness of the human body and what it can do - I am also a thinking, conscious, emotional person that has trouble with not feeling my best. According to Ron Weasley from "Harry Potter and the Half-Blood Prince," one person can't feel all that at the same time, they'd explode! Well, I haven't exploded yet, though I have wanted to at times. It just makes me that much more prepared for all the crazy things parenting will throw at me down the line, right? I just wanted to thank you for your comments and support one more time. I appreciate it.
Anyway, I hope you all have plans for a fabulous weekend. If you're in the USA, enjoy your 4th of July holiday!

Everything is fine with the baby - heart beat a good 151bpm, size is measuring fine, head down, everything on track for 26.3wks.
However, I have gained another f'ing 10lbs since my last visit about a month ago.
This puts me up to 183lbs, somewhere I never wanted to be again in my life. A mental place I hoped to never have to come back to - reminding me of everything bad about being fat that I thought I was done with. A total gain since the beginning of this of 30lbs. sh*t.
I am so disappointed in myself and my obviously bad food choices or whatever has caused this ridiculous amount of weight gain in 4 short weeks. Seriously? 10lbs?
I am so upset right now, it is hard to even articulate the amount of emotional distress this is causing me.
I cannot wait to be done with this process and just have the baby and get back to my real body. I am seriously thinking I will never repeat the pregnancy process in the future. This is just too much.
What a way to start a weekend.

I told myself at the start of this week that I could do five days of Jazzercise in a row and that it would help me feel better about a lot of things.
So I did - I went every day this week (M-F) at 4:45pm - and it was fantastic!
I even did most of Thursday's high impact moves instead of low impact because I was feeling extra energetic.
It makes such a difference for me to exercise regularly rather than not. I start to get weepy, emotional and overall become a sad, sad person when I don't keep myself moving. It's been a powerful realization for me, especially in light of this pregnancy.
I had multiple class participants and even a few of the instructors compliment me on how great I'm looking and how impressed they are that I'm still there, working hard. Having that positive support is a huge help in my mental work of accepting the pregnancy process.
So, I think I'll do a repeat next week, though I will have to vary it slightly as one of my best childhood friends will be in town visiting on Monday. So I'll do Tues-Sat instead :)
Hope you are finding some motivation to keep moving this weekend and making plans for next week that include some fun exercise!
Also, shout-out to all my new blog commentors and SparkFriends - I'm excited to be a part of the Fit and Pregnant team and so thankful for the Spark community reaching out to support me. Thank you for your kind words and positive support. You have been such a tremendous help in the past few weeks, you have no idea
