Heart Rate During Pregnancy: Do's and Don'ts

It’s undeniable that exercise is encouraged for moms-to-be with healthy pregnancies. The old guidelines used to specify 140 beats per minute as a heart rate max during pregnancy. We’ve since learned that is unnecessary and new guidelines will suggest moderate-intensity aerobic activity during pregnancy. You may already be aware of this, but what most pregnant people are not aware of is that monitoring heart rate is actually not that helpful during pregnancy. In an age of tracking all fitness moves, your heart rate pre-pregnancy may have been a good indicator of how hard you’re working. However during pregnancy your cardiovascular system changes. Your heart rate, blood volume, and cardiac output all increase during pregnancy. This means that your heart rate may not respond the way it used to. So what are some do’s and don’ts when it comes to heart rate during exercise when you’re pregnant?

DO: be aware if after exercising you’re still feeling out of breath or feel your heart beating fast. Just like before pregnancy, as you recover post exercise your heart rate should return close to your pre-exercise baseline.

DON’T: use a heart rate monitor to determine the aerobic intensity or feel limited by your heart rate during exercise.

DO: aim for moderate intensity, which can be determined by the “talk test” or RPE (ratings of perceived exertion"). During moderate-intensity exercise, you might feel winded, but you should still be able to hold a conversation. Ratings of perceived exertion (overall how hard it feels you’re working) correlate well with heart rate. On a scale of 1-10, you should feel at about 3-4 (moderate to somewhat hard). On the traditional Borg Scale of 6-20, you’d fall at about 12-14.

DON’T: use walks where your heart rate isn’t elevated to count toward your aerobic exercise goals. General physical activity is great and we should all probably move more during the day, but your stroll around the block with your two-year-old, most likely isn’t challenging your heart rate.

DO: discuss if moderate to vigorous exercise is appropriate for you. If you were generally consistent with exercise at higher intensities before pregnancy, your moderate baseline will be different than someone who wasn’t. As we’ve seen with many athletes, your doctor may also say it’s safe for you to work at a higher than moderate intensity.

So now that you understand a bit more about heart rate and exercise, go ahead and get moving. Strength training, walking, swimming, dancing, or the stationary bike are all great prenatal options.

Summer is Coming: Tips for Moms to Meet Their Fitness Goals

I’ll start with a disclaimer that I don’t love the idea of people putting pressure on themselves to up their exercise routine in preparation for summer. I firmly believe fitness is a lifestyle and the best way to sustain results is to be consistent year round. However, with that said, I also see nothing wrong with having aesthetic or other goals that make you feel confident this summer. So if you’re someone that is working toward your summer fitness goals, keep reading for a few tips.

Pregnancy Tips:

Summer can be an uncomfortable time to be pregnant. In order to stay active and continuing to make progress in your fitness consider the following 3 tips.

• Exercise first thing in the morning: hot summer days can make it harder for you to regulate your body temperature, and quite honestly can just feel draining. Use the month of May to start a morning workout routine. Working out at the coolest point of the day can be safer, more comfortable and help you stay consistent.

• Hydrate: not having enough water can raise your body temperature, and dehydration can even lead to uterine contractions. Make sure to replenish fluids after a workout. Use the month of May to get in the habit of increasing your fluids and maybe even treat yourself to a new water bottle.

• Invest in workout gear or embrace the belly and sports bra look: If you no longer have moisture wicking clothing that fits, take some time during May to order a few new tops. You’ll want to be able to dissipate the summer heat. If you exercise regularly your sweat point will be lower in order to help with temperature regulation so you’ll want to stay comfortable and have clothing that drys quickly.

Postpartum Tips

If you’re still recovering from birth or building your fitness foundation, then your goals shouldn’t change too much with the season. However, there are a few tips that will help you plan for increased physical activity outside with your little one this summer.

• Invest in a new carrier or switch to a stroller: During the cold months it’s possible you were only wearing the baby around the house or for short walks. With the nice summer days, your walks will get longer (as baby gets heavier) and that can cause neck and back pain without a supportive carrier. Take the month of May to make sure you have the right gear. Look for something with thick shoulder straps and a waist belt. Consider using a stroller for long walks until your core is strong and functional again.

• Implement a walking progression: Before jumping in to longer walks and more physical activity, use the month of May to do it gradually. Aim to increase your walks 5-10 minutes each time or by gradual distance increments each week. Use interval style training to prepare your body for longer durations.

• A little extra attention to specific muscles: During the month of May set aside 10 minutes/day, at least 3 days per week to focus on strengthening your abs, low back and glutes. Also include mobility exercises for your hip flexors and thoracic spine.

Beyond Postpartum Tips

You’ve been exercising consistently, have a strong fitness foundation and just want a little push toward your goal of more defined arms or feeling comfortable in a two piece at the beach. There is nothing wrong with aesthetics being part of your goals and here are some tips to get you that much closer.

Choose a muscle to focus on: Keep with your regular routine, but choose one muscle group to emphasize during the month of May. Include an additional 10 minutes working that muscle each workout, aiming for 3 days per week of targeted training.

Increase your cardio: If you know me, you know I believe strength training is key. However, if your goal is to see the muscles you’ve been working hard for, a little extra cardio during the month of May can give your body what you need to drop your overall body fat percentage if needed (remember, you can’t target train fat away!). Try adding some intervals to a strength workout or moderate intensity cardio on your strength recovery days.

Increase protein and water: If your plan is to add some cardio for more calorie/fat burning as suggested above, make sure you don’t lose the muscle mass you’ve worked so hard for. Aim to get at least 1g protein/kg of body weight to help you sustain muscle. Don’t forget your body needs enough water to function properly so make sure to hydrate!

So whether you’re pregnant, postpartum or further along in your motherhood journey, May through June is a great time to put these tips into action.
