The truth about raising your heart rate mid-workout when pregnant
Maternal health and fitness pros weigh in on whether the 140 bpm guideline is an accurate way for expectant moms to measures their exertion during exercise.
Welcome to the Well+Good Healthy Pregnancy Guide, a week-long series on how SoulCycle-loving, leggings-wearing, kale salad-obsessed women can bring wellness into the next nine months (and beyond).
The notion that it’s unsafe for expectant moms to have their hearts beat more than 140 times per minute has caused plenty of women to take a, ahem, pregnant pause when it comes to prenatal workouts—and if you’re just not feeling your regular 6 a.m. classes when you’re busy growing another person and feeling nauseated 24/7, there’s zero shame in that.
But that seemingly arbitrary bpm benchmark can be challenging for physically active women who are used to getting things pumping well above that threshold on the reg, likeIntenSati instructor (and Well+Good’s fitness historian) Natalia Petrzela.
“I tried the 140 bpm test a few times with my first pregnancy…but it was pretty clear that one-size-fits-all standard didn’t fit me,” she says. “It was torturous to try to stay that low and still get a workout.”
That’s because so many exercises that add a sweaty layer to your pregnancy glow are going to elevate your heart rate above that 140 threshold. For example, a spin class sees heart rate averages spike anywhere from 170–190 bpm, and a long, slow run ranges between 139–152. So does that mean you’re done doing cardio until you deliver, or can you pull a Serena Williams and keep rocking your regular routine?
Here’s what maternal health and fitness pros say about the heart rate test—and their advice for approaching exercise when you’re expecting.

How the max heart-rate myth got started
The idea of a 140 bpm pregnancy threshold isn’t so much an urban legend as an outdated measurement for maternal health—it was introduced first in 1985 by the American College of Obstetricians and Gynecologists. Their cardio cap was extremely restrictive and based on the scant amount of research on pregnancy and exercise available at the time, which was mainly drawn from animal studies. Doctors’ main concerns back then were that strenuous exercise could affect the fetal heart rate and birth weight of a baby despite a lack of evidence showing either to be true.
But since then, the science community has found significant proof that working out while pregnant provides some serious health benefits—and the ACOG’s evolved its standing on prenatal exercise several times over the past few decades to adjust to the increasingly active lifestyles of modern women. The committee of women’s health care physicians now recommends expectant moms get in at least 30 minutes of moderate exercise a day (unless advised not to by their doctors). Still, despite being debunked (in 1994) by the very organization that introduced it, the myth of the 140 bpm persists—kind of like the misconception that all fats are bad for you. So is there actually a max heart rate for moms-to-be?

“Heart-rate monitoring is an outdated and old recommendation for assessing how hard your body is working during your workout,” says women’s health expert and OB/GYN Sherry A. Ross, MD. “If you exercised regularly before you got pregnant, then you don’t have to worry about monitoring your heart rate during exercise. Currently there’s no specific recommendation for your heart rate during exercise for pregnant women.”

Measuring max exertion
But just because it’s technically okay to hop in the saddle and tap it back in a spin class like Beyoncé, that doesn’t necessarily mean you should.
When it comes to how hard you can push yourself during a work out, “each woman is different,” says Malissa Wood, MD, co-director of the Corrigan Women’s Heart Health Program at the Massachusetts General Hospital Heart Center. “We do recommend that they exercise no harder than the level at which they’re still able to carry on a conversation while exercising.”
This method is known as the “talk test,” and Dr. Wood advises that a healthy heart rate is anywhere from 110–150 bpm, depending on the fitness of the mom. (But that number could potentially be higher depending on her activity level prior to pregnancy.) The key is to not push to the point of feeling lightheaded, short of breath, or exhausted. For many active women who are used to working out at a certain level before getting pregnant, these more individualized assessments are far more useful.

Sweating for two
Among the supporters of the shift in exercise safety measures are Paola and Pamela Del Hierro (who are known on Instagram as The Iron Twins). The fitness instructors and endurance pros are trainers at the Spartan Gym in Miami—and happen to currently both be pregnant. The duo say they prefer monitoring their activity levels using measurements that take their overall fitness into account.

“We’re in great shape—and because we’re athletic people, we [can] keep doing what we were doing,” Paola says. “We’re focusing on light-weight, high-rep exercises/circuit training at moderate intensity—on a scale of 1–10, we would say 6–7.”
The twins are staying away from high-impact workouts that could be hard on their joints, like box jumping, jumping rope, and running on cement, as well as sit-ups, heavy lifting, and inversions. Instead, they favor things like plank exercises, beach, runs, and knee pushups. And the Del Hierros recommend their expectant clients stay active until delivery as well. Why? “It prevents complications down the road and aids in faster recovery,” says Paola.
When it comes to building strong, sculpted glutes, most of us focus on big moves like squats and deadlifts. But if you want to truly level up your lower-body strength (and get that lifted, rounded shape), it’s time to give your upper glutes some serious attention.

“This area is often ignored,” says Holly Roser, CPT, a certified personal trainer and owner of Holly Roser Fitness. And that really is a shame. The upper glutes—specifically, the gluteus medius and gluteus minimus—are the secret weapons behind hip stability, posture, and lower-back support.
Strengthening them doesn’t just help with aesthetics; it also boosts athletic performance, prevents injury, and improves overall mobility. Whether you’re an avid lifter, a runner, or just looking to move pain-free, targeting this area can make all the difference. (NOt to mention that ignoring it could lead to a glute imbalance.)
So how do you engage these often-overlooked muscles? It’s all about strategic activation and mind-muscle connection. We asked top trainers for the most effective upper-glute exercises that actually work, from banded hip abductions to single-leg deadlifts. Ready to fire up those glutes and feel the difference?

First things first: A refresher on upper glute anatomy
When exploring any glute-focused exercises and charting out glute goals, it helps to understand our glute anatomy.
Your glutes are comprised of the gluteus maximus, the gluteus medius, the gluteus minimus, and the piriformis, according to ACE certified health coach and personal trainer Araceli De Leon, MS.
Where your gluteus maximus is the largest and most superficial of the glute muscles (meaning that it’s the outermost layer), your gluteus minimus is the deepest glute muscle, located underneath the gluteus maximus and gluteus medius, De Leon says.
Meanwhile, the gluteus medius is what we know to be the upper glutes.
“The gluteus medius is responsible for abduction or lateral raise and rotation of the hip joint,” De Leon says. “However, the gluteus maximus is so large relative to the others that it is also part of the upper glutes.”
From an appearance perspective, certified personal trainer Amy Schemper, CPT adds that the gluteus medius is “responsible for the ‘glute shelf’ look” that many desire.
What are the benefits of upper glute exercises?
When you do upper glute exercises, whether they’re standing or seated, Roser says you’ll experience numerous benefits—not just in the way you feel, but also when it comes to your athletic abilities.

“You’ll reduce lower back pain, knee pain, and the risk of ankle sprains, as this important muscle is a strong stabilizer,” she says. “You’ll also notice you’ll have a faster running speed and be able to increase the resistance used in your workouts.”
The reason? Stronger upper glutes lead to more overall bodily stability.
“Besides keeping our hips level and stable, our upper glutes have a very important job in our overall biomechanics, stability, and balance,” says Nashville-based certified personal trainer Bianca Vesco, CPT. “When we walk and or run, our upper glutes aid in stabilizing our pelvis. They also play a critical role in maintaining an efficient and safe lower body.”
There’s also another benefit: You’ll notice a more lifted and pronounced booty, Roser says. So if you’ve ever wondered why your bum is flat at the top, it’s because you need to incorporate upper glute exercises into your routine.
The ideal reps and sets to build your upper glutes
Before diving in, take a moment to consider your upper glute goals. Do you want to strengthen, stabilize, or maintain or build a shelf? You’ll want to tailor your routine to fit your fitness dreams, according to Vesco.
“Are you trying to build muscle mass and strength by lifting heavy weights?” she asks. “Are you correcting an imbalance or rehabbing an injury with a resistance band?” In either scenario, you can expect upper glute benefits. The way you go about them just differs.
Here’s what we mean: The number of reps and sets you perform is dependent on your glute goals, as is the amount of time you take to rest between each.
“If you are aiming for muscle hypertrophy and added mass, aim for heavier weights for lower rep ranges—four to eight repetitions—for three to five sets during your larger compound movements such as squats, lunges, deadlifts, and hip thrusts,” Schemper says. “If muscular endurance is your goal, find a weight you can maintain for 12 to 20 repetitions for three to four sets for larger movements and an elastic mini band around knees or ankles for 15 to 20 repetitions on smaller movements.”
Meanwhile, if you’re exploring upper glute exercises to correct a muscle imbalance or rehab an injury, Schemper says to start slowly with low weights, resistance, and reps, and gradually increase as you feel stronger.
No matter which approach you take, you want to feel challenged.

“At the end of the day, you want to be progressively overloading the glute muscles to see change,” Schemper says. “If something feels too easy, it’s probably time to increase your weights, resistance, reps, or sets—or all of the above. If you’re fatiguing quickly or not able to finish sets or reps, it’s time to take it down a bit.”

The best upper glute exercises to add to your routine
So, how do you work the top of your glutes? According to Schemper, the key to building upper glutes is to focus on hip abduction (moving away from the center of the body).
“However, remember no muscle works in isolation, so while smaller isolated movements help target the upper glutes, it’s important to work the lower body with larger compound moves like squats, deadlifts, and lunges,” she reminds us.
Although you can work your glutes by walking, running, and other everyday functional movements, there are some exercises that can really boost booty gains. Here are nine upper glute exercises that are sure to make your buns burn.

What not to do: Habits that could weaken your glutes
If you regularly do many of these exercises but don’t seem to be noticing any change in the look or feel of your upper glutes, you may be engaging in other behaviors that’s voiding out your hard work.
“You may not be lifting heavy enough, eating enough for your energy expenditure, or you may need more variety in your glute workouts,” Schemper says. “The key to engaging your glute muscles for growth and strength is to make sure you’re actually utilizing the right muscles. In traditional movements like squats or lunges, our quadriceps muscles are our primary movers and tend to do most of the work. To turn on the glute muscles, be sure to get low into the movement and push through the heels as you contract.”
It’s important to also be mindful of your pelvis during all upper glute exercises, Schemper says.
“Many of us experience an anterior pelvic tilt (where our pelvis is tilted forward) which can affect our ability to activate our glute muscles during exercise,” she reveals. “Banded glute bridges and deep core exercises can help correct anterior pelvic tilt, as evidenced by this study1. With a stronger core and more neutral pelvic alignment, our glutes can better engage in lower-body movements.”
Frequently Asked Questions
How do I give my upper butt a natural curve?
Be consistent—and patient. “If you’re looking to build a stronger, more muscular butt, it’s going to take some time,” Vesco says. “You have to lift heavy with a plan, you have to eat more to fuel those lifts, you have to stay consistent in the gym, and you have to show yourself grace. Rome wasn’t built overnight and neither is a bigger booty!”

How do I know if my upper glute workout is working?
Remember: Upper glute gains take time. You may feel like your hard work isn’t accounting for much, but Vesco reminds us that there are studies that suggest optimal glute growth can take between 18 months and two years to really witness.
“The work is never over and consistency always gives you the possibility to expedite that process,” she says. “However, training for life is a lifelong journey and taking care of your glutes and overall leg strength is a surefire way to make sure you’re still strong and able-bodied at 80 years old. Strong glutes, strong legs, strong life.”
Can you work out your glutes two days in a row?
TL;DR: It depends on your skill level and overall fitness.
“There are many aspects to consider when discussing exercise recovery, including training or exercise volume and frequency, adequate sleep, proper nutrition, training periodization, rest days, and more,” Rachelle Reed, PhD, an exercise physiologist, explains. “Recovery is an important part of a training program and aims to restore the body to homeostasis [a balanced state] and occurs during the time outside of an exercise training session.”
With that in mind, if you’re new to resistance training—and especially if you’re performing large muscle, multi-joint exercises like squats, lunges, deadlifts, and hip thrusts—a 24- to 48-hour rest period is ideal.
“Basically, monitor your perceived soreness levels,” Dr. Reed says. “DOMS—delayed onset muscle soreness—can start and last anywhere from 24 to 72 hours or more depending on a variety of factors. So, your best bet is to start slow and monitor how you feel. After a few sessions, you will understand how your body is reacting.”
Once you become more experienced with upper glute workouts, it’s totally fine to train back-to-back, according to Dr. Reed—though, she still recommends switching it up for the most noticeable gains.
“The most effective programs will mix different movement patterns, loading, and other techniques to progress efficiently and safely,” she says. “The main point to note while going for booty gain will be you are aiming for hypertrophy [increasing muscle size/volume] and adequate, but appropriate for your fitness level, loading will be highly important.”
How many times a week should I work out to grow a butt?
There’s no one set answer.
advertisement
“How often you should perform these exercises depends on how heavy you’re lifting for them,” Vesco says. “Heavy lifts for muscle growth and strength should only be done one to two times per week.”
Can you change the shape of your glutes through exercise?
Yes, but it will take time.
“Anyone can change the shape of their butt, but it depends on how drastic you want that change to be,” Vesco says. “We all have our own goals and standards but if your goal is to grow a bigger booty, you need to focus on the entire backside, not just the upper glutes. Building strength in the gluteus maximus, medius, and minimus will get you there much faster.”
Additionally, it’s important not to overwork your glutes in hopes of faster results.
“You definitely need to stimulate the muscles to help them grow, but training them too much can be counterproductive if you don’t give them time to rest, repair, and rebuild,” Vesco says.
What are the most useless exercises for building your glutes?
“Bicep curls!” Vesco jokes. “‘Building’ can mean a lot of things for a lot of people but if you want to actually increase the size of your backside, you have to lift heavy weights consistently.”
Why are my upper glutes not growing?
As hard as you may be working to grow your booty, you may simply be focusing on the wrong areas and glute exercises.
“If you aren’t seeing glute growth, you may be training mostly in the sagittal plane—think squats and lunges—train in the horizontal plane with banded side steps and side lunges, as well as the transverse plane with curtsy lunges, for better glute gains,” Schemper says.
It’s also possible to plateau while working out. In fact, it’s common. Your body can adapt to movements, weights, and workouts, according to De Leon. So if you’re doing all of these exercises but aren’t reaping any new rewards, she says it’s time to mix it up with more weight, reps, or new exercises altogether.
“Another example, if you’re using bands, try using cable machines; or if you’re using machines, try free weights such as barbells, dumbbells or kettlebells,” she says.
