No single reason is driving people to the millennia-old practice. Experts suspect it has something to do with yoga’s combination of physical and mental health benefits. “We spend so much time on autopilot, checking off things on our to-do list. Yoga can help people slow down,” says Sherwin. “When you do yoga, your nervous system calms down and you get out of that fight-or-flight state, Sherwin says. “Just sitting and breathing can be yoga. You’re aware, you’re in the moment, and you can find peace in that moment.” Yoga began in India and has been around for about 5,000 years, says Sherwin. “Originally it was taught one-on-one and only to men of the highest caste,” she says.

Anything that elevates our heart rate for a consistent period of time is beneficial to overall fitness, he says. “The heart is a muscle, and when you challenge it by elevating your heart rate you make it stronger,” says Dr. Laskowski. Yoga probably isn’t in the same category of aerobic exercise as running or biking, says Laskowski. But the amount of aerobic benefit a person could get from yoga depends a lot on the style and pace of the type of yoga you’re doing, he says. Yoga can also help build strength, Laskowski says. Certain positions and poses where a person must hold up part of their body weight will challenge a muscle and make it stronger, he says. It’s a good way to get your resistance training in, because yoga builds functional strength (meaning you get stronger by using multiple joint and muscle groups together rather than strengthening a specific muscle in isolation, as you might do in weight lifting). “That’s good, because that’s what we do in our daily life,” he says. Different styles of vinyasa yoga also include power yoga, Baptiste yoga, Jivamukti, and prana flow. These kinds of classes are among the most athletic and physically challenging, says Fleming. It can be difficult to keep up with the pace of a vinyasa class if you don’t have yoga experience, adds Shala Worsley, a yoga instructor at Asheville Yoga Center in Asheville, North Carolina, who is certified by Yoga Alliance. “If you want to try vinyasa yoga and you don’t have much experience, try to find a studio that offers a beginner or a slow flow class,” says Worsley. Here are a few things to know before you try it.

How Hot Is a Hot Yoga Class?

Not only can the temperature fluctuate depending on the studio (check the class description or call the individual studio to find out details), but the method of heating can be different as well, says Scupp. Along with conventional heating, some studios use a humidifier to make the room feel warmer. Some studios, like Heatwise, use infrared heat that comes from electric heat panels that are placed on the ceiling or around the room, which can feel more natural than forced-air heat, she says. The size of the room, the weather outside, and how packed the class is can all be factors in how hot the room gets, Scupp says.

Not All Hot Yoga Classes Are the Same

Yoga done in a hot environment is called “hot yoga.” Hot yoga became popular in the 1970s with a specific style called Bikram yoga, and heat is now used to enhance a variety of yoga styles. Vinyasa yoga or flow-type yoga practiced in a heated studio can also be called hot yoga. It would be a good idea to have some yoga experience before you step into a hot yoga class, says Scupp. Depending on the studio, there may be a beginner level course offered.

Pregnant Women, People With Heart Conditions, and Some Others Should Check With Their MD Before Doing Hot Yoga

In general, hot yoga is safe for someone as long as they’re in good health, says Laskowski. If a person has certain preexisting chronic health conditions, previous heat injury, certain heart conditions, easily gets dehydrated, or is pregnant, it may not be safe to do hot yoga, he says. “It’s always a good idea to check with your doctor if you’re going to try an activity that could stress your body,” says Laskowski. Depending on where you live and the size of the yoga community, you may find several types of yoga offered at studios near you. Here are a few of those types.

Hatha Yoga

Hatha yoga (pronounced HAH-ta, not -tha) encompasses several types of yoga, including ashtanga, vinyasa, and power yoga. Hatha classes tend to be slower-paced than vinyasa classes, and may not necessarily flow from pose to pose, says Fleming. Poses are typically held for several breaths before another pose begins. What is consistent across different types of hatha yoga is that the physical poses and postures are meant to be linked to your breathing patterns.

Ashtanga Yoga

Ashtanga yoga is a physically demanding type of yoga that moves quickly from pose to pose. Unlike flow or vinyasa yoga, there are set sequences that are meant to be performed in a specific order. Ashtanga yoga can be practiced in a teacher-led class or in a Mysore format. Mysore is self-guided with an instructor present but not leading the class. In a Mysore format, students are expected to know the sequence and timing of the poses from memory, Fleming explains.

Kundalini Yoga

Yin Yoga

Yin yoga is a style in which there’s no flowing from pose to pose. You stay mostly seated on the floor or lying on your back or belly, Fleming says. It’s more passive and focuses on stretching. And the poses are held longer than in other types of yoga, says Fleming. “This kind of stretching can be good for the joints in a different way than active stretching,” says Fleming.

Yoga Nidra

Yoga nidra is more of a meditation than a pose-filled yoga class. Students lie on their backs (a blanket or bolster can be used to add comfort) as the teacher guides them through focusing on and relaxing different parts of the body. People who practice yoga nidra are encouraged to “let go” and surrender to total relaxation and peace. It can be as relaxing and restorative as actual sleep, says Fleming. Props can be an equalizer to help make poses accessible to people of all body types, says Krucoff. Some people have shorter arms or a longer torso and a block or a yoga strap can help people get into a pose safely, she says. Props can also be an important component of class, as in a chair yoga class, in which most (if not all) seated poses are performed in a chair rather than on the floor, says Krucoff.

Check out the class ahead of time. Observe a class and interview the teacher if possible, says Judi Bar, the lead yoga therapist and yoga program manager at Cleveland Clinic Wellness and Preventive Medicine, who is certified by the International Association of Yoga Therapists and Yoga Alliance. Even if the class is labeled beginner, you may want to investigate further, she says. It may be that the class is beginner-level, but not intended to be the first class someone ever takes. “Sometimes beginner classes are designed for younger or fitter people or even people with a little yoga experience,” says Bar. If possible, talk to the instructor or watch a portion or all of the class before you take it.Try a slower-moving class or one designed for beginners. Make sure the teacher encourages people to listen to their body. “You should feel supported in just doing what you feel comfortable doing on any given day,” says Bar. You don’t want a class that feels like a competition, especially if you’re a beginner, she says.Communicate with the instructor. Introduce yourself to the instructor before class starts and let him or her know it’s your first class. If you have any injuries or chronic conditions, you should let your instructor know that too, says Laskowski. “They have training to help you modify the poses to help prevent injury,” he says.Don’t sweat the small stuff. Remember, everyone was a beginner at some point. “It doesn’t have to be complicated; you don’t have to have special clothing or props; it can be a very simple practice,” says Sherwin. “Yoga is about finding peace in the moment,” she adds.

Try to find a studio or class that’s convenient to your home or work, says Bar. “You don’t want getting to yoga class to be a source of stress,” she says.An online search could be a good way to see what’s in your area, as well as a way to find out what other people think of the studio, says Stephanie Keach, the owner and founder of Asheville Yoga Center in Asheville, North Carolina, who is certified by Yoga Alliance.Observe and try different classes, says Krucoff. There are many, many styles of yoga, and lots of studios allow students to have their first class free, she says.Find a community of like-minded people where you feel comfortable and supported, says Krucoff.Make sure that the teacher is well-trained and qualified, says Krucoff. Check out the credentials and what kind of training is required at the studio, she suggests. “Having a teacher who is well-trained is important, especially if you have physical limitations or a chronic health condition,” says Krucoff.Don’t be afraid to experiment. “Ideally, you should try out a few different teachers and styles,” says Keach.Be consistent. Once you find a teacher or class that you love, commit to it, says Keach. “Stick with it and attend class a few times a week,” she says. “That’s when the magic happens!”
