Whether you are running, cycling, paddling, performing aerobics routines or using cardio machines, the traditional method for monitoring exercise intensity is to measure heart rate. For the purpose of general fitness improvement, this allows you to determine whether you are working within your aerobic training zone – the intensity that most effectively improves the cardiovascular system without becoming uncomfortable and causing premature fatigue.

However, few people are good at checking heart-rates: they either cannot find their pulse quickly enough to get an accurate reading, or they make any of a number of pulse-taking errors. Also, in order to take a pulse, exercisers generally have to slow down or stop which disrupts their workout.

The other option is to use a heart-rate monitor, but such equipment can be expensive and uncomfortable.

Fortunately, there is an easier, less expensive way to monitor exercise intensity – by simply listening to your breathing.

LOWER AEROBIC ZONE RANGE

You can determine the lower level of your aerobic training zone (that level of intensity is often called the aerobic threshold) by listening to your breathing – when it becomes audible, you have entered the aerobic training zone.

UPPER AEROBIC ZONE RANGE

When are you working too hard? When you are breathing so hard you can no longer carry on a conversation without gasping. This shows that you have passed out of your aerobic training zone and crossed the lactate threshold. You are now in the anaerobic training zone – a level of intensity that results in the buildup, in your bloodstream, of lactic acid and other fatigue-producing by-products of energy metabolism.

BREATHING STUDY

Robert Goode, a respiratory physiologist at the University of Toronto, has confirmed the effectiveness of using breathing to estimate exercise intensity. He performed a study in which 30 subjects pedaled stationary bicycles while heart rates and respiration levels were monitored.

Their heart rates were checked when they were first able to hear themselves breathing. He found that this point corresponded to the lower range of intensity for improving cardiovascular fitness (the aerobic threshold). Even better, this threshold changed depending on the age of the subject – a phenomenon that we know occurs as people age. For example, the aerobic threshold corresponded to about 110 beats per minute for a 65 year-old, and 150 beats per minute for a 20-year old.

Other studies have shown that the lactate threshold corresponds to the level of exercise intensity that causes you to gasp when breathing. The lactate threshold is upper range of the aerobic threshold.

CONCLUSION

If you want to exercise aerobically, work hard enough so you can hear your breathing, but not so hard that you cannot speak without gasping.

Maybe you want to try yoga out. Maybe you practiced it before and want to start again. If you want to do yoga, you probably want to find a yoga class. You can use the following methods to find a local yoga class.

Local Gym – In addition to their weight rooms and cardio machines, many gyms offer a large assortment of fitness classes. Some gyms offer brochures that list and describe all of their different classes. Nonetheless, you can more easily find out whether or not a local gym offers any yoga classes simply by calling them and asking. When you call, remember to ask for the price. Try calling more than one gym and writing down the different prices and other details. That way you can choose the best class for you. You can usually find a whole bunch of gyms in any given community, so you most likely can find a few that have yoga classes.

Yoga Studio – Yoga studios are basically places dedicated to practicing yoga. They are to yoga practice what a martial arts studio is to martial arts. Depending on where you live, you may not be able to find a yoga studio nearby. Even if you find one or more, they may not meet your budget or your needs.

Craigslist – You can read and post local classified ads on craigslist for free. If you do not see anything on there about yoga classes, post a classified ad asking about yoga classes in your neighborhood. You can also use this method to find a yoga partner, but be very careful meeting anyone from the internet. Craiglist lets you remain anonymous when posting ads.

Ask Your Friends – If you know other people who practice yoga, ask them where they practice yoga. This will not only help you find places that offer classes, but it will also let you get immediate first-hand information about those places. You can ask the person if they recommend the classes. You can also ask friends and other people you know about yoga classes. Even if they do not practice yoga, they may happen to know of local places that offer yoga classes.

Before looking for yoga classes, you want to figure out what you want out of the classes. Figure out how much you are willing to spend. Also, figure out what type of class you want. For example, do you want one that focuses on the spiritual aspects of yoga, or do you simply want an exercise class?

Some gyms and studios may want you to sign up for a long-running class and pay upfront. Avoid doing this unless you have tried the class out, especially if you are new to yoga. You do not want to pay hundreds of dollars for months of yoga classes only to find out that you do not like yoga or the class.

You can also start practicing yoga by getting a yoga video. A video would allow you to practice yoga at home.

Whatever you do, good luck and have fun!
