Elevate Your Cardio Workout with Infrared

I recently had an encounter with a treadmill. Normally, for me, I will avoid treadmills because I like cardio that is more interesting. A treadmill to me is just boring and it takes too long to get to a warmed up state. I am used to sauna HIIT training, or isometric infrared training. I am not used to waiting so long to warm up.

On this day in my travels to the HOTWORX convention in Dallas, I decided to use a treadmill to get some cardio in after weight training. There I was, trudging on a treadmill waiting for my heart rate to get to a good cardio level and it felt like it took forever. I hate wasting time with my workouts.

Enter HOTWORX with MORE WORKOUT, LESS TIME…perfect! Training inside of the patented HOTWORX infrared workout sauna delivers a much higher quality cardio session by far. Not only does it take way less time for your body to warm up and for your heart rate to get to the right level, the infrared energy is penetrating your skin delivering all of the benefits of infrared therapy!

The nitric oxide effect of training in an infrared environment causes blood vessels to dilate allowing blood to flow more efficiently. This vasodilation effect increases the transport of oxygen to muscles making for a stronger, more effective workout.

Infrared saunas enhance the endothelial function. The endothelium is the inner lining of blood vessels. Dysfunction in the endothelium can contribute to heart disease. Some research suggests that infrared sauna use may improve endothelial function, making blood vessels more flexible and responsive.

The Official Publication of The College of Family Physicians of Canada published evidence about far-infrared saunas for treatment of cardiovascular risk factors and concluded that:

Although the evidence is limited, it does suggest a number of benefits of FIRS [far infrared sauna] use, including effects on systolic hypertension, New York Heart Association class and clinical symptoms of congestive heart failure, premature ventricular contractions, brain natriuretic peptide levels, vascular endothelial function, exercise tolerance, oxidative stress, chronic pain, and possibly weight loss and chronic fatigue. No adverse events were reported in any of the studies. (1)

The mention of exercise tolerance in that publication article was impressive to me. Without a doubt, the more tolerant you can become to the pain and difficulty aspect of exercise, then the more likely you will continue to workout regularly. The evidence has been clear for a long time that exercise can benefit your cardiovascular health. Recently, it has become increasingly clear that infrared saunas can benefit your heart health too.

Why not practice both exercise and infrared sauna at the same time?

HOTWORX promotes 3D Training which does combine the two along with elevated temperatures in a fusion of isometric exercise or HIIT training, heat and infrared energy to give customers the best of all worlds for a more elevated cardio workout.
