Zumba is a new hit at the gym and has been promoted widely as an excellent cardiovascular class and a class for those that are seeking to burn calories and tone up. Today I borrowed a video from a friend and went through the whole workout giving it 110%.
Length of class: 50 min
My sweat rate: 300 ml/hour (at 22.5 C, humidity unknown, indoor)
Heart rate: average 62% based on my own personal resting and max heart rate.
(My resting heart rate (tested): 51 bpm* my max heart rate (tested): 195 bpm**)
*Typical healthy resting heart rate in adults is 60–80 bpm, lower in athletes
** You can also subtract your age from 220 instead of testing
*** using the Karoven method (Target heart rate = ((HRmax − HRrest) × %Intensity) + HRrest )
Steps: 4500 (if walking this would give me a speed of 4k/h)
Calories burned: between 250 – 310–calculated on my weight (58kg)
The promise of burning up to 1000 calories an hour is very far away from the truth. Turns out I only burned 250- 310 calories on one session! To burn 1000 calories you would have to weigh 175 kg and above!
Cardiovascular exercise: My heart rate shows an average 62% of my max heart rate, which isn’t in the cardiovascular zone. In other words, the exercise isn’t intense enough to give you a real cardiovascular workout. You will be in the so-called fat-burning zone, but with the low amount of calories burned you would be better of doing something else at a higher intensity as at the end of the day it is calories in versus calories out.
Will this make you look like the dancers? No! Remember that the host Alberto “Beto” Perez is a personal trainer and has probably worked out his whole life. I didn’t get my abs overnight; I have worked out with weights for 12 years and been an active dancer and runner since I could walk. There are no quick fixes! If you find Zumba motivates you, then do it. Just remember that you still need to do weight training and cardiovascular workouts and watch what you are eating and drinking, for your health as well for your looks (if that is your aim).
Have you tried Zumba? What do you think of it?
