According to Men's Heath, skiing will make you absolutely shredded. Okay, well, you need to put the work in, but if you do, then you can burn as

much 735 calories in an hour. 

Unlike other cardio exercises such as running and biking, skiing works your whole body at once. It engages your core, your legs, and your arms all at once, ensuring

that you'll be worn out by the end of your workout. 

You will constantly be switching your weight distribution in order to not fall over. It's kind of like paddle boarding in that aspect, except falling into a pile of snow

is a lot more of a shock to the system than falling into warm water. 

You don't need a ton of stuff to get out there and practice this sport. There are a couple of essential things, though. These include: skis (duh), boots, ski poles, and proper

winter clothing. 

REI has a nice, in-depth article that explains exactly what you should buy and why. It's a great read if you plan on not perishing while trying to

get in your cardio hours.
