Fitness classes are becoming more popular these days, and not only do they offer an intense workout, but enjoyment as well. Fitness classes are a great way to exercise with friends without getting bored and are usually offered for free at your local health club. Most fitness classes are designed to target the cardiovascular aspect (getting the heart rate up) while only a few integrate the entire body into the workout. Below is a list of the most popular fitness classes.

如今，健身運動越來越流行，它不僅能提供大強度的運動，還能給你帶來快樂。不僅能讓你與朋友一起進行有效地鍛煉，還能為你擺脫枯燥和乏味，有時還能得到當地健康俱樂部為你提供的免費服務。大多數健身運動的目的，旨在提高人體心血管系統的機能（加快心跳速率），使整個人體全身心地投入其中。下面向大家介紹一些最為流行的健身運動。

Spinning:

Spinning is an aerobic exercise that takes place on a stationary bike. The class is designed to target the heart rate as well as the lower body (quads, hamstrings, and glutes). Each class typically consists of loud motivating music combined with varying speed and resistance levels to maximize the workout. Spinning is an intense workout that burns around 600-1000 calories per hour (depending on the person). This is a great class for those with knee/ankle problems and varying fitness levels due to the fact that you can exercise at your own pace. Give it a shot!

動感自行車

動感自行車是在固定的自行車上進行的有氧運動。該項目運動不僅可以鍛煉下肢（股四頭肌，腘繩肌和臀大肌），還可以提高心率。通常在動感十足的音樂節拍下，結合不同的速度及阻力練習，使運動達到極至效果。動感自行車是一項大強度的運動，每小時能燃燒600-1000卡路里的能量（依個人不同而有不同）。由于這項運動能依自己的節奏決定運動的快慢，所以對于膝關節/踝關節有問題及健康狀況不同的人都是一項極好的運動。試一把看看！
