Cardio Kickboxing

I went to my first kickboxing class on Tuesday since I joined the gym. My membership allows me to take whatever classes they offer and they have a good selection. So, My first day was an eye opener since I realized I had to stop for water numerous time during the workout. It was a cardio kickboxing class so all of the moves was a decent speed which knocked the wind out of me. I liked the class and I will go back but I have to get my stamina up or next time I will faint.
