Kickboxing/plyometrics

This week on thursday, during cardio class we did some kickboxing for 50 minutes. It wasn't very hard, but it sure got me sweaty by the end of the workout. My heart rate stayed between 125-140. Also, in my strength and conditioning class, we did some plyometrics. That really gets the HR going due to the short bursts of high energy neeeded. My highest HR was 185!
