I could tell I was pushing my body to its limit. Anytime I am nearing my aerobic maximum my perception of the world collapses. Everything becomes two dimensional. My eyes lose the ability to see vivid colors, and my ears stop sensing the space around me. All you can hear is your own labored breathing, the rhythmic pounding of your own heart and a screaming innner voice that is crying for you to stop the insanity and find a donut shop!

I was at my third Aerobic Kickboxing Workout class at my gym. I'm a recovering couch potato desperately searching for a chance at redemption, or at least a smaller waistline.

My training parter looked to be a decade younger, and in roughly the same horrible physical condition as me. He was holding muay thai kickboxing pads around waist high. I feebly kicked the pads 10 times with my right leg, then switched to 10 with my even more pathetic left leg, then I moaned through 10 knucklepush ups, then 10 hill climbers then 10 jumping squats, then 10 burpees...burpees, good old burpees. Then I dimly remember smiling as I thought I was done...instead of switching places, the instructor, Kru Evil, made me do it again...and again...and again.

Was this kickboxing workout the most difficult workout of my life? Not sure...I can barely remember it. All I know is I felt amazing at the end of class. Exhausted, drenched but with a strange feeling of euphoria. I'll be back in 3 days to do it all again!
