On Friday my friend Mary and I decided to go try out the new HIIT class at the local YMCA.

**High-intensity interval training** (**HIIT**) or **sprint interval training** is an [exercise](http://en.wikipedia.org/wiki/Exercise) strategy that is intended to improve performance with short training sessions. HIIT is a form of [cardiovascular exercise](http://en.wikipedia.org/wiki/Cardiovascular_exercise) which is beneficial to burning fat in a short and intense workout.

I knew that I was going to be sore, I just didn’t know which muscles it would be. We talked to the trainer afterwards and discussed diets, training and the such and then we went and hit the lap pool. After completing six 25 meter laps, I was finished for the day. I could already feel my muscles getting tight, so i took time to stretch afterwards.

Bring on the delayed onset muscle sorneness!

Saturday morning was the most pain I’ve been in since the last time I hit a weightroom full force in college. During that time I was muscle bound for about 2 weeks. I could hardly lift my backpack. Saturday was no different. My legs were killing me and felt like jelly! Instead of sitting around whining about it, I hopped on my bike and went for a quick two mile ride around my neighborhood to get loosened up.

Before going to bed I popped some anti-inflammatory meds and iced down my screaming quads before dosing off to sleep. Sunday seems a bit better. My legs are still sore, but not as bad.

Like all good things, I should know better than to hop into any class called “high intensity” and just start going crazy, it’s something that I’ve got to work up to.

Without a doubt I’ll join the YMCA so I can start doing laps and building up my cardio before I go to anymore classes.
