Cross Fit Training

For the last few weeks i've been doing cross fit training
It's been really hard but really awesome at the same time!
Everytime that I train, the next time i'm really sore!
For example, yesterday we did some cross fit training and we did the following:

• 40 shoulder presses
• 75 sit ups
• 75 push ups
• 75 air squats

This time around it was not timed, but it was still tiring
When we were done with that Rob told us we were going to do mountain climbers.
I didn't know what those were, none of us really did except Savage, so he demonstrated.
When he showed us we all walked out into the hallway because there was more room out there.
We all got into the position and we did several repatitions.

• 20 seconds of exercise
• 10 seconds of rest

I don't remember how many sets we did, but probablly 4 or 5 times.
All i know is if i was going to have to do one more, my legs would of given out!Today, my legs are sore, but it's a good feeling!
