Krav Maga: The Beginning

Took my first two Krav Maga classes last week.  During those classes the first thing I learned is that most Krav Maga training I'll be involved in is under stress and exhaustion.  I was ready to puke a few times throughout the warmup, we haven't even gotten to the training drills or technique training.  Spent quite a bit of time punching, elbowing and kneeing a pad being held by a training partner, while wearing grappling gloves.  After that we spent some ground n' pound time with a dummy bag on the ground, with a couple of transitions from one side to the other, finished by pistol disarms.  Second class we went over ground survival concepts, mostly transitioning from having a foe mounted on us to sweeping/rolling into their guard, passing the guard and gaining the mount.  Once we had that down we sparred and tried to stand up first.  Person on the ground attempted to reverse position or tap the upright person out, and the upright person was trying to escape the guard and stand up.  If the person on the ground was able to reverse position and become upright, it was their task to now escape and stand up.  Tons of pushups, crunches, squats, lunges and kicking drills.  I tried to explain it to my wife as an hour long fight, as break times were measured in seconds and transition from drill to drill, exercise to exercise and technique to sparring was however long it took to move to that portion of the training mats.
Went down to the local YMCA after my wife got us a membership and enrolled in a new workout program, for heavy intensity and endurance.  We'll see what happens!
