Cross fit

I have begun a new era of training. I want to run a half marathon in less than 3 months and I NEED to get in shape, and fast! So I have gone back to the gym full time, working out, Ride Classes and training with my trainer Kevin 3-4 days a week doing Crossfit.
What is Crossfit you ask? Crossfit is... a strength and conditioning program based around functional movement patterns. They are anaerobic based workouts to increase power, strength, speed, agility, balance, flexibility, coordination, cardiovascular endurance, accuracy and stamina. Sounds easy enough right? Yeah...NO!
Here is workout from Friday...
36 Burpies
36 push ups
36 Deep knee squarts
Run .25 = one cycle...you have to do theis for 3 cycles for time...
I managed to get it all done in 18:54, I felt like dying when it was over, but I felt great.
I knew I had been at the gym and really worked out.
Tuesday's workout was 5 exercises for one minute NO BREAKS...3 cycles

Brian is going to join me on Friday night to see what kind of hell he puts me through...thankfully I don't pay for this punishment but the others in the class pay $400.00 a month for this punishment. I watch his kid, I think he is making out in the deal.
