Getting into shape

My buddy Jon and I decided that I should try to get into shape and try to fight (amateur) in the next 2 months before I start school. I have been going back to Jackson's about once a week and have really been enjoying it. Jon, who has cornered all of my previous bouts, said he'd like to train me for this one; he decided that my technique is ok, but my cardio needs lots of work.
I'll log what I do every week and we'll see if it gets less difficult.

Monday:
Shin conditioning at my desk.*
After work -

• run 1/2 mile to track
  
• sprint 100 meters, jog 100 meters, sprint 100 meters, jog.... a miles worth
• run 1/2 mile back

It was really cold monday. My ears hurt really badly. Imagine the sound of country music. Worse than that....barely. After about 15 minutes of sitting, I felt great.
Tuesday:
Shin conditioning at my desk.*
Training at Jackson's

• Warm up with the class doing squat jumps, mountain climbers, push-ups, sit-ups, hip triggers, hand/feet combos, and footwork drills.
• Hit mitts with Jon. Work on staying long with my 1-2, then coming in with a left kick or right hook depending on what's there. Did one warm up round and two hard rounds. This got me really tired.
• Sparred 1 round with a fast 205er that roughed me up and 2 rounds with the best Thai boxer there that night. I'm kind of ashamed to admit this, but I ducked out of the first round about 15 seconds early because I thought I was going to puke. I am definitely not in fighting shape.
• Things to remember: keep my chin down when I back up and when I'm throwing hooks

* shin conditioning is pretty important. We use our shins (not fragile feet) to kick as well as block (called checking) opponent's kicks. It's important to strengthen them and deaden the nerve so you won't think about checking with them.
Here is what I do:
Get some dowel rods and tape them together, like this:







Then, bang and roll your shins with 'em!
(sorry I'm wearing black pants. It makes it hard to see. I think people that sit close to my desk always wonder what that crazy noise is. I usually do it for a couple minutes, but that makes for a really awkward video.)
