My cardio is getting better.

So on Tuesday I looked up the WOD on the crossfit website and it was
Complete as many rounds as possible in 15 minutes of:
10 Wall ball shots, 20 pound ball
10 Toes to bar
10 Box jumps, 24" box
I had to replace a 30 lb dumbbell for the wall ball and I did knees to elbows instead of toes to bar. Ain't that good at crossfit yet. I got 8 rounds plus 1 time wall ball and 1 time knees to elbows. I did well, alot better then I though I would. I can see myself slimming out and toning up.
On Wednesday I went out in the morning and did 2 miles worth of sprints. 60/120 and got the entire 2 miles in 13:55. Even doing 60/120 I did 5 seconds better than I had hoped for my last 2 mile. So I am way excited.
