Back in the saddle....

After a day of being "down" due to dental work and consequential headache.....back in the saddle today and completed day 7 of level 3 of shredding.  I can't believe it's almost over! I'm gonna be sad. I know I will still do the shred workouts from time to time....I really enjoy them. I can remember when I started and I did day 1 of level 1 and I thought I was gonna die.  Laughing at that now!!!!! Thinking about maybe investing in P90X next.  Not sure.  Any thoughts?
