I general, I tried to do a little core work with the strength aspect of the workout. Lots of body weight exercises and such. But for good measure, I threw in some planks, side planks, and hanging leg raises above and beyond the strength. I'm not a big fan of crunches, simply because I don't enjoy them, not because I have any information on their effectiveness. But I do think I may throw in a few of them in this last week.
For flexibility, of course, I have turned to yoga. I used to go to a yoga class at the gym that I dubbed "easy yoga" because of its gentle, flowing nature. From that class, I learned that I actually get better results from the gentle approach than from power yoga. And though changes in class schedule has made yoga at the gym impossible, I have tried to do one yoga DVD or download per week. I am rather partial to Sage Roundtree's Yoga for Athletes. I also did a lot of yoga downloads from Bexlife.com
SInce injury prevention is pretty much a full time concern, especially when engaging in physical activity all day every day for months on end, I'm in the process of putting together a Core/Flexibility routine or two for the apres hike, before sleep part of the day on the trail. I gotta stay injury free on the trail, too.
One week and counting!
