I recently got a copy of the Primal Blueprint 21 Day Transformation from the library and am now going through the book. I love it! I'm on Day 4 of my own Primal transformation and am looking for a new, unique aerobic adventure. I want to move outside of my comfort zone, but all of the exercises I can come up with are well within my comfort zone!

I've thought of taking a yoga class, but I'm pretty sure any class I do will push me beyond the 55-75% max heartbeat due to the nature of physical fitness classes. The only things I can think of that are outside of my comfort zone are going to the gym and walking on a treadmill or stationary bike! Neither one sounds very interesting.

What suggestions do you have for someone stuck in a currently very muddy part of Ohio?

Activities that are within comfort zone:

Swimming
Hiking/Walking
Roller Blading
Ice skating
Biking
Horseback riding

If all else fails, I'll go to a new state park and engage in a mud-hike =)

I appreciate any suggestions you guys can give!
