I like a lot of things about yoga - its an intro to good music; with each good teacher you study with, you learn a lot about them personally; it's not just about specific technique or poses. I also like Shavasana - not too many exercise routines let you nap at the end of them. You don't see nap pods in CrossFit gyms.

One of the pillar ideas of how CrossFit thinks of physical fitness is how competent an individual is at cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, coordination, accuracy, agility, and balance.

As the issue of youth fitness - from obesity to proper exercise regimens - takes on more resonance in schools and communities across the country, CrossFit Kids and other preschool fitness programs are raising questions about when and how children should start playing organized sports or hitting the gym.

When I was first introduced to CrossFit, I found it to be the hardest workout that I'd ever done. It wiped the floor with me, and I fell in love with it immediately. The results that I have seen in my strength and physicality have been unparalleled to any other things I have ever done in my more than 20 years in the fitness business.

My husband and I own a CrossFit Gym. Crossfit is perfect for me because it's always competitive, all the workouts are in a class environment, and it's different every day. It's a constantly varied functional fitness workout done with intensity.
