Playing around with logos

Hey readers! So I am looking to brand myself. I want to eventually create an online following like other fitness gurus (IE, BodyRock.TV, Hodge Twins, Furious Pete, Wolfe, etc) But I don't think I can do it just being Heidi. So I am looking into branding myself as a trainer and possibly a company. Let me know what you think of this so far.

I made the OM sign look like a three because I am playing around with the phrase "Healthy, Hot and Happy" Or "Healthy and Happy with Heidi"

I was originally going to go with 4H Fitness and Yoga because I wanted to do "Healthy, Hot, and Happy with Heidi" but I am going to take out an H because

1. It sounds like a horse riders club

2. I like 3 better because its cleaner and I can use the OM sign in a fun way

Any feedback would be very appreciated! If I implement any of your ideas I will give you a shout out or referral on my page!
