I have been learning so much and picking up more clients, so yes, it's getting that much more exciting and busier (a good thing when you do what you love). As a personal trainer, we pave our way through this world of muscles, breathing, stretching and more importantly, teaching this information to our clients. The most vital and important part of a workout program to me is FORM. There is no point in doing and exercise when you are the slightest bit unsure of your form. Check yourself in the mirror!

Remember, you are trying to improve your well-being when you workout, not injure yourself.
