Health Coach and Personal Training Certificates

It's a great profession if you're able to follow through. Just understand that the passion you have for it WON'T be shared by the majority of people you workout with. That's usually going to be the reason why you end up working out with them in the first place because if they had passion for it, they probably wouldn't need your help.
Most clients will hire you for weight loss to get ready for an event, or just so that they can be taught to workout. You will get clients that stick with you for a long time (I have a couple of them now that won't likely step foot in the gym UNLESS they are coming to see me for a session), but the majority of your clients will be short term (1-3 months or less). So that means you WILL have to learn how to be good at sales. Especially if the sessions you sell are $60 an hour more. For many that's 10 sessions, training 2 times a week at the cost of $600 for 5 weeks. This is where I see people with certs fail. They may know how to train, but CAN'T get anybody to train with them. Consequently, they only do it part time and may end up with just 1-3 clients a week while trying to hold down another full time job, since 1-3 clients a week MAY (may be less) only net you $120 in income for that week. And then of course you want to get in your gym time and if you're in a committed relationship, you've got to balance that out too.
So just be sure that it's something that you're committed to. I'll be the first to tell you that you will get A LOT more rejections from people on training and that it takes a minimum of about 3 months for a beginning PT to build a decent clientele if the facility they work at has a good system to build off of. If not (and many require you to self generate), it may take even longer.

Just want you to understand that just because you've been successful at doing it, and may have good knowledge, actually doing it for a living and creating income from it isn't as easy as it seems.

I'm doing the same thing. I've begun my certification thru NASM. I still have a ways to go; however, I feel like I can use my own experience to change mindsets of others and help them realize they too can do it.

Good for you @griersonwedding2015!
