This is Charles. I am a personal trainer yet I still really find this one useful! I have been learning a lot of additional things. I am so thankful we have this kind of site. I hope I will be able to share my knowledge here too.
By the way, If you want to check the kind of job I have, you can check it here - How I Became A Personal Trainer
. It's a tough yet fulfilling job for me.
Hope to get along with all of you.
