Mark Crabtree is a trainer and founder of Ignite Fitness Inc. Mark has plenty of certifications under his belt including being a certified athletic trainer for professional athletes. He drew his fitness inspiration from Arnold Schwarzenegger, which made him want to get stronger and get bigger muscles. He decided to learn more about training and rehab when his doctor said a previous shoulder injury, which he got from training, was fine yet he still felt pain. He has since become the kind of trainer athletes don’t want to see, as frequent visits meant something’s wrong with their body.
