This is a video tutorial for my therapeutic exercise profile on ChiroUp that I use to create a CUSTOM exercise program for every single patient and online consult client.

If you would like to receive your own list, you can do so through my office - Coastal Performance Chiropractic (TX residents only) - or an online consult through The Educated Meathead.

This is for entertainment and education only, this is NOT direct medical advice.
 
Dr. Christopher (MARV) Marvin DC has been involved in health, wellness and fitness for over 18  years. He earned his Bachelor of Science in Exercise Science from Sonoma State University and his Doctor of Chiropractic from Palmer College West in San Jose, California as class valedictorian. Dr. Marv is the owner of Coastal Performance Chiropractic in Houston Bay Area. He also currently offers telemedicine video calls and nutrition coaching through the office for all TX residents. Dr. Marv recently launched The Educated Meathead that will be developed over the course of this year. Currently the website has his first online course, seminar recordings, CUSTOM workout programs, workout programs via subscription, and consults (he cannot legally diagnose non-TX residents with that option but still provide therapeutic exercise and nutrition/lifestyle recommendation).
