Anthony Mendes

Personal Trainer
Location: Petaluma
Email: Anthony.Mendes@activewellnesscenter.com
Philosophy: The NAVY seals have a 40% rule: When you feel mentally finished, you feel exhausted and ready to quit, you’re only 40% done. I enjoy training because it teaches many life skills, including self-discipline. I also believe in safe progression. Every phase of your fitness journey has a prerequisite, and proper progression begins with optimal posture and proper form.
