Think of yourself as a massage athlete. Manual therapy demands skill, strength, and endurance, just like a track and field runner or baseball player. The symptoms of overtraining are just like an athlete and include fatigue, lack of energy, pain, insomnia, and depression. Rest is essential for the treatment of overtraining. You can take your resting heart rate in the morning and if it is higher than the previous day, you may not have recovered from the previous day.
Insightful strategies for self-care and injury prevention are included in the inspiring book, Creating Peace with Your Hands, written by Karina Braun.
