Client Testimonial
"What I enjoyed most about working with Aishea & Phase IV is the wonderful attention I received. It was very personal and I felt they really cared about me and my health. Aishea was extremely helpful teaching me hydration and nutrition for my training and the marathon. She gave me all the tips so I can do great and stay healthy. Aishea followed up with me showing concern and also encouraging me to do the right thing for my body. I have had a lot of stomach issues in past marathons so this year I followed Aishea's guidance and I focused on taking only 20% of the calories I burned so it was great. No issues with my stomach, I used the products Aishea suggested and had a very successful marathon." - Maru Trimmer, Phase IV Client & Marathoner
