Mahdi is a fantastic trainer! After only 9 one hour sessions, I am stronger, more flexible, and have lost 6 pounds with no new aches or pains. This is even more of an achievement because I am an opinionated octogenarian with an artificial hip, two prosthetic knees, a recently strained right bicep, and a pair of hearing aids. Hypesthesia of both lower legs still diminishes my sense of balance despite lumbar spine fusion and decompression surgery six months ago. For 88 years, I have consumed fluids only to quench my thirst. To help me stay more hydrated, Mahdi bought me a water bottle and has patiently convinced me to try drinking 40 oz of water daily instead of my usual 8 oz. Because I am sufficiently optimistic about the progress thus far, I have paid for sixteen more trainer sessions.
