About Solid Mind Fitness
Solid Mind Fitness is a one-man LLC founded by Jesper Chi, and rooted in one core belief — everything begins with the mind. A solid mind starts with a clear goal — and a clear goal is where real action begins. That’s the heart of our name.
Back in 2015, I was fighting both gout and obesity. At my worst, the pain in my ankles was so severe that I could barely walk. That was when I realized the importance of health and a functional body. Through commitment and consistent effort, I turned my health around completely. Gout became a thing of the past and, in its place, a lifelong habit of regular training was born.
That journey is why I founded Solid Mind Fitness — to help others achieve their goals. If you already know what you’re chasing, we’ll help you get there. And if you’re still searching for that goal, we’re just as happy to help you find it.

專業💪🏾細心👍耐心👏好溝通🤝
每次訓練的前都會很專業的給予最正確的訓練項目,也會有耐心的說明這些項目給予什麼樣的成效。 訓練中或後也會細心的觀察學員的狀態,除了教導學員收操之外,如果如果途中有疲勞累積造成的肌肉過於緊繃,也會施予按摩給予舒緩讓學員能夠有更好的重訓成效。 而且在溝通方面也都能良好的討論,互相求進步。 如果要我介紹專業的教練,我會不考慮的介紹Jasper給我周遭任何的親朋好友。

耐心、專業且值得信任,讓我改善了長期下背痛,也重新找回對訓練和運動的信心。
我一直都有下背痛的問題,所以很怕遇到不知道我身體狀況叫我硬練的教練。但他非常有耐心,每堂課都會確認我的身體感受,並依照當下的狀況調整訓練,不會一味地要求突破極限,但也會在我想退縮的時候給我很有安全感的push,讓我可以很舒服的相信自己其實做得到,不是硬逼自己相信。 我特別喜歡他搭配呼吸的引導,讓我更容易找到正確的發力方式。經過一段時間的訓練,我的下背不適幾乎消失了,也讓我更有信心重新投入重量訓練和自己喜歡的運動。很推薦給想改善身體、安心訓練的人。

Brought Me Back to Me
I have now trained with Jesper for over three years. When I met him, although I worked out regularly and had many different personal trainers, neither I alone nor with trainers had been able to address a longstanding and increasingly complex imbalance issue that had resulted from an old injury. That imbalance, combined with a… Read more “Brought Me Back to Me”

A Game-Changer for My Fitness Journey!
Working with Jesper was one of the best decisions l’ve made for my health. When I started two years ago, I was fairly new to fitness and I didn’t know where to begin. What set Jesper apart was his ability to meet me exactly where I was in my fitness journey. He designed a program… Read more “A Game-Changer for My Fitness Journey!”
我們信任 – Jesper – The trainer we trust
教練非常親切又認真,個性也超級好!疫情期間,還特地替我們規劃在家就能完成的訓練課表(我們太懶惰:),平時也會細心關心我們的飲食,給予適合的建議。 如果想找一位不只是帶你運動,還會從訓練、飲食到生活習慣都一起照顧的全方位個人教練,我們真心推薦 Jesper! Jesper is incredibly friendly, dedicated, and genuinely one of the nicest coaches we’ve ever met! During the pandemic, he even created home workout plans for us (because we were just too lazy 😅). He also pays close attention to our nutrition and always gives thoughtful, practical advice. If you’re looking for a… Read more “我們信任 – Jesper – The trainer we trust”

Wonderful, he knows his stuff!

Knowledgeable, enthusiastic
I worked with Jesper for six weeks, and it was a great experience. He quickly identified the weaknesses that were contributing to my knee pain and IT band issues and built a program specifically to address them. He also introduced fun, effective exercises that kept workouts engaging while targeting exactly what I needed. My knee… Read more “Knowledgeable, enthusiastic”
