The athlete behind SplitLab.
I’m Alex Liu, a student-athlete who is passionate about lifting, sports, and helping others become better athletes.
It started with trying to dunk.
I began training seriously after watching the first game of our boys’ varsity basketball team, with one concrete goal: to dunk. This goal introduced me to the weight room, grew into my interest in studying athletic training, and eventually led me to track.
Recording my training showed me something I hadn’t expected: my squat and approach jump did not improve at the same pace. Getting stronger did not mean jumping higher every week. Sometimes I hit a plateau for days or even weeks. Those ups and downs honestly made me question whether my program was working. As I gained more training experience, I began to understand that progress could be uneven. I learned to focus on long-term progress.
I often record videos of myself sprinting and lifting to help me work on my technique. I think this is a great habit. These are pictures of me working on my acceleration and 30m fly when I first started training for speed.
A place to keep the whole story.
I made SplitLab to share the training ideas I have tested, the mistakes that changed my approach, and the results I am still trying to understand. Statistics helps me sort through the evidence. The website is still mainly about being an athlete and learning from the work.

I built SplitLab with coding assistance from Codex. I choose the topics, share my own training experiences and records, and continue to revise the content.
