I’ve been mulling over how to apply data science principles to my workout routine, and I’m curious what others think. Specifically, if we wanted to compare the effectiveness of a structured leg day versus a more flexible cheat day, could A/B testing give us meaningful insights? I’m wondering how you’d set up variables like recovery time, energy levels, or strength gains to track over a few weeks. Has anyone experimented with this kind of approach, or do you have suggestions for making it practical without overcomplicating things?
