Training Volume
Definition: The total amount of work performed — calculated as sets × reps × weight. Research shows 10-20 hard sets per muscle group per week is optimal for most people.
Why It Matters
Understanding training volume is essential for making real progress in your fitness journey. Without this knowledge, you risk spinning your wheels — training hard but not seeing the results you deserve.
Callio automatically tracks and applies training volume principles to your training program, so you don't need to be an exercise scientist to benefit from evidence-based programming.
