Understanding Your Training Load
Last updated: October 29, 2025
What is Training Load?
Training load is like having a personal fitness coach that tells you when to push harder and when to rest. It measures how much stress your workouts put on your body, helping you get fitter without burning out. Think of it as understanding the "dose" of exercise your body receives - ensuring you're doing enough to improve but not so much that you risk injury or exhaustion.
Training load helps answer three critical questions:
- Am I training hard enough to improve?
- Am I recovering properly between workouts?
- When am I ready for peak performance?
The Science Behind Training Load
Our training load calculation is based on the internationally recognized TRIMP (Training Impulse) methodology. This approach has been validated in numerous peer-reviewed studies and is used by professional athletes, sports scientists, and leading fitness platforms worldwide.

Important Note
While our training load calculations are based on validated scientific research, they should be used as a guide alongside your own body awareness and, when appropriate, guidance from qualified fitness professionals. Individual responses to training can vary.
