Can you give more detail on how to calculate training load?

A popular method is a 1-10 scale which coincidentally corresponds to general lactate levels. Another very simplistic method, which is what we are using in CXC Academy, is an intensity scale 1-5 that corresponds with the training levels 1-5.

In short, a consistent unit of measure for time and intensity is necessary to measure load. We use hours to measure duration and a 1-5 training intensity scale to measure intensity for purposes of CXC Academy. Measuring load and not just duration alone is an excellent method to measure training and how much one can handle week to week, month to month and year to year.

For example, one workout might have 15 minutes of warm-up, 20 minutes of Level 4 intervals (5X4minutes) with 4 minutes recovery in between and then a 15 minute cool down. The total training load of that workout would have a load of:

Level 4 – 0.33 hrs X 4 = 1.33 TL.
Level 1 – 15min warm-up+4min*5 recovery time between intervals+15min cool down = 50min or 0.83hrs
0.83hrs X 1 = 0.83 TL

Total effort is 1.33TL + 0.83TL = 2.17TL

We often analyze total training load per training level per week. For example, 10TL for the week in Level 1 is 10hrs of Level 1 training for that week.

I hope all the math makes sense,
