Foster load is a method for calculating training load based on perceived exertion: how hard the workout felt, from very easy to maximal effort.
📌 Good to know
Foster requires no sensor. That is what makes it usable everywhere, including where power and heart rate are not available: swimming, strength and conditioning, team sports.
Where the data comes from
Foster load is calculated from the RPE entered on the workout. There are two ways to provide it:
your athlete enters their perceived exertion after the workout;
you estimate the effort yourself when planning.
👉 Perceived exertion and estimated load
👉 To make RPE mandatory: Strict mode
👉 The three load tracking methods
👉 Using training load to train better (Nolio blog)
