I'm considering using a smart trainer to do periodic testing for interested riders in the youth program. Ideally something for a short sprint 5-6 sec, a longer sprint (30 s), aerobic power (3-4 min), and threshold power (20 min). Looks like wahoo has a test called the Full Frontal (who dreams up these names anyway?). Anyone tried this? Especially ways to make the test reproducible approx every 4 months, and other factors to make it reasonably accurate for motivating and defining training.
