@Microsoft your customer service is the worst. No help to resolve an issue and no one answers the stupid support chat. Seems like trying to build a rocket that flies and then land it. I guess that's why only @elonmusk can?! Do you need a bad review to in order to help a client?

Off-season isn’t just prep—it’s a chance to shape the ASR.
In my latest article, I cover how to develop ASR without max sprinting:
✅ Uphill sprints
✅ Tempo runs
✅ 10x10 repeat sprints
✅ Myotype-based HIIT

Can periodization shape your ASR without directly training top speed?
In this new post, I break down how multi-targeted blocks can influence the anaerobic speed reserve (ASR)—even when max sprinting isn't the focus.

✅ What to prioritize during the accumulation phase ✅ Why uphill sprints are a smart MSS alternative ✅ How fatigue affects sprint mechanics + injury risk
📉 Less noise. More clarity. Better training decisions.

🏃‍♂️⚡ Same workout ≠ same stimulus
Absolute pace.
3 different responses.
An ASR perspective: 🔴 Sprint-type → higher neuromuscular strain

Concentric impulse is the key determinant of jump height (via take off velocity).

So why does eccentric rate of force development or eccentric impulse matter?

Happy to announce the {perchr} package in R. This provides a simple R interface to the Perch API, enabling authentication, retrieval, and organizing Perch data into R for analysis.
