Can ArmCare testing predict potential velocity gains?Updated 2 months ago

Yes. Studies show that pitchers with higher internal rotation strength, grip strength, and an optimal ER/IR ratio tend to throw harder. 

ArmCare’s data-driven approach tracks:

  • Strength-to-velocity ratios – Ensuring strength development keeps pace with velocity increases.

  • Fatigue resistance trends – Preventing performance drop-offs due to overuse.

  • Muscle balance and stability metrics – Identifying pitchers who are primed for velocity gains and those who need additional strength development before pushing intensity.

We guarantee at least a 4 mph improvement in 10 weeks for athletes throwing under 90 who test weekly and complete 5+ strength sessions prescribed by the app.
