Episode notes
Use Stricter Criteria When Possible
- Consider stricter entry criteria (AspiTar): aim for ≥80% limb symmetry for quad strength and eccentric CMJ impulse before running.
- Use dynamometer targets (~2 N·m/kg as minimum; 3 N·m/kg ideal) to guide progression if available.
Progress Pogos From Double To Single
- Start plyometrics with low-load hopping/pogo drills (double-leg then progress to single-leg) to build ankle stiffness and tolerance.
- Scale intensity via height, tempo, stance (double → staggered → single) and monitor knee response during transitions.
Scale Horizontal Jumps By Intent
- Use sub-maximal to maximal broad jumps to progress horizontal power; vary from two-leg sub-max to single-leg maximal hops as tolerated.
- Include bounding and hop series to bridge between bilateral and single-leg tasks while observing landing strategy.
