How to Accurately Measure RSI with Drop Jumps
The wrong drop height skews your RSI numbers before the test starts. This guide covers optimal box heights, flight-time calculation, and norms by sport.
Stretch-Shortening Cycle: The Plyometric Foundation
A countermovement jump beats a static jump due to the SSC, but fast and slow SSC need different training. Here's the mechanism and RSI benchmarks.
How to Design a Plyometric Program: Science-Based Blueprint
Too many foot contacts too soon causes tendon pain, not power. Get the volume tables, exercise order by phase, and the RSI tracking that keeps it safe.
How to Train for Vertical Jump Improvement
Vertical jump stalls when strength, plyometrics, and tracking aren't sequenced. An 18-week guide layers strength work, contrast loading, and IMU jump data.
Calf Raise Variations: Science-Based Guide to Ankle Power and Hypertrophy
Master standing, seated, single-leg and eccentric calf raise variations. Research-backed loading schemes, EMG data, and protocols for strength, power.
Cheerleading Tumbling Power: A Science-Based Training Framework
Build explosive cheerleading tumbling power with this science-backed guide: ground force mechanics, plyometric progressions, velocity norms.
How to Periodize Plyometric Training
Too much plyo volume stalls power gains; too little wastes the year. Weekly ground-contact caps, phase structure, and RSI targets that keep progress safe.
How to Train Reactive Strength for Athletes
Reactive strength runs on drop jumps and ankle stiffness drills, not box jumps alone. Get RSI targets, an 8-week plan, and how to measure each session.
Plyometric Training Dose-Response: Research Analysis
More plyometric volume isn't always better. A meta-analytic review breaks down the optimal volume, intensity, and rest for jump height gains.
Plyometric Training Principles for Athletes
Jump volume climbing but reactive strength flat? SSC mechanics, load progression, and periodization principles coaches use to break the plateau.
Box Jump Progression Guide: From Beginner to Advanced Plyometrics
Exact box heights by week (30-75cm), the RSI formula with 2.0/2.5 benchmarks, contact-time targets under 200ms, and a 4-test readiness check.
