Programs that actually work.
Comprehensive, evidence-based training programs and guides for athletes at every level.
AC Joint Separation Return-to-Contact Benchmarks: Shoulder Stability Tests Before Tackling
An AC joint separation that stopped hurting isn't the same as one that can absorb a tackle. See the stability tests that predict contact tolerance.
Adductor Squeeze Return Readiness: Symmetry Criteria After Groin Strain
Adductor squeeze return criteria: use symmetry percent and pain threshold, not a borrowed force number, to time your return after groin strain.
Anaerobic Speed Reserve: How to Calculate and Use It
Calculate anaerobic speed reserve from MAS and max sprint speed, then use the number to profile athletes and pick the right speed or aerobic training bias.
Beach Handball Spin-Shot Power Conditioning: Rotational Power and Landing Control
Beach handball spin shot power leaks through the hips and the landing, not just the arm. Here's a rotational and landing conditioning block that fixes both.
CMJ Depth Inconsistency Is Quietly Wrecking Your Power and RSI Comparisons
A few centimeters of extra dip changes peak power and RSImod more than fitness does. Here's how to standardize CMJ depth and stop chasing noise.
Concussion Graded Exertion Progression: Milestones and Symptom Checkpoints
Objective heart-rate and symptom checkpoints for each concussion return-to-sport stage — treadmill test protocol, 6-stage table, and red-flag criteria.
Flag Football Conditioning: Pull-and-Chase Work-to-Rest Design
Flag football conditioning fails when it's copied from padded football. Build a work-to-rest protocol around chase bursts and flag-pull deceleration.
Futsal Repeated-Sprint Conditioning: Short Court, Hard Stops
Futsal's 40x20m court kills long sprints but multiplies hard stops. Match data, deceleration mechanics, and a repeated-sprint protocol built for cutting.
Futsal Small-Court Intermittent Endurance Profiling: Testing Fitness Around the Turn
A futsal intermittent endurance test built around court width and constant cuts, not straight-line pace. Protocol, norms, and interpretation inside.
High Jump Curved Approach Speed: Finding the Lean-Radius Balance Point
High jump curved approach speed only helps when radius and lean scale with it. The physics, two key studies, and a field test to find your athlete's ceiling.
Impulse-Momentum vs Flight-Time: How Jump Height Is Calculated
The same force-plate trial can show two different jump heights. See why impulse-momentum and flight-time diverge, with a worked example and protocol fix.
Jones Fracture Return to Cutting: Why Straight-Line Running Isn't the Real Test
Jones fracture return to cutting: straight-line running clears too easily. Track lateral load pain during cutting drills to catch refracture risk early.
