Programs that actually work.
Comprehensive, evidence-based training programs and guides for athletes at every level.
IMU Validation for Coaching: Reliability, Validity, and Practical Use
Before trusting a jump number, check the sensor behind it. This guide covers reliability, validity, and sensitivity tests with 800Hz field protocols.
IMU vs Linear Position Transducer (LPT): The Complete Guide to Velocity-Based Training Equipment
IMU or LPT — the wrong pick wastes budget on unusable data. Compare accuracy, cost per athlete, and setup time before choosing your VBT sensor.
Deadlift Load-Velocity Profile Guide: 1RM Estimation and Velocity Zones with 800Hz IMU
One lifter used an 800 Hz IMU to build a deadlift load-velocity profile and added 10.7% to their 1RM in 12 weeks. See the protocol and data.
Hex Bar Deadlift Load-Velocity Profiling: A Complete VBT Guide for Maximal Power Output
Hex bar deadlifts move 21% faster than straight bar deadlifts at the same load, which changes your velocity zones. See the testing protocol and V-L curve.
VBT for Masters Athletes: Complete Velocity-Based Training Guide for Lifters Over 40
Training past 40? Use 800Hz IMU autoregulation to cut injury risk, protect power output, and adjust load to your daily readiness, not a fixed percentage.
VBT Velocity Thresholds by Lifter Experience: Novice vs Advanced Profiles Compared
Same velocity threshold for every lifter? Thats a mistake. See how novice and advanced cutoffs differ, using 800Hz IMU data and individualized profiles.
Velocity Deficit Explained: How to Measure and Interpret the Gap Between Strength and Speed
A high 1RM does not guarantee explosive movement. Velocity deficit measures the real gap between strength and speed, with steps and ranges by sport.
Velocity Profiling for Throwers: Data-Driven Training for Shot Put and Rotational Events
Shot put and discus throwers plateau when force and velocity fall out of balance. Profile the load-velocity curve, flag a 30% F-V gap, and fix it directly.
Velocity Threshold Cycling Explained: How to Rotate Velocity Zones Across a 12-Week Block
Training the same velocity zone for months stalls progress. Rotate strength, power, and speed thresholds on a 4-week cycle validated with 800Hz IMU data.
Box Jump vs Broad Jump: Which One Fits Your Goal Better
Box jumps and broad jumps train different power vectors. Compare kinematics, muscle activation, and metrics from 800Hz IMU data to pick the right one.
Contrast Training Explained: Combining Heavy Loads and Explosive Work to Maximize PAP
Heavy squat to jump squat, bench press to medicine ball slam. The PAP mechanism behind contrast training and how 800Hz IMU validates the optimal protocol.
Force-Velocity Imbalance Explained: Diagnose Weakness with an 800Hz IMU
Jump numbers stall even though you train hard? An FVi score from an 800Hz IMU separates a force deficit from a velocity deficit in minutes, not guesswork.
