## Description

Analyze unlimited training videos. Keep 5 complete replays free, or keep every set with Power Pro.

Measure barbell speed, understand every rep and make better loading decisions with Power.

Video velocity tracking
Choose a squat, bench press or deadlift training video. Power analyzes mean concentric velocity, bar path and rep timing directly on your device. Training videos are never uploaded.

Load-velocity profile
Analyze the same lift at 2 to 3 different loads to build your personal load-velocity relationship. When data quality is sufficient, Power provides a velocity-based 1RM estimate.

Fast strength tools
• 1RM from load and repetitions
• Powerlifting scores with DOTS, IPF GL, Wilks and Wilks 2020
• Working weight and plate loading
• Cited adult BMI, FFMI, energy and heart-rate estimates

A generous free plan
Analyze unlimited training videos and keep up to 5 complete source videos with synchronized bar-path replay at once. Numerical results, calculators, load-velocity profiles and training history remain free even after you release an old video. Power Pro adds unlimited local video storage with either an annual subscription or a one-time lifetime purchase.

Your training records stay on your device. Filter video analyses and profile data by lift and source, release videos while keeping their data, or delete records whenever you choose.

All results are for training reference and are not medical advice. Adjust loads for your current readiness and consult a qualified coach or professional when appropriate.
