With recent advances in phone technology, camera quality, and phone computational power, the ability to track movements via computer vision without the need for additional hardware has become more widespread. A number of applications are commercially available at affordable prices and even completely free increasing the accessibility of velocity based training beyond elite and professional sporting contexts. These applications already offer high levels of validity and reliability for bar path, velocity, range of motion, and power metrics. The affordability, easy of use and reliability of the data makes smartphone applications an appealing option for coaches and athletes at every level.
