The numbers don't lie.

Across every athlete we have complete before-and-after data for, the average improvement is 0.25 seconds. 19 of 19 athletes who completed both tests got faster, and the fastest mark recorded here is 4.25 seconds. Gains depend on starting point and training age: an athlete starting at 4.85 has more available than one starting at 4.45.

Our Operation 53 block runs 8 weeks, from intake testing to test day. Strength work tapers as speed work ramps so the athlete peaks once, on the day it counts. Most measurable improvement shows up between weeks 4 and 6.

Our athletes average 6.9 inches of vertical gain, and the highest vertical recorded at the facility is 44.5". Broad jump improves an average of 11.0 inches over the same period.

Top speed has a genetic ceiling, but almost nobody tests at their ceiling. Most of the time lost in a 40 comes from start mechanics, acceleration angles, and inefficient movement, all of which are trainable. That is why the 10-yard split moves so reliably: our athletes average 0.19 seconds off it.

Athlete Innovations is a private performance facility in Tampa, FL, led by performance director Cliff Brown. The Operation 53 combine block is capped at 12 prospects per cycle and includes testing, medical and physical therapy, housing, and meals. Athletes who trained here have signed with NFL clubs and been drafted.

Sprints are captured with electronic timing gates rather than a handheld stopwatch, jumps on force plates, and top speed with GPS. Every published number is a measured result for a named athlete, with the before and after both shown. Nothing is projected or estimated.
