Medical × Training Science × Field Implementation
LOOPZ Inc. is a human performance company that supports individual decision-making about their bodies through measuring, understanding, and systematic intervention.
Human physical potential is still not properly understood.
"Because of age" "Because of lack of talent" "Because of injury" We have witnessed countless situations where physical potential is closed off for these reasons.
However, in reality, most cases are simply due to improper measurement and wrong sequencing.
LOOPZ exists to unlock "true potential" through data and expertise, not through intuition or willpower.
Measure, Train, Condition Everything in the right sequence.

Physical assessment and evaluation (Sprint / Jump / Strength / Range of motion, etc.)

Training design based on purpose and stage (Individual / Team / Sport / General)
